Applications
Used for power transmission and distribution line with voltage rated at 35kV and below.
Compared with PVC Insulated Power Cable, xlpe power cable 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.
