Semi-conductive filler rope Introduction
The semi-conductive filler rope is a semi-conductive filling material used in cables which is made by uniformly distributing semi-conductive compound on polyester fiber non-woven fabric, and then twisted. The semi-conductive filling rope has the characteristics of semi-conductivity. Heat resistance and chemical stability, no acid and alkali, no corrosion, high tensile strength and low moisture content.
The semi-conductive filler rope is widely used for cable core filling of power cables. In the process of cable production, in order to make the cable core round, improve the appearance quality of the cable and increase the tensile resistance of the cable, the semi-conductive filling rope is one of the most commonly used filling materials to fill the gap of the cable core.
In addition to the filling function, the semi-conductive filling rope can effectively weaken the electric field strength and reduce the problem of tip discharge during the operation of the cable due to its semi-conductive characteristics.
The semi-conductive filler rope we provide has the following characteristics:
1) Soft texture, free bending, light bending, no delamination powder;
2) Uniform twist and stable outside diameter;
3) Small volume resistivity can effectively weaken the electric field strength;
4) Unloose winding.
Application
It is suitable for cable core filling of power cables.
