Henan Cableland Cable Co.,Ltd.
Wire and cable are wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in the broad sense are also referred to as cables, and cables in the narrow sense refer to insulated cables, which can be defined as: an aggregate composed of the following parts; One or more insulated cores, as well as their possible cladding, total protective layer and outer protective layer. The cable can also have additional uninsulated conductors.
The main features of power cable products are: extruding (winding) the insulation layer outside the conductor, such as overhead insulated cable, or several cores stranded (corresponding to phase line, zero line and ground wire of power system), such as overhead insulated cable with more than two cores, or adding sheath layer, such as plastic / rubber sheathed wire and cable. The main process technologies include drawing, stranding, insulation extrusion (wrapping), cable forming, armor and sheath extrusion, etc. different process combinations of various products are different.
Cables are products used to transmit electrical energy, information and realize the conversion of electromagnetic energy. When purchasing cables, you need to consider whether the quality of the ABC Cables can meet your needs. The following are several important indicators that need to be paid at... Read more
