HT Underground Armoured Electrical Cable AL/XLPE/CTS/PVC/STA/PVC 8.7/15KV 3x300SQMM
Application
Used for power transmission and distribution line with voltage rated at 35kV and below.
High and Medium voltage power cable for static application in ground, within and outside facilities, outdoor, in cable canals, in water, in conditions where cables are not exposed to heavier mechanical stress and tensile strain.
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.
