House Wiring/ Electrical Building Wire
One name in house wires which inspires confidence in consultants, architects and builders today is Relemac Technologies Pvt. Ltd. One of the most sought-after brands of house wires,Electric Wires and Cables Relemac Technologies Pvt. Ltd. has built up a reputation for commercial foresight and solid integrity. Relemac Technologies house wires carry a guarantee that far exceeds the ISI Certification they possess. Tested at every stage and supervised by experienced engineers, Relemac Technologies 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 by using 99.97% pure, electrolytic grade, bright-annealed bare copper with more than 100% conductivity.Copper guarantees higher percentage of electrical energy saving which eventually helps in reducing the electricity bills. 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 Technologies 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.This FR PVC compound has a high oxygen and temperature index. The wires are wadded with a flame retardant (FR) PVC compound, which helps to control the spread of fire even at very high temperature. It also protects against electrical shock and short circuit.
FRLS Insulation
Whenever fire breaks-out in any building/Complex, the burning of wire emanates, the toxic, black smoke, which causes injury and subsequently becomes fatal to the human life. 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.
