Extra High Voltage (EHV) power cable is a major back bone of the electric system. The reliability and safety of the electric power transmission system essentially depend upon the quality of the cable. Traditionally Paper Oil Insulation systems have been used in High voltage transmission cables. However, since the advent of synthetic polymer, polyethylene (PE) and cross-linked polyethylene (XLPE) have been used as an insulation material. In most countries the use of polyethylene have been limited to the cross-linked version (XLPE) due to major advantage XLPE has over PE in that it enables the cables to be operated at a higher temperature and results in higher current carrying capacity. Cross-linked polyethylene is also considered to be the material of choice due to its ease of processing and handling as compared to paperoil. In addition, the low dielectric losses of cross-linked polyethylene which become increasingly important with increase in voltage as well as high intrinsic electrical strength makes it the favored material for the range of extra-high-voltage applications. These cables can be designed to meet requirements of international standards such as IEC, ICEA, UL, DIN, VDE, ASNZS, TIS, IS as well as other standards specified by customers.

  EHV Cables The state-of-the-art EXTRA HIGH VOLTAGE (EHV) cable plant with German technology manufactures cables up to 220kV. There are two CCV lines for the same: Single-point-triple-extrusion and sophisticated control and monitoring systems from Machinebau Scholz GMBH & Co. KG Troester Germany Both the above mentioned manufactures are well-known names in CCV LINES TECHNOLOGY and have supplied more than 250 lines 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.

Extra High Voltage Cable Specialty Cables, i.e. Rubber Cables customized to sectors like Wind, Solar, Automobile, Rolling Stock and Railways, Mining, Marine, Crane, Plant, Pilot and Petrochemicals, Offshore and umbilical. In addition to this, the JV also plans to cut down on Speciality Cables’ imports by bringing ‘Technology Based’ product range to India.

The state-of-the-art extra high voltage (EHV) cable plant with German technology manufactures cables up to 220kV. There are two CCV lines for the same: 1. Single- point- triple-extrusion and sophisticated control and monitoring systems from Machine bau Scholz GMBH & Co. KG2. Troester Germany Both the above mentioned manufactures are well- known names in CCV lines technology and have supplied more than 250 lines 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. To control the manufacturing process, the line has 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 al directions, record and analyze the data on line. CCV tube has a Touch Less Sag control system. This system ensures no marks/lines on core unlike the older lines. Facilities like conductor pre-heater, core rotation and DE gasification have also been provided for EHV cables. Computerized control system ensures optimum effeciency, fast start-up, synchornized operations of compound feeds, three extruders, CCV line gas temperature zones, pay off and take up.
