Relemac House Wiring/Domestic cable/PVC Copper Cables
One name in house wires which inspires confidence in consultants, architects and builders today is RELEMAC. One of the most sought-after brands of house wires, Relemac has built up a requtation for commercial foresight and solid integrity. Relemac house wires carry a guarantee that far exceeds the ISI Certification they possess. Tested at every stage and supervised by experienced engineers, Relemac house wire are making a name for themselves in both Indian and world markets.
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 and cords conform to the requirements of table 3 class 5 of IS:8130-1984. The construction of conductor is also made according to customer specification.
Insulation
Relemac House wires are mainly available readily in PVC insulations & also manufactured in various other insulations like, FR PVC / FRLS PVC / HR PVC / ZERO HALOGEN & TEFLON (PTFE) With HR PVC.
PVC Insulation 'Type A' PVC Compound suitable for a maximum continuous conductor operating temperature of 70°C, as referred in IS:694-1990, is insulated over conductor by extrusion process with required thickness of insulation and conforms to all the requirements of IS: 5831-1984.
FR Insulation FR PVC insulation has better fire retardant properties than normal PVC.
FRLS Insulation FRLS PVC insulation provides better fire retardant properties then normal PVC & also emits Low Smoke, in case of fire.
HR PVC Insulation HR PVC Insulation ensures insulation stability at conductor temperature of 85C & 105C, in case of HR85 & HR 105PVC insulation respectively.
ZERO HALOGEN Insulation ZERO HALOGEN Insulation provides better flame retardant properties then HR & FRLS. Zero Halogen required >300 Deg'C temperature to catch fire (with 1% Oxygen).
TEFLON (PTFE) With HR PVC Insulation TEFLON (PTFE) with HR105 PVC are designed for high cost and Sensitive installations where fire from electrical short circuits may cause damage to human life & property. PTFE can withstand,operating temperature from -650C to +2600C.
