Key Features

Maximum Torsional Rigidity – Reinforced with Vulcanized Polyester Fibers

The incorporation of supporting polyester fibers vulcanized directly into the cable sheath represents a breakthrough in reeling cable design. This innovation provides maximum torsional rigidity, preventing cable twist and ensuring consistent electrical and optical performance even under high-torque conditions. The vulcanization process creates a permanent bond between the polyester fibers and the sheath material, eliminating the risk of separation that can occur with conventional reinforcement methods.

High Electric Strength – Special EPR Insulation for HV Applications

The cable's exceptional electric strength is achieved through the use of specialized ethylene propylene rubber (EPR) insulation materials applied using advanced sandwich processing techniques. This construction method ensures uniform insulation thickness and eliminates air pockets that could compromise electrical integrity. The result is a cable capable of handling voltage ratings from 6/6 kV up to 12/20 kV, with higher voltage grades available upon request.

Easy Termination – Semiconducting NBR Outer Sheath

The outer sheath construction using semiconducting and cold-strip nitrile butadiene rubber (NBR) facilitates rapid and reliable termination procedures.
