Heat resistance and electrical insulation of silicone rubber

2014-03-20 1242

With the advancement of skills, the operating temperature of various electrical equipment increases, and silicone rubber wires and cables are operated at high temperatures of 150-200 degrees Celsius for long periods of time. Silicone rubber wire and cable can withstand 90% current overload compared to general wire and cable insulation materials. Silicone rubber wires and cables, even if burned, generate nonlinear coefficients that are conductive. Therefore, silicone rubber insulated cables wrapped in fiberglass fabric can be completely destroyed when the insulators are still functional. Equipping high-voltage electrical equipment often generates ozone, and silicone rubber has strong resistance to ozone. Silicone rubber wires and cables have a long service life and are very safe.

Silicone rubber has excellent electrical insulation function, and in addition, it has outstanding hydrophobicity and hydrophobic mobility, making it widely used in the production of lightning arresters and composite insulators.

The molecular configuration mechanism of hydrophobicity: Silicone rubber is a spiral, and all its organic bases organize the outer edge of the spiral molecular chain, which makes the entire silicone rubber molecule and carbon silicon bond organically based, giving silicone rubber outstanding hydrophobicity.
