Product Details

Normally enamelled copper conductors are used as coil components of various electrical products such as motors / transformers / home appliances / auto electrical components / chokes / AC compressors. Apart from AC compressors all other copper windings undergo secondary insulation coating and curing of the same. The process is called impregnation. The secondary insulation is used to get a firm compact winding, that can withstand vibration and all the copper conductors are held firmly together. The voids in coil are also filled by the secondary insulation. It also prevents direct contact of moisture with the primary (enamel) insulation film. The basic property of secondary insulation (varnish) is to hold the winding together. However for certain applications (where the secondary insulation is not practical) self-bonding enamelled wires can be used. These wires have an outer layer of bondable material which is usually thermoplastic and bonds the wires surfaces with each other once heated to the bonding temperature of the outer layer. Bondable wires, thus, benefits in reduction of cycle time and elimination of process of secondary insulation application / baking / curing cycle etc.

Application

Bondable wires can be used in power tools armature coils, electronics, miniature coils, TV yoke coils, continuous-transposed conductors etc. The bondable layer is applied over variety of primary insulation like polyester, polyester-imide, dual coated and solderable polyurethanes of class 130, 155 and 180.

Company Details

With a modest beginning in 1965 as a small electrical trading shop in the erstwhile city of Bombay, to being India’s leading manufacturer of winding wires today, it has been a very fulfilling journey for RR Shramik. It’s India’s only manufacturer of enamelled copper wires that offers the widest range starting from 0.018 mm to 4.876 mm (SWG 06 – 52) with additional intermediate and mm sizes. It wouldn’t have been possible without the leadership and guidance of Shri. Rameshwarlal Kabra, that we have emerged as the most trusted brand in winding wires. Over the last five decades with the help of our extremely skilled manpower, use of the latest and best technology resources and constantly seeking all round improvement we have ensured that our clients always got an unmatched end-product quality.
Our product line includes sixteen products that broadly fall into five groups i.e. Enamelled Copper Wire (ECW), Enamelled Copper Strips (ECS), Submersible Winding Wire (SWW), Bare Copper Strips (BCS) and Enamelled Aluminium Wire (EAW). Our end products meet all of the well-known Indian and international standards including IS, IEC, JS and NEMA. This provides utmost confidence to our Indian and overseas customers regarding the reliability and consistent quality of products supplied by us.
We operate in the transmission and distribution (T&D) industry, and we are the first choice for large Original Equipment Manufacturers (OEMs) and top electrical companies of India as well as MNCs. We also cater to thousands of small manufacturing and repairing units of electrical equipment in the country.
