2017-04-01
Properties of Silicone Rubber Materials 1. Silicone rubber exhibits excellent heat resistance and cold resistance, with a long-term operating temperature range of –60°C to 180°C. 2. It possesses outstanding electrical insulation properties; its electrical performance is minimally affected by changes in temperature or frequency, as well as by exposure to moisture. Moreover, owing to the inorganic nature of silicone rubber, it demonstrates superior resistance to corona discharge and arc erosion. 3. Silicone rubber exhibits good aging resistance. 4. It also offers favorable oil resistance and solvent resistance. 5. Silicone rubber is fire‑resistant and does not release corrosive gases when burned. Usage Characteristics of High-Temperature Silicone Rubber Cables 1. Long-term maximum operating temperature of the cable conductor: 1
Properties of silicone rubber materials
1. Silicone rubber exhibits excellent heat and cold resistance, with a long-term operating temperature range of –60°C to 180°C.
2. Silicone rubber exhibits excellent electrical insulation properties, with only minimal impact on its electrical performance under varying temperature and frequency conditions or in the presence of moisture. Moreover, owing to its inorganic nature, silicone rubber is resistant to corona discharge and arc erosion.
3. Silicone rubber exhibits excellent aging resistance.
4. Silicone rubber exhibits good oil resistance and solvent resistance.
5. Silicone rubber exhibits fire resistance and does not release corrosive gases when burned.
Operating Characteristics of High-Temperature-Resistant Silicone Rubber Cables
1. Long-term maximum operating temperature of the cable conductor: 180°C.
2. During a short circuit (lasting 5 seconds), the maximum temperature of the cable conductor shall not exceed 350°C.
3. Permissible bending radius of cables: For cables without armor or shielding, the radius shall be no less than 6 times the cable’s outer diameter. For cables with armor or shielding, the radius shall be no less than 12 times the cable’s outer diameter.
4. Cable laying temperature: not less than –20°C. When laying at temperatures below this threshold, the cable shall be preheated.
