Application:
This type of product is used for power transmission and distribution line with voltage rated at 35kV and below. In comparison with PVC Insulated Power Cable, it boasts not only characteristics of excellent electricity, mechanism, heat and aging-resistant, environment stress-resistant and chemical corrosion-resistant, but also simple structure, light weight, no restriction by laying drop, and high temperature allowance for long-term working.
 
For laying indoor, tunnel, underground and canal, for laying in shaft, water under ground and large difference of level.
