Description

A power control two-in-one high-voltage flat cable

technical field

The utility model relates to the field of cables, in particular to a pull-resistant, wear-resistant and bending-resistant power and control two-in-one flat cable.

Background technique

The power control two-in-one flat cable not only connects the power supply, but also transmits signals, control and communication system control signals. It is widely used in crane equipment supporting, iron and steel, metallurgy, coal, driving and mining industries because of its reliable transmission, softness and durability, and easy maintenance. In recent years, the production of flat cables has gradually increased, but there are still many problems: on the one hand, the bending performance of the cable cannot be achieved, and the flat cable should have a certain bending performance, especially when used in mobile places, the softness of the cable On the other hand, the tensile performance of the cable is poor, especially for cables with control cores. During continuous bending and use, the control cores are easily broken and open circuit faults occur. Tensile flat cables currently on the market generally add several twisted steel wires at both ends of the cable or other suitable positions. During long-term continuous bending and use, as long as one thin steel wire breaks, it may puncture the adjacent cable. The insulation layer or outer sheath of the core will affect the service life of the cable, and will also cause a great waste of resources.
