Rubber Cables

In keeping with the company's commitment to technological advancement, elastomer materials such as Polychloroprene ( PCP) , Chloro-Sulphoneted Polyethelene (CSP), Nitrile Rubber /PVC blends, Ethylene Propelene Rubber (EPR), Ethylene Vinyle Acetate (EVA) and Silicone have been specially compounded to meet numerous heat oil and fire resisting requirements. In the recent years Relemac Technologies has also developed special Elastomeric Fire Survival Cables for power , control and instrumentation wiring.
Elastomeric compounds for insulating and sheathing of cables are formulated to meet the requirement of IS 6380, BS 6899, IEC 60502 and other international specification.

Silicon rubber insulated cables

are used in electric utilities such as the generation and transmission of electricity. Long service life under normal environment in Nuclear and conventionally powered generating stations plus safety considerations are the significant factors of these electric appliances. When exposed to fire, Silicon offers circuit integrity, low smoke evolution, and freedom from halogen acids.(For e.g. High Furnaces Generator,Electrical Furnaces,Cokd Ovens, Driers, Bakeries & Blast Furnaces).

Applications:

Steel Mills, EOT Cranes, Airport Lighting, Ships, Nuclear & Thermal Power Stations, Wind Power Mills, Electrical Machines, Textile Machines, Construction Equipments, Turbines.


Welding Cables


Silicon Rubber insulated wires  & cablesRELEMAC 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.
