Main Characteristics:
R70 self fusing silicone rubber electrical tape is a high temperature, arc-and track-resistant tape composed of self-fusing, inorganic silicone rubber with an easy-tear and easy-strip liner, can be used as base tapelayer to cleanly re-enter connections.
Application:
Provide high temperature insulation for way out circle string of wind power generator and turbine generator. Widely use in high voltage power cable industry and aircraft, resistant to electricity arc and track. Can be use to protect the breaker cable connectors and insulation protecting for irregular conductor above 15kV.
Features:
• Materials never affect by different weather and oxygen.
• Resistant to electricity are and track operating temperature: -60~250°C
• Heating shock: 300°C
• Excellent joint character, under layer ease to peel.
