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.
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.
| Cable diameter, max. | 140 mm |
| Set angle of belts, max. | ±9.5 ° |
| Weight | 1000 kg |
Exact values depend on the assembly.

When thinking about sustainability in the cable industry, Maillefer considers where we can have the most impact on carbon footprint. Our own actions as an equipment provider are clearly modest compared to the effects we can have on the cable manufacturing end. In cable production, the materials processed during the extrusion phase easily represents 95% of the carbon footprint generated. This is because cable making consumes much material. At Maillefer, we can have the biggest impact by helping our cable-making customers achieve their sustainability goals. Our shared goal is to make more with less. Read more
