Stress Control Tubes

Stress Control Tubes Stress is manufactured from Radiation Cross -linked Polymeric material. The specially designed chemical formulation and manufacturing technology allows it to control High Electrical Stress present at Insulation Screen Terminals and Power Cable Joints upto 36KV.
