Welding cables

Features

Based on CENELEC HD 22-6 31, VDE 0282 ,IEC 245-6, IS 473, BS 638-4.
Outstanding toughness & durability.
High resistance to cuts , tears & abrasion.
Resistance to oil , solvents and chemicals.
Excellent ozone and weather resistant.

Applications

Welding : Designed for the secondary (high current) connection to automatic or hand - held metal arc welding electrodes. It is suitable for flexible use under rugged conditions, on assembly lines and conveyor systems, in machine tool and automatically operated line and spot welding machines
Power : Earthing/return leads, power feeds to electrolytic plating process, Busbar connection, transformers, generators, aircraft servicing equipments etc.

Construction

Conductor : High conductivity, bare annealed copper flexible conductor.
Sheath : Double sheathed with specially developed thermoplastic Elastomer (TPR/TPE), outer layer is orange coloured.

Current Rating

The maximum current ratings of flexible welding cables for different duly cycles are based on an ambient air temperature of 25 C and a maximum conductor temperature of 90 C. The percentage duly cycles for various
processes and applications are as follows
1 Automobile Welding : up to 100%
2 Semi-automatic welding : 30% to 85%
3 Manual Welding : 0% to 60%
4 Very intermittent or Occasional Welding : up to 20%

Voltage Drop

When total cable lengths in excess of 15 mtrs., are involved , it may be necessary to use cables of larger cross section to ensure that the voltage drop is not excessive and welding currents are maintained at adequate levels.

Single and Multi core flexible cables

Conductor
Flexible copper conductors are made from high conductivity Copper rods of 8 mm diameter. The rod is drawn to required sizes of fine wires for the construction of conductors of different areas of cross section. Annealed plain copper conductors used in the flexible cables. The construction of conductor is also made according to customer specification.

Insulation

'Type A' PVC Compound suitable for a maximum continuous conductor operating temperature of 70°C, as referred in IS:IS:5831/84, is insulated over conductor by extrusion process with required thickness of insulation and conforms to all the requirements of IS:IS:5831/84.

Laying up

2,3,4,5 Multi core cables are laid up with right hand lay in the outermost layer in the sequence of above core colours. Interstices if required will be covered by non hygroscopic fillers

Sheath

Single core / Multicore are sheathed with 'Type ST1' PVC compound suitable for a maximum continuous conductor operating temperature of 70°C, conforming to the requirements of IS:5831/84. Unless otherwise specified the colour of the sheath will be black.

Packing

Single core / Multicore flexible cables are packed in printed carton boxes in standard lengths of 100m. However cables can also be supplied in longer lengths in strong plywood reels in multiples of 100 mts.

Customer orientation

Against specific requirement and application, WE can offer cables conforming to either customer specification or other National and International Standards
