    At present, the desktop sockets manufactured by Anssin mainly include the new national standard, American standard, European standard, British standard, South African standard, Brazilian standard and Argentine standard.
    As follows:

New national standard

New national standard

    In addition to China, the new national standard is also used in Australia, featuring three flat heads;
    The plug and socket pattern for use in China is specified in publications GB 2099-1 and GB 1002-1. The Chinese plug is a 3-wire, grounded plug rated at 10A/250VAC used in Class I applications in China. The plug is nearly identical to the Australian plug pattern except that the contact pins of the Chinese plug are slightly longer (1mm) and the plug body dimensions vary slightly. The cord sets can be terminated with a variety of IEC 60320 connectors and have a maximum output rating of 10A. China requires that plugs, connector couplers, and cable used in the construction of the Chinese cord sets be tested and approved by the China Commission for Conformity Certification of Electrical Equipment (CCEE) and must bear the CCC mark.

   Australia’s plug and socket is manufactured in SAA document AS/NZS 3112. It is used in Australia, New Zealand, Fiji, and Papua New Guinea. The standard rating of plug and socket is 10A, but 15 and 20A models are also available. The cord sets can be terminated with a variety of IEC 60320 connectors and have a maximum output rating of 10A/250VAC.
    Australia has several state electrical testing agencies; the others usually accept a component approved at one of the agencies. The Australian agencies also accept component approvals from SNZ, the New Zealand electrical testing agency, and vice versa.

American Standard

    The American standard conversion socket can be used in the United States, Canada, Mexico, Venezuela, Laos, Peru, Nigeria, the Cayman Islands, etc. It is characterized by one round and two flats.
American cords utilize the NEMA 1-15, 5-15, 5-20, 6-15, and 6-20P plug standards. In the U.S., these straight-blade plugs are detailed in NEMA (National Electrical Manufacturers Association) publication WD6 and are incorporated into UL 498 by Underwriters Laboratory. Canadian plug and socket standards are outlined by CSA in publication C22.2, No. 42.
    The NEMA 5-15P style plug is also used in Mexico, Japan, parts of Korea, Taiwan, Central America, Colombia, Venezuela, Ecuador and on the west coast of South America. The electrical systems in developing countries are usually ungrounded. Interpower Corporation does not recommend cutting off the ground pin so that the plug can be mated with a two-pole, ungrounded socket. This eliminates the safety ground connection. We offer ungrounded cords, rated at 2.5A–15A/125VAC.
    All include UL listing and CSA certification. we also offer other cable sizes and types. Applications include data networking equipment such as power servers, computer data storage systems, and industrial equipment requiring more than the standard 15A/125VAC, but less than 20A/250VAC.
The North American molded hospital-grade power cords and cord sets are designed for use in hospital and medical settings. They carry the characteristic “green dot” on the plug indicating hospital-grade on the plug. The cord sets can be terminated with a variety of IEC 60320 connectors and have a maximum output rating of 15A/125VAC.
    Equipment manufacturer’s specifying power cords for their equipment should be aware of changes made in 2000 by UL and CSA to two major equipment standards. In an effort to harmonize with equivalent IEC standards, U and CSA made changes to information technology equipment standards. (UL 60950 and CAN/CSA C22.2 No. 60950) and medical equipment standards (UL 60601 and CAN/CSA C22.2 No. 60601).
    UL 60950 and CAN/CSA C22.2 number 60950 state that for all new submittals, the ground conductor of power cords must be green/yellow in color.
UL 60601 and CAN/CSA C22.2 number 60601 require the ground conductor to be green/yellow and the neutral conductor to be light blue, for power cords on all new submittals. Indications are that UL and CSA may not be rigidly enforcing these requirements and may be making allowances for the use of the traditional North American (BWG) colors. Check with agency officials if you have any questions regarding an application.
    In both cases, Interpower Corporation recommends the use of BBG/Y (Brown, Blue, Green/Yellow) color coded cable, which is accepted by UL and CSA. Previously, it was necessary for equipment manufacturers to distinguish between North American power cord conductor color coding, i.e., black, white, and green, and the international conductor color coding, i.e., brown, blue, green/yellow. Now equipment manufacturers have a standard color-coding scheme. However, both color coding options are available from stock.

