Product Description

China made PE/PVC/XLPE aluminum conductor concentric cable

Power cables for energy supply are used for industry and distribution boards, power stations, house connecting boxes and street lighting as well as control cable for the transmission of control impulses and test data. Overall, where increased electrical and also mechanical protection are required. Those cables are installed in open air, in underground, in water, indoors and in cable ducts. The concentric conductor (C) is allowed to use as PE-, PEN-conductor or as shield. due to the typical construction of concentric conductors it is possible to obtain many more cable joints, without cutting any conductor. In that way the operating reliability is guaranteed.

MATERIAL AND CONSTRUCTION

The cable shall be designed and manufactured in accordance with IEC 60502-1 and Kenya Standard KS 04-1022.

Phase Conductor

1) The phase conductor shall be circular stranded annealed copper conductors (class 2) as specified in KS 04-1022. The phase conductor shall have a left-hand direction of lay.

2) The insulation of the phase conductor shall be red PVC compound specified in KS 04-1022. It shall be applied by an extrusion process and shall be spark tested in accordance with KS 04-1022.

3) The thickness of insulation, determined in accordance with KS 04-1022, shall be not less than the value given in Table 1 of this specification and the smallest of the measured values shall not fall below the value given in the said table by more than (10% + 0.1mm).

Concentric Layer

1) The neutral conductor shall be concentric and shall be manufactured from plain annealed copper wires in accordance with KS 04-1022. The number of wires and the resistance of the neutral conductor shall comply with Table 1 of this specification.

2) The concentric layer shall be applied with a right hand direction of lay.

Oversheath

1) The oversheath shall be an extruded layer of black PVC compound as specified in KS 04-1022. The oversheath shall be spark tested in accordance with KS 04-1022.

2) The minimum thickness of the oversheath shall not fall below the value given in Table 1 of this specification by an amount more than (15% + 0.1mm).

Standard: Low votage polymeric insulated cables for use by distribution and generation utilities. Specification for distribution cables of rated voltage 0.6/1 kV. XLPE insulated combined neutral and earth copper wire concentric cables with copper or aluminium conductors
