Description

A kind of nitrile power flexible cable

Technical field:

The utility model relates to the field of power cables, in particular to a nitrile power flexible cable.

Background technique:

Cables are used to transmit electric (magnetic) energy, information and wire products that realize electromagnetic energy conversion. A rope-like cable usually made of several or several groups of wires twisted together with at least two wires in each group. Each group of wires is insulated from each other and often twisted around a center, and the entire outside is covered with a highly insulating covering. layer. Wires and cables mainly include bare wires, electromagnetic wires and insulated wires for electrical appliances, power cables, communication cables and optical cables.

The utility model is suitable for mobile connecting cables with AC rated voltage 0.6/1kV and below, which have special performance requirements such as cold resistance and oil discharge, and is used in metallurgy, electric power, shipbuilding, automobile manufacturing and other industries. The inner side of the layer is provided with a filler, which increases the structural compactness of the cable.

Utility model content:

The purpose of the utility model is to provide a nitrile power flexible cable, which effectively enhances the compactness of the cable structure.

The technical scheme of the utility model is as follows:
