More safety, more performance

For manufacturing of high-voltage grade silicone insulators and surge arresters TERRA offers a special range which consists of high-voltage grade liquid silicone rubbers (LSR), liquid colourants for silicone rubbers and other complementary additives that guarantee high efficiency and high effectiveness.
SILASTOSIL® LR 2000 line high-voltage grade liquid silicone rubbers are used with liquid injection molding method and provide excellent processing properties and high tracking and arc resistance. They are noted for their superior mechanical and electrical properties:
- low viscosity, very good flowability
- low temperature cure
- outstanding dielectric properties
- excellent tracking and arc resistance
- sustained hydrophobicity
- high tear strength
- outstanding ageing behaviour and weather resistance
- high stability and flexibility at low temperatures
- ease of processing
- rapid vulcanisation
- excellent adhesion (good adhesion to other LSR)
- superior insulating
- high UV-resistance
- easy pigmentable with liquid colour pastes
- comply with RoHS
SILASTOSIL® LR 2000 line high-voltage grade liquid silicone rubbers provide many critical benefits and advantages for energy and power transmission lines and high-voltage electric networks:
- highly hydrophobic performance
- very good weatherability
- high erosion-resistance
- ease of installation
- improved tracking, arc and tear resistance
- improved electrical insulation
- high protection against environmental stresses
- extended component service life
- reduce of power loss
- reducing of total system costs
- improved safety and security
- reduced maintenance costs
- extended service life
- improved reliability
