1. Hard wire and soft wire The core of the hard wire is relatively thick, the general type is BV, which is relatively resistant to short-circuit current and easy to form, but it is difficult to wear the tube, especially the cable of 2.5 square meters or more. The flexible cord is composed of cable... READ MORE
The major difference between irradiated wires and cables and ordinary cables is the different manufacturing processes used.Irradiation technology: It converts power frequency and low-voltage electric energy into high-frequency electric energy, and then obtains high-energy and high-current electron r...
