Ultra Safety &
Performance

NISHAD Heat Shield is a flame retardant PVC insulated house wire with 99.97% pure copper. It uses RLSH (Reduced Low Smoke Halogen) technology and triple layer protection, ISI certified under IS-694 for maximum fire safety in residential and commercial buildings.

UltraGuard uses ZHFRLS with EBEAM cross-linking; Heat Shield uses flame retardant PVC with RLSH. UltraGuard suits high-safety environments while Heat Shield offers excellent fire protection at a lower price. Both feature 99.97% pure copper and triple layer protection.

Yes. All NISHAD wires are ISI certified under IS-694 by the Bureau of Indian Standards (BIS). The company also holds ISO 9001:2015 certification and CMIL approval (License No. CMIL-0992092).

NISHAD wires come in 0.75, 1.0, 1.5, 2.5, 4.0, 6.0 and 10.0 sq mm sizes. Both UltraGuard ZHFRLS and Heat Shield PVC variants are available across all sizes.

99.97% pure copper gives better conductivity and less heat buildup than CCA wires. This means improved energy efficiency, longer wire life and lower electricity bills.

Flame retardant insulation self-extinguishes when the fire source is removed. This prevents fire from spreading through wiring. Both Heat Shield and UltraGuard wires are flame retardant.

EBEAM (Electron Beam) cross-links insulation at the molecular level. This makes the wire more heat resistant and mechanically stronger, withstanding higher temperatures without melting.

Indrason is a wire brand under NISHAD Cables offering FRLSH PVC insulated triple layer multistrand FR cables. It features 99.97% pure copper, ISI certification and ultra protection technology for homes, offices and industrial use.

Both are made by the same manufacturer. NISHAD UltraGuard and Heat Shield are premium lines, while Indrason offers FRLSH flame retardant wires at competitive pricing. All share 99.97% pure copper, triple layer protection and ISI certification.

For house wiring in India, fire resistant wires with ISI certification (IS-694) and pure copper conductor are recommended. Use 1.5 sq mm wire for lighting circuits, 2.5 sq mm for power sockets, and 4.0 sq mm or above for heavy appliances like AC, geyser and water heater. NISHAD UltraGuard (ZHFRLS) and Heat Shield (FRLSH) wires meet all these requirements with 99.97% pure copper and triple-layer protection.

FR (Flame Retardant) wire self-extinguishes but produces smoke. FRLS (Flame Retardant Low Smoke) reduces smoke emission. FRLSH (Flame Retardant Low Smoke Halogen) further reduces toxic halogen gases. ZHFRLS (Zero Halogen Flame Retardant Low Smoke) eliminates all halogen content, making it the safest option for enclosed spaces. NISHAD UltraGuard uses ZHFRLS technology while Heat Shield and Indrason use FRLSH grade.

For air conditioners (1.5 ton), use 4.0 sq mm wire. For geysers and water heaters, use 4.0 sq mm wire. For washing machines and refrigerators, 2.5 sq mm is sufficient. For induction cooktops and microwave ovens, use 4.0 sq mm. Always use ISI certified fire resistant wire with pure copper conductor for heavy appliance circuits.

Check for the ISI mark (IS-694) printed on the wire insulation at regular intervals. Verify the BIS license number on the manufacturer's website. Original wires have the brand name, size, and voltage rating printed clearly. Pure copper wire has a bright reddish color — if the conductor looks dull or yellowish, it may be copper-clad aluminium (CCA). NISHAD wires carry ISI certification and CMIL approval (License No. CMIL-0992092).

NISHAD house wire prices per 90-metre coil: 1.5 sq mm Heat Shield wire starts at ₹3,848, 1.5 sq mm UltraGuard ZHFRLS at ₹4,630. For 2.5 sq mm, Heat Shield starts at ₹6,146 and UltraGuard at ₹7,510. Indrason FRLSH wires are available at competitive pricing. Prices vary by dealer — use the Get Quote button for current bulk rates.
