Submersible winding wires, We also offer poly wrapped winding wire commonly known as Submersible Copper Winding Wire. The copper conductor is wrapped with thin polyester film and Biaxial oriented poly propylene (BOPP) films. The most modern plant with sophisticated wrapping heads and in line continuous heat shrinkage furnace is installed to get uniform covering. A complete quality assurance testing by instruments covering all governing standards is available.

Magnet wire, Kraft paper insulation is most commonly used in oil-filled transformers. The plain kraft papers are wrapped in a number of layers around conductors, to acquire the needed insulation strength. However, plain kraft paper has limitations of the flexibility and leads to breakage of insulation in tight shaping of the coils. For this purpose, kraft papers are fabricated or creped. The folds made in creping process, increases the elasticity and flexibility during shaping of coils. It also enlarges the surface area of insulation and absorbs insulating oils resulting in better insulation and heat dissipation during operation.

Enameled wire, Litz wire is a type of cable used in electronics to carry alternating current. The wire is designed to reduce the skin effect and proximity effect losses in conductors used at frequencies up to about 1 MHz. It consists of many thin wire strands, individually insulated and twisted bunched, grouped or braided woven together, as per the specific design and application. This often involves several levels (groups of twisted wires are twisted together etc.). This winding pattern equalizes the proportion of the overall length over which each strand is at the outside of the conductor. The individually insulated copper strands are basically the insulated magnet wires laid in form of cable strands.

Crepe paper has 300% more strength in machine and cross machine direction and hence is more resistant to breakage.It can also take various shapes of the surface being insulated. The cable is wound on FRP Rings, 3 to 12 turns as per transformer application. This is also most suitable as lead wire and terminal wires of PT windings.

We offer a superior range of enamelled copper wires aiming to cater the wide variety of applications in the industry ranging from a common motor rewinding to most critical applications like in automobiles. Enamelled winding wire is a film insulated copper (or aluminium) electrical conductor used in form of coil windings in motors, transformers, generators and other electromagnetic equipments. When wound into coils, and energized, enamelled winding wire creates an electromagnetic field, which is utilized to generate the required output form of energy viz electrical to mechanical (or vice versa) electrical to electrical, and electrical to magnetic energy.

Nylon top coat is used over the regular enamelled copper wires to enhance the mechanical properties of insulation coat. Normal enamelled coating is stressed in coil winding applications like high speed auto winding and auto coil insertions in slots. Nylon top coat exhibits a smooth and tough, slippery surface of top layer of insulation, thus, reducing chances of insulation damage and failures related to mechanical abuse of the thin insulation layer.

Aluminium winding wire, The demand of aluminium magnet wires in many industrial applications has sky rocketed due to unprecedented increase in copper rates. To cater this demand, we proudly declare the addition of super enamelled aluminium magnet wires in the product armory. These are manufactured as per Indian as well International standards and as per the specifications given by the customers. The product is available in different sizes, types and grades of coverings to cater to specific needs for special fields of applications. The latest technology is adopted for manufacturing to offer high quality products.
