Design & Quality
Design of a cable is highly complex owing to the two components, the current carrying copper conductor and insulation to isolate the conductor from each other and as well as surroundings.These two form the core of the cable. The copper and the PVC of TARUN FR PVC Wires and Cables meet high quality standards. TARUN FR PVC Wires and Cables are ISI marked and confirm to IS 694:1990 standard.

- Electrolytic Grade copper having 99.96% purity & maximum conductivity to ensure minimum power losses & maximum safety.
- Uniformly bunched copper wires of uniform diameter that makes stripping & crimping of wires easier & minimizes losses.
- Indigenously developed PVC compound formulated from fines ingredients is produced in-house. High thermal stability & insulation resistance makes it suitable for use in Indian environment.
- Double insulation,with primary insulation from virgin PVC & the Secondary insulation from high tensile vergin PVC ensures the strength of the cables.
