Grandlay FR-LSH Wire 4.00mm Black - 180 Meter Jain Electrical House, Tang Narwana, Dharamshala (H.P.) offering Grandlay FR-LSH Wire 4.00mm Black - 180 Meter. The bunched conductors are insulated with specially formulated FRLS PVC compound. The compound is resistant to moisture, oil, alkali and grease and has high insulation and dielectric values. The FRLS properties with high oxygen and temperature index and low acid gas generation help in restricting propagation of flame at high temperatures.In case of fire, the casualties occur due to suffocation and inhaling toxic fumes/gases rather than burns, moreover the dense black smoke reduce visibility, thereby making the evacuation & rescue operation nearly impossible as such the need for FRLS wires arose.The number and diameter of conductor strands are for reference only. Conductor resistance as per IS : 8130 is the governing criteria.
