Bharat Insulation Company specializes in the manufacturing, supply, and export of a wide range of paper-covered and polyester film-covered copper & aluminium conductors, designed to meet the stringent demands of the electrical and transformer industries. Our conductors are available in both round and rectangular profiles, made from high-conductivity copper & aluminium, and insulated with premium materials such as electrical-grade kraft paper, polyester film, Nomex, mica glass, and aromatic polyimide films.
Offered in thermal classes ranging from 105°C to 240°C, these conductors comply with key industry standards including IS:13730, IS:7404, IS:6162, MW-60, and MW-61. They are ideal for use in motors, transformers, reactors, and other high-temperature electrical equipment. With customizable insulation grades such as DPC, TPC, MPC, and A1 to B5, and cross-sectional dimensions ranging from 1.00 mm² to 100.00 mm², we ensure high reliability, durability, and performance across all applications.
These conductors are bare copper & aluminium wires wrapped with insulating materials such as kraft paper, polyester film, or high-grade polyimide films. Their primary function is to prevent short circuits, manage heat build-up, and maintain stable electrical performance over extended periods.

Paper covered conductors are mainly used in transformers, reactors, and motors, where high electrical insulation and thermal resistance are essential.
Yes, polyester film insulation wires are suitable for medium- to high-voltage winding applications, especially where thermal endurance and mechanical durability are required.
PCCA conductors: Paper Covered Copper Aluminium Conductors
PICC wires: Paper Insulated Covered Conductors – primarily copper-based
Both are designed for thermal insulation and dielectric performance but vary in base metal and specific applications.
Absolutely. At Bharat Insulation Company, we offer customised conductor dimensions and insulation grades, including dual insulation copper conductors, to meet unique design requirements.
