Contact SupplierRELEMAC Welding Cables Double Insulated, Extra Flexible, Orange and Black Jacket
FEATURES
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% |
Cross - Sectional | Max. Conductorb resistance at 200C | Nominal Thickness of sheath | Min. Overall diameter | Max. Overall diameter | Current Ratings Welding Duty Cycle | Non Welding Application | |||
