KS 04-1022 10mm2 16mm2 25mm2 PVC Insulated Single Phase Concentric Copper Cables
1. Concentric Copper Cables Application
The copper concentric cable is used in electric service entrance from the power distribution network to the meter pannel(especially where it is required to prevent electricity theft), and as feeder cable from the meter pannel to the distribution pannel.
This cable an be used in dry and wet places, outdoors or directly buried.It has a maximum operating temperature of 90ºC and rated voltage of 600V&below.
Concentric cable refers to a cable with two concentric conductors, and the conductor and the shield layer share the same axis. It is usually used in distribution networks, current surface boards, meters or circuit panels, which can be placed directly underground or outdoors , Even suitable for dry and humid environments, can support high-bandwidth communications on relatively long lines without repeaters.
2. Concentric Copper Cables Standard
The cable shall be designed and manufactured in accordance with IEC 60502-1 and Kenya Standard KS 04-1022.
3.Copper Concentric Cable Construction
Phase Conductor
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.
Insulation
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.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
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. The concentric layer shall be applied with a right hand direction of lay.
Oversheath
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.
