Why is bare copper wire the choice in the cable industry?

There are several reasons for this:
In bare copper wires, -some special fine gauge lines are double-grained lines or multi-stranded lines that form a single line together. Hard wires are easier to dry connect, while stranded wires are softer. Wires wrap around a layer of isolation, called an insulator, to prevent conduction between wires or between wires and the environment. This controls the current flow on the wires and the insulation used on most cables
This is a hot plastic, it is a kind of plastic that becomes soft when heated and hard when cold.
-Some cables have insulation material on the wire outskirting, so that the strands in the cable are insulated from the outside, so that the finished cable is protected when subjected to pressure and heat. The roundness of the cable is improved to make it have a uniform shape, and the insulation between the cable core and the environmental electric carrier is also improved. The chip protection is also designed to be flame retardant and resistant. So
The choice of cable type is very important in zonghe routing, and bare copper wire is one of its choices.
Each copper conductor core used in the integrated cabling system is annealed. Heat treatment is a special heating process in the manufacturing process to reduce twisting and vibration stress in a specific environment.
