Silicone Rubber Insulation Electrical Motor Leading Wire Silicone Rubber Insulated Cable Silicone Rubber Insulation Wire Silicone Rubber Insulation High-voltage Installation Wire Product Features: H-grade cable insolating wrapping makes current intensity increase one time or reduce section and weight of wire and the whole cable in large range. Substituting silicon rubber matrix for organic vulcanizate insolating materials in electromotor can increase its using span life by 10 times or increase its power by 30%-40% in the same conditions of size and weight. In high-voltage and high frequency cable and wire, silicone rubber matrix cannot be substituted.  Wire applies for alternating rated voltage: include 1140V, F-grade and H-grade insolating motor connecting wire. Recommended applications: Because silicon rubber elastic body has excellent dielectric properties in wide frequency and temperature range, and also has  good performances of cold resisting,heat resisting and moisture-resisting, this   product is widely used in electrical engineering, wireless  technology and cable industry.
