The power plug(ac plug) should be a very common product in our daily life, but the production of the plug is not a very simple thing. Because different countries have different performance requirements for plugs, the official requirements for plugs in some regions of the world are also very different. Let us briefly introduce the product standards of power plug insert.

North American standard plugs are manufactured according to the National Electrical Manufacturers Association 1-15, 5-15, 5-20, 6-15, 6-20P, TT-30P plug standards. The plugs they make are fully certified by the National Electrical Manufacturers Association and Underwriters Laboratories. The plug standard in Canada is the Canadian Standards Association (hereinafter referred to as “CSA”) No. C22.2-42, an Underwriters Laboratory approved and CSA approved plug that can be matched with various sizes and types of cables, such as power servers, Computer data storage systems, network equipment and industrial equipment, where the standard 15A/125VAC plug is the most popular. North American standard injection molded power cords and plugs are commonly used by medical institutions and are easy to install, and we have a dedicated medical-grade plug system in our products. One side of the wire is an IEC-60320 connector with a rated current of 10A.

The pin of the Japanese plug is equivalent to the American standard plug of the North American NEMA standard. But in other respects, JIS 8303, the standard for Japanese plug manufacturing, adopts relatively stricter dimensional requirements, different marking requirements, and mandatory testing and approval by Japanese testing agencies. They require that the cable must comply with JIS C3306. Plugs and connectors require DENAN approval. PSE (Electrical and Material Product Safety), it should be mentioned that Japan has two power frequencies, 50Hz and 60Hz. When purchasing, you need to distinguish the power frequency you need to buy.

In Germany, Austria, the Netherlands, Sweden, Norway, Finland and Russia, the Class I grounding power plugs used uniformly are the CEE 7/4 and CEE 7/7 plugs, which are also called “Schuko”. This standard is very common throughout Europe, so we also call it the “Continental European” standard in our industry. There are two popular styles produced according to this standard, they both have two 4.8mm circular contacts with 19mm center to center and grounding is achieved by grounding clips on the side of the plug body. The CEE 7/7 plug also has a female socket that can be inserted into a French or Belgian socket with a male ground pin.

In addition, the plugs and pins produced by Green Electric are made of nickel-plated copper, and the plastic component is PBT 30% halogen-free flame retardant. There are two forms of hollow and solid. They are suitable for all standard AC plugs, covering Europe. VDE, American UL, South Korea KS, Japan T-MARK, Argenyan IRAM, Brazil BSA, British BSI, China CCC, etc., and also meet the PATH certification standards of ROHS and GSG. As a foreign trade supplier of electrical accessories from China, Green Electric has a very complete range of international products. There is a special point that they can rely on their own independent production department to produce customized products, and are also willing to accept ODM and OEM business cooperation , The price of goods is also very reasonable, and the service attitude is also first-class.

ac plugs

In the daily life and work of modern people, the use of plugs is very frequent, but the understanding of the correct use of power ac plugs has not aroused enough awareness. Let’s talk about the importance of correct use of ac plugs.

  1. The choice of power plug

First of all, should choose the plugs produced by regular manufacturers with safety certification marks. Now each country and region in the world has its own safety certification system. The choice of plug first selects products that meet the safety standards of the place of use, such as: Australia And New Zealand’s SAA (Standards Association of Australia) certificates, China’s CCC certificates (China Compulsory Certification), Japan’s PSE certificates, Germany’s VDE certificates (Verband Deutscher Elektrotechniker), the United Kingdom’s BSI certification, the United States’ UL (Underwriter Laboratories Inc. ) certification, CSA, cUL in Canada, BSMI in Taiwan, IRAM in Argentina, NOM in Mexico, Brazil Inmetro TUV Approval, VDE in Germany, SII in Israel, IMQ in Italy, KC in Korea, South Africa’s SABS certification, Switzerland’s SEV certification, and more. In addition, when choosing the ac plug, you should also choose a suitable plug according to the rated current, rated voltage, and power properties of the electrical appliances you use. Do not overload the rates of plug, otherwise, it will easily cause the plug to heat up and cause a fire. Finally, choose a suitable plug according to the situation of the socket, and do not use violence to change the original shape of the plug pins, otherwise, it is easy to cause poor contact between the plug and the socket and cause the socket and the plug to heat up, which is also a fire hazard.

  1. Use of the ac plug

First of all, make sure that the power plugs and the hands holding the plug are dry. Do not use the plug and hand with water to plug in or unplug the plug, so as to avoid electric shock accidents.

When getting the plug, first check whether the plug pin is loose or deformed. Because the plug may be damaged during transportation, it must be checked before use to avoid using abnormal plug products.

