Fireproof Wire
Step Cables is a pioneering brand among the leading fireproof wire manufacturers in India. Wires and cables are a must for several applications, especially for the transmission and distribution of electrical power. During the fire or electrical hazards or short circuits, these wires and cables are more likely to catch fire, if they are not fireproof. They also emit harmful and toxic gases due to fire which is harmful to both human beings and the environment. To offer protection during the fire breakout, we are manufacturing highly effective fireproof wire. With the help of our engineers and manufacturers, we do in-depth research to manufacture reliable fireproof wire. We make use of the best quality insulation that acts as a fire-retardant material. We also use fire extinguishing compounds when manufacturing these wires to prevent the flames from spreading and causing severe fire accidents. The fireproof wires manufactured by Step Cables, are known to produce less smoke in comparison to normal wires and cables. For emergency places, the wires produced by us are best to use to avoid any kind of fire hazard. Along with the utilization of effective fireproof material, we also make use of state-of-the-art technology for manufacturing unmatched quality fireproof wires. All our fireproof wires have zero halogens and are manufactured using insulation materials like FR PVC / FRLS PVC / HR PVC. Due to the use of these insulation materials, it becomes easy to control the spread of fire. We are known to supply fireproof wire for several places including power plants, manufacturing industries, the retail sector, energy sector, shopping malls, metros, railways, airports, hospitals, and other commercial & residential places.
