Last week, a project owner send BV inspector to come our factory to inspect conductors including ACSR 70/11, ACSR 50/8 and ACSR7/2.5-35.

The atomic number of copper is 29, which belongs to transition metal, the density is 8.92g/cm3, the melting point is 1083.4℃, and it has good thermal and electrical conductivity. However, the surface of metal copper chemically reacts with oxygen in humid air to form Cu2(OH) 2CO3, or patina, usually shows that the surface of copper oxide is black in cable manufacturing plants. It is the existence of this phenomenon of surface oxidation of copper conductors that plagues many cable companies.

What are cable wires made of? Since electrical wires help current flow efficiently, they need to be made of highly conductive material and insulated properly.

Perhaps you have noticed that the recent “dual control of energy consumption” policy of the Chinese government has had a certain impact on the production capacity of some manufacturing companies, and the delivery of orders in some industries has to be delayed.

The structural components of wire and cable products can generally be divided into four main structural components of wire, insulation layer, shielding and protective layer, as well as filling components and tensile components. According to the requirements and applications of the product, some products have a very simple structure, with only one structure of wires, such as overhead bare wires, catenary wires, copper-aluminum busbars (bus bars), etc.; the external electrical insulation of these products depends on installation and laying Use insulators and space distance (that is, use air insulation) to ensure.
