The Characteristics of 50mm Earth Cable

Application:
50mm Earth Cable is suitable for laying at the fixed places. It is widely used in connecting of power device, lighting, daily electrical appliance, instrument etc. with AC rated voltage up to and including 450/750V(U0/U).Earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the earth.
Standard:
The product implement the standards GB/T5023, equivalent to IEC60 227. And it can also be made complying with ASTM, DIN, BS standards etc. In addition, we can design and manufacture the products as t he requirements of customers.
Brief construction:
1) Conductor: Copper or aluminium, Solid
2) Insulation: PVC
3) Number of cores: Single core
4) Other special characteristics: Design and manufacture according t o the requirements of customers.
Service performance:
1) Long-term working temperature: not be higher than 70°C 2) When laying the cable, the ambient temperature should not lower than 0°C
