The high-current wire is composed of two parts: the wire and the terminal, and the cold die-casting technology is used between the terminal and the wire, so that the wire and the terminal are perfectly combined and will never fall off. High-current wires are widely used in high-voltage and high-current tests of electric power, and can also be used for high-current instruments and equipment, high-current test devices, electric power laboratories, load tests, and connecting wires in AC and DC power distribution cabinets.

According to the national standard, the general high-current wire can be calculated according to the safe ampacity of 5A-8A per square millimeter of wire, if it is running for a long time, it is recommended to calculate the safe current carrying capacity of 3A-4A per square millimeter of wire.
