valid until: 07 Dec 2023date published: 07 Dec 2022

Spring cable is a kind of equipment connecting line that uses scalability to work. It is an electrical connection used to control the movement of mobile equipment. It can rebound quickly in a short time and is widely used in mobile equipment such as automobiles, charging equipment, automatic machines, meters, etc; It is used in Europe, America and some domestic high-end customized products.

The spring cables of this series of products are mainly used in charging systems conforming to GB/T 18487. 1-2001. They are connected with connecting devices specified in GB/T 20234. They operate at different voltages and frequencies, and may also include lower voltage levels and communication signals. The conductors are Class 5 or Class 6 conductors in GB/T3956.
