Welding Cables

 

RELEMAC Welding Cables Double Insulated, Extra Flexible, Orange and Black Jacket

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 converyor 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	upto 100%
2	Semi-automatic welding	30% to 85%
3	Manual Welding	0% to 60%
4	Very intermittent or Occasional Welding	upto 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.
