EVERYTHING YOU NEED TO KNOW ABOUT ELECTRICAL CABLES What is an electric cable? An electric cable is one whose purpose is to conduct an electric current. Generally, the electrical cable is usually made of copper due to its high conductivity of aluminum with less conductivity but cheaper than copper. What is a unipolar, bipolar, multipolar cable …? We start with the […]

Copper Wires and Copper conductors

Electrical cables as conductors of electricity, copper and aluminum cables, insulation of electricity cables, China copper wires manufacturer. Copper conductors We all know copper cables, conductors of electricity in our house, or our electrical appliances. Electrically conductive wires are usually made of copper or aluminum, although they can also be made of other metals or alloys. Copper […]

What cable section should I choose for my electrical installation?

6 types of guides for electrical wiring An important part in the development of residential electrical installations is wiring; There are many ways to get cables from register to register; In cases where the sections are short and with few bends, the cables can even be inserted directly as long as 40% (or more) of the tube area […]
