Control cable and preparation process thereof

Abstract

The invention discloses a control cable and a preparation process thereof, and relates to the technical field of cables, the control cable comprises an outer sheath, a steel wire armor is wrapped in the outer sheath, an anti-wear layer is wrapped in the steel wire armor, a cabling constraint layer is wrapped in the anti-wear layer, and a Y-shaped separation layer is fixedly connected in the cabling constraint layer. The Y-shaped separation layer divides the cabling constraint layer into three filling chambers, and each filling chamber is internally provided with an alloy lead sleeve. Accordingto the control cable and the preparation process thereof, the Y-shaped separation layer is arranged in the cabling constraint layer, then the cabling constraint layer is divided into three filling chambers, and the three groups of wires are placed in different chambers, so that the problem of mutual penetration among the three groups of wires when the sheath of the control cable is damaged and water enters the control cable along a fault point is avoided; and the other two groups of wires are protected to a certain extent, so that the service life of the control cable is prolonged, and the maintenance cost of the control cable is reduced.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a control cable and a preparation process thereof. Background technique [0002] Control cables are PVC insulated and PVC sheathed control cables suitable for industrial and mining enterprises, energy and transportation departments, and for controlling and protecting lines with AC rated voltage below 450 / 750 volts. Common faults in control cable lines include mechanical damage, insulation damage, insulation damp, insulation aging and deterioration, overvoltage, cable overheating faults, etc. [0003] Wet control cable insulation is one of our common failures. There are many reasons for insulation to be damp. When a fault such as breakdown occurs for some reason, the accumulated water in the cable trench will enter the interior of the control cable along the fault point. When such an accident occurs, the insulation of the control cable will be severely damaged, which will also cau...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a control cable and its preparation process, which solves the problem that several groups of wires in the existing control cable are wrapped in the same cable binding layer, and the sheath of the control cable is damaged. Water will enter the inside of the control cable along the fault point, which will cause mutual penetration between the wires, and then the wires in the control cable will be damp, which will seriously damage the insulation of the control cable and affect the service life of the cable. question
