Silicone rubber is a preferred material for cable accessoriesdue to its excellent mechanical and electrical properties.For more than 40 years silicone has been used successfullyas high-quality electrical insulation for voltages upto 400 kV. Silicone rubber features high quality electricalinsulation, superior corona and tracking resistance,combined with high elasticity. It facilitates multi rangeapplication, where one silicone rubber body can beused for various conductor cross sections. Optimalflexibility ensures easy assembly of the accessories.
