Brief Introduction
A power cable is an assembly of one or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed.
Flexible power cables are used for portable devices, mobile tools and machinery.
Specifications and Standards
IEC60502,and BS6346, VDE, AS/NZS, UL,etc or as customer's request.
Construction
| Conductor | Compact Stranded Copper Conductor, Class 2 as per IEC 60228 |
| Circular solid Copper Conductor, Class 1 as per IEC 60228 | |
| Insulation | XLPE(Cross-linked polyethylene) |
| Filler | PP Filler |
| Wrapping Tape | Non woven |
| Inner Covering | Extruded PVC |
| Armour | Steel Wire |
| Overall Sheath | Termite Resistant PVC |
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.
