What is Silicone Rubber Cable
Silicone Rubber Cable is used as power transmission cable of electric equipments of rated voltage 0.6/1kv or lower in bad environment or that with high temperature. Silicone Rubber Cable has good features of high temperature resistance, flame resistance,radiation resistance, aging resistance, ozone resistance,water proof, freezing resistance, weather resistance etc.
Silicone Rubber Cable Performance for Usage
1: Rated voltage UO/U:600/1000V
2: Working temperature allowed by cable is -60℃～+180℃.
3: Max temperature of cable conductor is no more than 250℃ during short circuit(The longest lasting time is no more than 5s.)
4: Temperature for installing is no less than -20℃.
5: Bending radius of cable as follows:
It is no less than 15 times that of cable outer diameter for cable with single core,It is no less than 12 times that of cable outer diameter for cable with three cores.
Silicone Rubber Cable Technical parameter
1: DC resistance of finished cable conductor at 20℃
shall meet the requirement of GB/T3956 standard. Conductive core DC resistance of finished cable is no more than 0.0184Ω for cable with cross section 1mm2 under the condition that cable length is 1m and temperature is -20℃.
2: Insulated resistance of finished cable insulated
conductor will be no less than 50MΩ for cable with conductive core cross section 50mm2 or lower and 35 MΩ for cable with conductive core cross section 70~185mm2 under the condition that cable length is 1km and temperature is 20℃.
3: Finished cable shall bear A.C voltage test of 3500V under power frequency for 5 minutes without puncture of insulation.
Silicone Rubber Cable Application:
Silicone Rubber Cable Designed for use in environments where prolonged heat resistance is required . Silicone cables are employed where insulations are subjected to extreme changes in temperature. They are heat resistant up to 180 Deg C, intermittently 220 Deg C.
Due to good resistance in all weather conditions these cables can also be employed at temperatures as low as - 60 Deg C. Upon and after combustion a residue of pure silica is produced and the cables continue to function. However, it is usual to provide a glass braid around the cable to prevent a break down of the silica during and after a fire. Silicone cables are low smoke and halogen free and are most suitable for power plants. They have become indispensable in a wide range of industrial sectors, in foundries, steel and hot rolling mills, cooking equipment, cement, glass and ceramic factories, ship and aircraft construction, and oil burners.