European standard

European standard

    The standard, Class I grounded mains, plugs used in Germany, Austria, the Netherlands, Sweden, Norway, Finland, and Russia are the CEE 7/4 and CEE 7/7 plugs (also known as “Schuko”). Because this standard is used so commonly throughout Europe, we refer to it as the “Continental European” standard. Both styles have two 4.8mm round contacts on 19mm centers. Grounding is achieved through the grounding clips on the sides of the plug body. The CEE 7/7 plug also has a female receptacle, which permits it to be plugged into the French/Belgian sockets that have a male grounding pin. (For more information, see France/Belgium) All stocked Interpower Continental European cords utilize the CEE 7/7 plug.

  The standard wall outlet in Europe provides consumers with 230V single-phase power. The standard practice for delivering this voltage differs from the North American method for providing 250V to the outlet. In North America, a 250V outlet would be connected to two live legs, each having 125V potential with reference to ground. The European system has one live leg carrying 230V with reference to ground, a neutral (the system ground), and a safety ground. Consequently, the European 230V system is wired similar to North American 125V house wiring.
    Practices differ mainly in the area of polarization. Typically, Europeans do not maintain consistent identification of line and neutral throughout their power system as is the practice in North America. Consistent with this practice, the Schuko plug can be rotated to either of two positions and plugged into the socket. Thus, the common electrical system in Europe is unpolarized (i.e., line and neutral are connected at random). In fact, most plug types used in Europe are not polarized.
    Schuko cord sets are available in three stocked cable sizes. Depending on cable used the cords and cord sets are rated for service between 2.5–16 amps at 250 VAC. Interpower™ Schuko power cords and cord sets carry all the major European approvals.
    Countries that occasionally use the CEE 7/7 (“Schuko”) plugs: Portugal and Spain.
    Note: The Continental European plug will fit 10A sockets in Italy and Denmark. However, the Continental European plug will not be grounded. Therefore, we recommend specific plugs for Denmark and Italy.
    Note: Sweden does not allow the use of rewireable plugs for medical use.
    Note: Russian approval agency GOST requires the CEE 7/7 plug be used for 16A applications.
   

French socket form size chart

    France and Belgium have a standard socket which is not compatible with the CEE 7 socket that is standard in Germany and other continental European countries. The reason for incompatibility it’s that grounding in the French/Belgian socket is accomplished with a round male pin permanently mounted in the socket. The CEE 7/7 plug bridges the differences between the two types of sockets. It has grounding clips on both sides to mate with the CEE 7 socket and a female contact to accept the grounding pin of the French/Belgian socket. See the illustration below.
     Note: The CEE 7/7 plug is polarized when used in the French and Belgian electrical system.
There are two types of polarization: physical and electrical. The illustration above demonstrates physical polarization, i.e., the ability to allow or stop a connection being made with the plug in one or more positions. Electrical polarization occurs when each line or connection of the supply is connected to a specific contact on the plug or socket, which is dictated by either a specific standard, or common practice. France and Belgium have no standard for wiring connectors; therefore, electrical polarization is non-existent.

    There are several types of plugs used in Italy (including the Continental European CEE 7/16 plug).
However, the official standard is the CEI 23-16/VII. The Italian system is relatively standardized in Libya, Ethiopia, and Chile and is also used in parts of Northern Africa.
    The Italian grounded plug/socket standard, CEI 23-16/VII, includes two styles rated at 10A/250VAC and 16A/250VAC and differ in terms of contact diameter and spacing. Because they can be inserted in either direction at random, they are unpolarized. Both carry the Italian safety agency, IMQ.

