Taalay Metallics is manufacturing a new range of electrical wires known as PVC/FRLS/HR Insulated Single/Multi core cables, which provides additional safety and security. The wires bear the mark of IS: 694: 1990.
Each wire is fabricated 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 conductor is made of multiple strands of finely drawn copper wires thereby offering greater flexibility, which makes these wires ideal for conduit wiring.
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. All wires are subjected to high voltage spark testing to ensure that no weak spots are there in the insulation.

Fire Resistance Low Smoke cables are used in areas and applications where electrical integrity of the cable has to remain intact for at least three hours, so as to activate and maintain crucial functions such as firefighting, public announcements smoke extraction systems, sprinklers, emergency lighting, evacuation path lightning system, etc. Electrolytic grade copper for conductor to ensure superior conductivity. Insulated with FR-LSH Grade PVC compound formulated and manufactured. In case of fire, FRLS cables have special flame retardant, low smoke emitting and toxic fumes suppressing properties, with improved fire performance for category C-2 as per IS694: 1990 with latest amendments.
