Smooth inner semiconductive layer
Moderate rotating is essential part in the HV and EHV cable insulation process and does not damage the sensitive Milliken and taped conductors. In MV cable insulation, the cable twister is used for tightening the conductor, thus improving the inner semiconductive layer smoothness.

Description
Cable Twister KLH-HD rotates the cable around its longitudinal axis. The rotation prevents drooping of the insulation and tightens the stranded conductor. The improved conductor quality prevents the intrusion of the semiconductive material into the conductor and improves the quality of the inner semiconductive layer.
By twisting with the twister device the cable is rotated around its longitudinal axis by taking advantage of the movement of the cable and of the friction between the belts of the device and the cable surface. The symmetrical setting of the tilted belts in a certain angle against the centreline of the cable forces the cable into a rotating movement while it is passing through the centricity device.