British Standard

British Standard

    The official plug standard in the United Kingdom since 1962 is the BS 1363 plug. (The previous plug standard was BS 546, still found in older buildings.) The BS 1363 plug is also used in Ireland, Hong Kong, Malaysia, and Singapore.
    British standard BS 1363 requires use of a 3-wire grounded and fused plug for all connections to the power mains (including Class II, 2-wire appliances). The BS 1363 plug contains a BS 1362 fuse, which is designed to protect the cord and branch wiring back to the branch circuit protector installed in the building.
British power outlets incorporate shutters on line and neutral contacts to prevent someone from pushing a foreign object into the socket.
    Appliances tested and approved by British agencies can only use approved plugs, and these are tested by ASTA-BEAB to BS 1363. ASTA requires that their mark be molded into the plug.
The plug is rated from 3–13A/250VAC, depending on the fuse. Standard Interpower™ British cords and cord sets are approved by ASTA and carry the ASTA-BEAB.

India, South Africa standard

India, South Africa standard

    India and South Africa have standardized on a plug which was originally defined in British Standard 546 (the standard in the United Kingdom before 1962, when the United Kingdom replaced it with BS 1363). The BS 546 standard is also used in parts of Southern Africa (i.e., Ghana, Kenya, Nigeria), the Middle East (i.e., Kuwait, Qatar), Nepal and parts of Asia and the Far East that were electrified by the British.
    Our cords are manufactured to our specifications in the U.K. It meets British standards, but carries no approvals. The plug is rated at 15A/250VAC. No approvals are required in the countries where it is used.
    Note: India now requires BSI approvals. Currently not all Indian plugs carry this approval.

Brazilian Standard

    The Brazil plug and socket is specified in Brazilian standard NBR 14136:2002. There are two plugs per the new standard, one rated at 10A and the second at 20A. The Brazilian NBR 14136 standard also includes receptacles. The standard is based on the international IEC 60906-1 standard, developed to encourage countries to adopt one plug and receptacle for global use.
    Prior to the release of NBR14136:2002 there were three different types of plugs used in Brazil. First is the NEMA 1-15 which is a two-blade ungrounded plug used in North America and Japan. Second is the NEMA 5-15 a plug with two flat line and neutral blades and a round ground pin also used in North America and Japan. Lastly, the Euro plug which is also used throughout continental Europe.

Argentine Standard

Argentine Standard

      The standard plug for Argentina is defined by IRAM 2073. IRAM is the standards agency for Argentina. The Argentine plug, which is used in Class I applications in Argentina, is similar in appearance to the Australian plug. However, this plug differs greatly from the Australian plug—the pins are one millimeter longer, the body dimensions change slightly and most importantly, the wiring differs. The positions of the line and neutral contact pins are reversed. For this reason, great care must be taken when manufacturing equipment for export to both Australia and Argentina, as well as specifying the correct cord or cord set for use with equipment. The Argentine plug is a 3-wire, grounded plug, rated at 10A/250VAC. The cord set is terminated with an IEC 60320 connector rated at 10A. All cord sets carry the appropriate approvals.

Small knowledge of voltage and electrical appliances around the world

  1. There are basically two voltage systems in the world, one is about 110 volts, such as the voltage on a ship, so its equipment is designed according to this low voltage. The other is around 220 volts, including 220 volts in China and 230 volts in the UK. Chinese electrical appliances that belong to the same voltage system are brought to the UK for use. Voltage shouldn’t be a problem at all, because most electrical appliances have a voltage fluctuation range of 20%. For example, Haier’s color TV’s floating range is marked with: AC90-260V50Hz, as a precision electrical product, color TVs can be used at voltages of 90 to 260 volts, not to mention other equipment such as electric stoves and rice cookers. The 230 volts voltage just allows them to heat up faster without any problems.
  2. Many electrical appliances have adaptable voltages, which can be suitable for 110V-240V voltages, such as chargers, laptops, computers (need to adjust), shavers, etc. You can look at your electrical signs.
  3. Countries where the voltage is 230-240 volts can also use all electrical appliances in China, because the domestic voltage can reach up to 250 volts.
