0.6/1kv Pvc Insulated Single Phase Concentric Aluminum Cables 10/16/25/35mm2

 

1. SCOPE

This specification is for PVC insulated single phase concentric cables with circular stranded Aluminum conductors for operation up to and including 1000 Volts between phases and 600 Volts to earth. The cable shall have a central phase conductor insulated with red PVC and concentric layer comprising bare aluminum wires (combined neutral-earth conductor) and out sheath in black PVC.

3. MATERIAL AND CONSTRUCTION

3.1. The cable shall be designed and manufactured in accordance with Kenya Standard KS 04-1022 and the requirements of this specification.

 

3.2. Phase Conductor

 

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

 

3.2.2 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.

 

3.2.3 The thickness of insulation, determined in accordance with KS 04-1022, shall be not less than the value given in Table 2 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).

 

3.3. Concentric Layer

 

3.3.1 The neutral conductor shall be concentric and shall be manufactured from plain annealed aluminum wires in accordance with KS 04-1022. The number of wires and the resistance of the neutral conductor shall comply with Table 2 of this specification.

 

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

 

3.4. Oversheath

 

3.4.1 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.

 

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

4 .STANDARD SIZES AND CHARACTERISTICS

The characteristics of the cables shall comply with table 2.
