this work is being carried out by the vehicle cable working group of the electrical and electronic sub committee of the road vehicle technical committee of the international organization for Standardization (ISO / TC 22 / SC 3 / wg4).

It can be seen from ISO 6722 that the standard for 60 V cables has been revised to meet the requirements of 600 V cables. Because most of its requirements are very general, but the special design required by high-voltage cables is often not considered. ISO 14572 has been similarly revised.

at present, the standardization of high-voltage cables with voltage higher than 600V is a subject of various working groups. the standard number is ISO 17195.

According to the structure of the cable, filling is usually used to ensure the high concentricity of the shielded cable and finally obtain a satisfactory high-voltage cable. the use of tape in the twisted cable core can maintain the flexibility of the cable.
