Building Cables

Mahindayal Building wires are design & manufactured according to various national & international standards such as British standard (BSS), American standard for testing method (ASTM), Indian Railways specification (IRS) Indian Telecom Department (ITD), Telecom Engineering Centre (TEC), Engineers India Limited (EIL) & Bureau of Indian standards (BIS).

Range

Lead Free Flame Retardant (LFFR) : These wires are extruded with special compound with high oxygen and temperature index. The insulation has high resistance and dielectric strength and it is applied over the copper conductor by a dual extrusion using most sophisticated machinery. Mahindayal LFFR wires are non toxic ( 100% lead free).

Flame Retardand Low Smoke & Halogen (FR-LSH) : These wires are extruded with special polymer with special flame retardant, low smoke & halogen emitting and toxic fumes suppressing properties. Mahidayal FR-LSH wires are self extinguish and do not allow fire to spread.

Zero Halogen Low Smoke (ZHLS) : These wires are extruded using specially formulated polymer from the hydrocarbon family of insulants, Mahindayal ZHLS wires disables the release of halogen gas and toxic fumes, the inhalation of which can be fatal for lungs.
