1. Single- point- triple-extrusion and sophisticated control and monitoring systems from MachinebauScholz GMBH & Co. KG
2. Troester Germany
Both of the above mentioned are EHV and high voltage electrical cable plant control instrument suppliers. They are well- known names in CCV lines technology segment and have supplied more than 250 lines the world over. The triple extrusion and DCDC process ensure contamination-free cores. All three layers are well- bonded and the core has very less eccentricity and ovality. The insulation itself is free of micro voids and has negligible moisture content.
Manufacturing EHV Cables
To control the manufacturing process of these high voltage electrical cables, the lines have been provided with many computer-monitored instruments and servo controls. Some of the important systems are:
X-ray non-touch sensors of SIKORA make for thickness and dimensional control. This system continuously measures the dimensions of insulated cores. The unit has the capability to measure multi-layer dimensions in all directions and record and analyse the data on line.
The CCV tube has a Touchless Sag control system. This system ensures no marks/lines on the core unlike the older lines. Facilities like a conductor pre-heater, core rotation, and DE gasification have also been provided for EHV cables.
Computerized control system ensures optimum efficiency, fast start-up, synchronized operations of compound feeds, three extruders, CCV line gas temperature zones, pay off, and take up.
KEI has added EHV Cables in multicore i.e. 3 core cables up to and including 66 kV, to its list of products.
KEI Industries Limited, known for its unique product range across the world is one of the leading wire and cable manufacturers in India. KEI manufactures high and low tension cables (EHV, HT & LT), control and instrumentation cables, house wires, power cables, stainless steel wires, and electrical cables. Its unique product range of wires and cables is known pan India and across the globe KEI has also been the recipient of the prestigious Super brand award for five years in a row (2011-2016) further strengthening the consumers trust and bench marking the company as a reputed wire and cable manufacturers in India. To follow the present demands of the market, KEI set foot into the manufacturing of EHV cables up to 400kV in collaboration with Brugg Cables, a century old Swiss company.
