New energy, green travel has become a new way of life, and more and more charging piles appear in life, so the standard electric vehicle DC (AC) charging pile cable has become the "heart"···...

In the course of operation, the wire and cable will be heated due to the existence of resistance. The resistance of wire is generally very small, and its heating power can be expressed by formula q=I^2R. Q=I^2R shows that for a wire used···...

1. low resistivity: the resistivity of aluminum core cable is 1.68 times higher than that of copper core cable.2. the ductility is good: the elongation of copper alloy is 20~40%, the electrical conductivity of copper i···...

Cold winter, many construction workers in the installation and installation of wire and cable will find, usually good quality wire and cable products, often appear some line body hard, insulated outer skin shedding damage and other pheno···...
