Contact SupplierPVC insulated non sheathed single core cables for internal wiring.
IS ideal for wiring solutions in multi-storied buildings, hotels, hospitals, commercial establishments and residential complexes. It is shielded by a specially formulated flame retardant PVC compound. During fire, ordinary PVC emits black smoke and toxic fumes which are acidic in nature. This impairs visibility and hampers rescue operations. FRLS insulation retards spread of fire and emits minimum smoke and toxic gases, thereby reducing the risk of injury.
Manufactured from bright-annealed 99.97% pure bare copper.
Insulation:Operating Temp:
-15°c to maximum +70°C
