Specifications

Power Cable 240 sqmm - 1,2,3,4 Cores Unarmored

 

Kosen Cable manufactures a wide range of Armoured Cables, Armoured Power Cables, Armoured Electrical Cables, PVC Armoured Cables and XLPE Armoured Cables.
 
 

Standard

IEC 60502: Power cables with extruded insulation and their accessories for rated voltages from 1kV (Um=1.2kV) up to 30 kV (Um=36kV).

 

Conductor
Copper conductors are made from high conductivity Copper rods of 8 mm diameter. The rod is drawn to required sizes for the construction of conductors of different areas of cross section conforming to IEC 60502 Standard. Conductors for Power cables with cross sectional area have following configuration
1. Conductors below 6 sq.mm are either solid circular or stranded circular (non-compact) conforming to Table 1Class 1 or Table 2 Class 2 of IEC 502.
2. Conductors of 10 sq.mm and 16 sq.mm are stranded circular (non-compact)
3. Conductors of 25 sq.mm and above are - stranded compact circular for single core unarmoured and armoured  & shaped conductors for multicore unarmoured and armoured.
However, the construction of stranded non-compact conductors can also be made against customer specification.

 

Insulation
XLPE means cross-linked polyethylene or vulcanized polyethylene. The basic material is low density polyethylene. Polyethylene is a thermoplastic material consisting of long chain of hydrocarbon molecules. At elevated temperatures these molecules tend to move relative to one another so that the material becomes increasingly deformable and will eventually melt at the temperature around 110°C.

 

Armouring
Single core cables for use on A.C systems, are armoured with single layer of aluminium wires. Multi-core armoured cables have single layer of Galvanized Steel wire Armour over bedding with left hand lay. Other armours like steel strip, tape can also be provided against customer specification.

 

Outer sheath
For Cables with general purpose PVC insulation, Sheaths are extruded with Black PVC compound of type ST1 and for cables with heat resistant PVC insulation, sheaths are extruded with Black PVC compound of Type ST2 conforming to the requirements of IEC 502.
PVC outer sheath with improved fire performance as per Category Cl and C2 conforming to the requirements of IEC 502 are available against specific requirement.

 

Application

Power Cables (Armored/Unarmored, PVC/XLPE ) are widely used in power systems of rated voltage 1000V and below such as urban communities, office buildings, supermarkets, etc.
