PRODUCT DESCRIPTION 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. APPLICATION Typical applications for litz wire conductors include high-frequency inductors and transformers, motors, relays, inverters, power supplies, AC/DC converters, communication equipment, ultra-sonic equipment, sonar equipment, television equipment and heat induction equipment. The new innovations in information technology and communication devices have opened tremendous opportunities of usage of litz wires. A latest example can be a wireless mobile charger. TYPES Polyurethane class 130, 155, 180 – Natural / Coloured Polyesterimide class 180 Dual Coated class 200 SPECIFICATIONS Bunching / twisting can be customized as per customer drawing


Uncertainty and higher metal cost in copper have raised the need for alternate conductor metal in various electrical applications. Aluminum being the next good conductive material is most popular as replacement of copper. In certain applications like transformer windings this transition is happening rapidly. The manufacturing of bare aluminum strips is critical process, being the soft metal characteristics of aluminum. At the same time the insulation strength and flexibility have to be excellent to withstand the winding stresses bending / shaping etc. RR Shramik, Jalan amongst other companies has most advanced technique machinery to make the aluminum conductors with precision controls in conductor dimensions and better surface properties. Also, they provide very special attention towards the flexibility and adherence of the insulation film of enameled strips. ADVANTAGES Automated machines for Aluminum strip making enameling Online quality monitoring through blister and pin hole detectors Variety of Class of insulations and Variety in packing spools Stringent test procedures for consistent quality

We offers an industry-leading range of high quality fine and ultra-fine enamelled copper wires. The enamelled wire properties governing proper selection not only require consideration of the end use conditions but system compatibility and ease of use in production. Solderablility, abrasion resistance, bondability, flexibility, insulation builds, etc. Are all typical production and design considerations. Higher temperature requirements and more complex systems dictate the need for knowledgeable selectivity of enamelled wires. In addition to the product featured in this catalogue, we can manufacture custom insulated wires to meet your requirements. APPLICATION Fine and Ultrafine Enamelled Copper Wires are mainly used in Small Transformers, Relays, IgnitionCoils, Transformers& Small Motors
