Rubber Cables

We are one of the leading manufacturers of a quality range of Rubber Cables. These are fabricated using quality rubber that makes these cables resistant to shock and high voltage. Further, we offer our range of Rubber Cables to our clients as per the specifications of our clients. These cables are widely applied in industrial & ship motor industries. These cables provide brilliant electrical properties and resistance to elevated temperature. Our manufactured rubber cables have high endurance to voltage fluctuations. These cables are resistant to flame and are perfect to be used in electrical equipment and appliances. In case of fire, the nature of its insulation maintains circuit continuity as rubber get burnt and transforms into insulating ash.

Note:
The number of wires is approximate and wire diameter is nominal; they shall be such as to satisfy the requirements of conductor resistance as per Class 5 of IEC 60228 / DIN VDE 0295 / IS 8130 / BS 6360

4 core and 5 core flat cables are available on request.

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. Boilers, Electric Furnaces, Coked Ovens, Driers, Bakeries, Blast Furnaces & High Furnace Generator).

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


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.
