High tear resistant silicone rubber cable performance: High tear resistant silicone rubber cables are suitable for high-temperature and mobile industries such as steel, smelting, power plants, coking plants, aviation, metallurgical machinery, petroleum, chemical, etc. In power, control, and monitoring circuits with a rated voltage of 0.6/1KV and below. High tear resistant silicone rubber cables have excellent characteristics such as high temperature resistance, flame retardancy, radiation resistance, aging resistance, ozone resistance, softness, and waterproofing, as well as good cold resistance and weather resistance. It has better mechanical properties, is more wear-resistant, tensile resistant, and superior insulation performance than ordinary silicone rubber cables. Long service life.
Performance of high tear resistant silicone rubber cables:
1. Rated voltage: ≤ 0.6/1KV.
The allowable working temperature range for 2 cables is -60 ℃ -+180 ℃.
The high temperature of the cable conductor during a short circuit shall not exceed 250 ℃.
The laying temperature of 4 high tear resistant silicone rubber cables should not be lower than -20 ℃.
The bending radius of a 5-high tear resistant silicone rubber cable is as follows: the bending radius of a single core cable shall not be less than 15D of the outer diameter of the cable; The bending radius of a three core cable (D-cable outer diameter) shall not be less than the cable outer diameter of 12D.
Technical parameters of high tear resistant silicone rubber cable: 1. DC resistance of finished cable conductor at 20 ℃: should meet the requirements of GB/T3956 standard. The DC resistance of finished cable conductor core, converted to cable length of 1m, nominal cross-sectional area of 1mm2, and temperature of 20 ℃, should not exceed 0.0184 Ω.
2. Insulation resistance of finished cable insulation core: The insulation resistance of finished cable insulation core, converted to a cable length of 1KM and a temperature of 20 ℃, should not be less than 50M Ω for conductive core sections of 50mm2 and below, and should not be less than 35M Ω for 70-185mm2
3 finished cables should undergo a power frequency AC test voltage of 3000V/5min, with no insulation breakdown.
