So that’s how I understand what is an iec cable?
Now I want to turn it over to you: Through my article, you understand how to choose and what are the standards?
Do you have a different point of view with the electrical outlet? Or any other questions?what is an iec cable？
Let me know by leaving a quick comment below right now.
IEC is an authoritative international standardization and conformity assessment organization in the world, and it can be said that the current rules and certification system in the electronic field are established by IEC.
China is a permanent member of IEC, a member of all four international certification systems of IEC, and an active member of 203 technical committees and subtechnical committees of IEC.（what is an iec cable） It can be said that the IEC organization and the Chinese cable manufacturing industry are a win-win cooperation relationship, and China plays a pivotal role in IEC.

So, what is an IEC cable?IEC standards provide a set of universally recognized international standards for the entire industry, but the level of economic development varies between countries in each region of the world, and the development of the cable industry is more uneven; for cable standards, the requirements of each country and region are different.what is an iec cable？
For example, in the European Union, the European region is the most developed country, then the European Union, composed of European countries, its standard-setting will not be low, the European standard for cables to be higher than the IEC standard, in Europe, there is a special body in charge of European cable standards:
the European Electrical Association, which through the development of European standards and the release of harmonization documents to promote the European member states to achieve a very fast rate of standard harmonization, which also indirectly promotes the This has indirectly contributed to the formation of European integration. At this point, you should know what an IEC cable is?
However, the development of standards between regions and countries is not uniform and is not conducive to the establishment of a unified system; although many regional countries still have their own standards in force, in recent years, （what is an iec cable）with the trend of international integration, these standards are being integrated with each other, the future, the global market is expected to unify the use of a set of standards.
If you have understood what is an IEC cable?, then you should also understand some IEC specifications.
About the cable accessories, IEC specification
Cable accessories are one of the essential and important supporting equipment in the electric, electric power, and light industry, from ultra-high voltage transmission lines to household electrical products. It has wide varieties, the scale of use is quite extensive, domestic manufacturers amount to thousands of enterprises, and many products are included in the national electrical product safety certification product scale. With the progress of science and technology and the increase in social demand, in recent years, China has made a lot of wire and cable national specifications revised.
Cable accessories are one of the essential and important supporting equipment in the electrician, electric power, and light industry, from ultra-high voltage transmission lines to household electrical products; in our life, every link can not be separated from the cable accessories products. It has wide varieties, the scale of use is quite extensive, domestic manufacturers amount to thousands of enterprises, and many products are included in the national electrical product safety certification product scale.
With the progress of science and technology and the increase in social demand, in recent years, China has made a lot of wire and cable national specifications revised. In general, the applicable specifications for cable accessories are mainly three levels (IEC norms, national norms, and occupational norms).
The first level of cable accessories standards: IEC specifications
IEC60859 “Additional voltage 72.5kV and above gas-insulated metal closure switch cable coupling device
IEC61442 “Additional voltage 6kV (Um=7.2kV) to 30kV (Um=36kV) power cable accessories test methods
IEC60502 “Extruded insulated power cables and their accessories for additional voltages above 1kV (Um=1.2kV) to 30kV (Um=36kV)
IEC60840 “Test methods and requirements for extruded insulated power cables and their accessories from an additional voltage of 30 kV (Um=36 kV) or more to 150 kV (Um=170 kV)
IEC62067 “Power cable systems for extruded insulated power cables and their accessories for additional voltages above 150 kV (Um=170 kV) to 500 kV (Um=550 kV) – Test methods and requirements
IEC60055 “Additional voltage 18/30kV and below paper insulated protective metal jacket (with copper or aluminum conductors, but does not include pressurized gas and oil-filled cables)” Part 1 “Cable and accessories test” in Chapter 7: type test of accessories.
Second is the implementation of cable accessories standards.

1, the site must be installed correctly, error-free, and strictly comply with the process operating procedures; the power test is correct before putting it into operation.
2, cable accessories are necessary and reasonable design, the performance of the factory cable accessories with components, parts or materials to meet the requirements of the corresponding specifications; pass the inspection before leaving the factory.
3, is the cable accessories include a section of the cable, so the cable body insulation quality is necessary to be reliable; otherwise, it will also directly affect the reliability of the performance of cable accessories from the carrier to eradicate the possibility of the onset of problems.
