When we want to understand the various properties of wire and cable, we must have a general understanding of the wire and cable itself. What are the main raw materials for the wire and cable? Let’s take a look at the cable construction in general purpose:

What material is the wire and cable made up of?

1, copper wire:

The copper wire produced by the continuous casting and rolling process is called a low-oxygen copper wire using electrolytic copper as a raw material; the copper wire produced by the upper drawing method is called an oxygen-free copper wire.

The low oxygen copper wire has an oxygen content of 100 to 250 ppm, a copper content of 99.9 to 9.95%, and a conductivity of 100 to 101%.

The oxygen-free copper wire has an oxygen content of 4 to 20 ppm, a copper content of 99.96 to 9.99%, and a conductivity of 102%.

The specific gravity of copper is 8.9 g/cm3.

2, aluminum wire:

The aluminum wire used for the wire is subjected to annealing and softening. Aluminum wires used as cables are generally not softened.

The electrical resistivity of aluminum for wire and cable is required to be 0.028264 Ω·mm 2 /m, and the specific gravity of aluminum is 2.703 g/cm 3 .

3. Polyvinyl chloride (PVC):

Polyvinyl chloride plastic is based on polyvinyl chloride resin and mixed with various compounding agents, such as antioxidants, antioxidants, fillers, brighteners, flame retardants, etc., and its density is 1.38~1.46g/cm3. about.

Characteristics of PVC materials:

Excellent mechanical properties, chemical resistance, no flame retardancy, good weather resistance, good electrical insulation properties, easy processing.

Disadvantages of PVC materials:

1 A large amount of toxic fumes are emitted when burning;

2 Thermal aging performance is poor.

Polyvinyl chloride is divided into insulating material and sheathing material.

if the good material is inspected well before production, it would make half preparation for quality power cable, for its production also plays close role. skilled worker under strict production rule is very necessary.

xinchang cable inspector are on work 24 hours to make sure cable quality meet standard requirements.

its production from the very beginning of metal melting, then conductor rod to conductor wire, then cable....