Do not use violence when plugging and unplugging, and pay attention to whether the contact between the plug and the socket is good and whether there is any looseness. During use, pay attention to the use of the plug. If you find that the plug is hot or deformed, you should turn off the electrical appliance at the first time, and then check and deal with it in time. When the electrical appliance is not used for a long time, it is necessary to unplug the plug in time to prevent the plug from heating up in the power-on state for a long time and causing a fire. In addition, unplugging the plug in time and turning off the electrical appliances that have not been used for a long time can also save electricity and do environmental protection. contribute.

The above safety issues related to the use of power plugs, I hope this knowledge can improve everyone’s awareness of the safety of electricity consumption, recognize the hidden dangers of electricity consumption hidden in the use of plugs, and help everyone to buy safe and satisfactory products. If you have questions about ac plugs, power cords, extension cords, etc., please feel free to contact Green Electric  and you will get a satisfactory answer in time.

What Is A Power Cord ?

Brief Summary

The power cord is an electrical component that we often use it in our modern daily life. The power cord is also called the power supply cord. It is a necessary path to provide energy sources for electrical components or equipment. It is one of the basic elements of electrical products or components, such as computers, televisions, printers, rice cookers, hair dryers, ect. that we often use in work and life.

The power cord generally consists of 3 parts: plug, wire / cable and terminal connector.

power cord

Below we will learn more about the power cord from many aspects.

The history of power cords

As early as BC, the Greek scholar Milly discovered the existence of “electricity”. In early 1600, the British doctor Gilbert formally wrote an article about the phenomenon of “electricity”. Later, the British Gray and French Dufie discovered electricity separately. The conductivity and insulation and electrostatic phenomena. The most famous in history is the kite experiment conducted by American scientist Franklin in September 1752, which proved that electricity exists in nature.

In 1831, British scientist Faraday discovered the “law of electromagnetic induction”, the discovery of current magnetic effects, and the proposal of electromagnetic theory, which laid the foundation for the widespread application of electricity and power cord in the later period.

In 1879, the American scientist Edison created the electric light, and the power cord has a wider application prospect in daily life.

Lights Lamps Power Cord

In 1882, Edison created the first power transmission system, in New York, USA, he used copper rods wrapped in jute were placed in a hard pipe of bituminous substance.

Copper Rod power supply cord

In 1889, Franci of the United States created oil-impregnated paper insulated power cables, which are also commonly used high-voltage power cables now.

With the development of technology and demand, the development of power cords is also very rapid.

In the early days of home electrification, people mainly used bare copper wires and used cotton cloth for insulation, and later used rubber or bituminous coated cotton cloth for insulation.

In the 1880s, the invention of vulcanized rubber made the power cord take a big step towards modern development. Vulcanized rubber can be used as cable insulation material. Later, polyethylene and rubber were used as insulating materials. In 1906, an armored cable was manufactured. This cable has good protection to the conductor, but it is expensive.

In the 1950s, people began to use PVC (Polyvinyl chloride) insulated cables to this day.

PVC cable

Note: Some people use aluminum as a conductor to make power cords, which is very dangerous.

The reasons are as follows:

. High resistivity: the resistivity of aluminum cable is about 1.68 times higher than that of copper cable.

. Low strength: the allowable stress of copper at room temperature is 7 ~ 28% higher than that of aluminum. Especially the stress at high temperature, the difference between them is very far.

. No fatigue resistance: aluminum is easy to break after repeated bending, while copper is not. In terms of elasticity index, copper is also about 1.7 ~ 1.8 times higher than aluminum.

. Poor stability and easy corrosion: copper wire is resistant to oxidation and corrosion, while aluminum wire is easy to be oxidized and corroded.

. Small current carrying capacity: due to the high resistivity, the allowable current carrying capacity (maximum current that can be passed) of copper cable with the same section is about 40% higher than that of aluminum cable.

. High calorific value: under the same current, the calorific value of copper cable with the same section is much smaller than that of aluminum cable, making the operation safer.

. Oxidation resistance and corrosion resistance: the connector of copper cable has stable performance and will not cause accidents due to oxidation. The joint of aluminum cable is unstable, and fire accidents often occur due to the increase of contact resistance and heating due to oxidation. Therefore, the accident rate is much higher than that of copper cable.

Types of power cord

There are many ways to classify power cords, which can be divided into computer power cords, light power cords, power cords for small appliances, power cords for generators, etc. according to their use; people can also classify power cords according to different plugs, due to safety requirements , Countries in the world have formulated their own power cord production safety standards and certification systems according to their own conditions. Therefore, there have been many plug standards and certifications in the world. For safety, please buy and use the power cords produced according to safety standards and with safety certificates. The current main plug standards and certification marks in the world are as follows:
