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.

Application Crepe Kraft Paper Insulated Copper Cables are mainly used as an insulation in oil cooled transformers, current transformers of type IMB, CT, CVT as leads and shields. 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. Size Range & Types 70 sq mm to 150 sq mm. Copper flexible cables. Specifications FLEXIBLE COPPER CABLES WITH CREPE KRAFT PAPER MULTI LAYERED INSULATION    

TIW, a unique product for small transformers. Three layer extruded coatings of high performance polymer resins gives excellent dielectric properties to this type of winding wires. Unlike enamelled wires, three layers of insulation are extruded over the copper conductor with automated manufacturing process ensure perfect central position of conductor. The conventional enamelled wire winding coils requires insulation between the primary and secondary coils by means of barrier tape or interlayer tape to isolate primary and secondary windings. Since three layers coating is having very high dielectric strength, it has very less creepage factor. This positive feature of TIW serves to downsize switching transformers and promises high production efficiency and cost reduction. Depending on the design, the transformer size can be reduced up to 40% and weight up to 60% as compared to transformers made up of enamelled wires.

Cotton is one of the most useful naturally occurring insulators and is used from ancient time for its also has moderate electrical insulation properties in dry condition. in certain low voltage applications, cotton yarns are used wrapped around insulators., which proved to be long lasting.

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. Application Aluminium is an excellent electrical conductor after copper. The super enamelled aluminium wire can be used to replace the copper enamelled wires with proper design modifications. Mainly it is used in electronic circuits, television degaussing coils and so on for many more applications including washing machine motors, fans and AC compressors. The conductor properties of these wires differ from that of enamelled copper wires. Our products have a smooth surface and a very good elongation.
