Annapurna Winding Wires Pvt. Ltd. (AWW), a premier unit of the Rathi Group, manufactures high-conductivity Super Enameled Copper Winding Wires (SWG 8 to 42), strips, and earthing solutions engineered for transformers, motors, and high-voltage power applications.
Since 1984 A.D. (2040 B.S.), we have led Nepal's electrical conductor and magnet wire industry with state-of-the-art multi-die drawing machinery and zero-defect quality control.
As the first winding wire plant established in Nepal, our Biratnagar manufacturing complex guarantees uniform dielectric enamel coating, excellent flexibility, and zero pinhole failures.
Raw materials consist of continuous cast electrolytic copper rods imported directly from accredited global refineries and synthesized with high-grade polyester and polyurethane enamels.
Occupational safety, worker health, and environmental compliance are top priorities. Our operations adhere strictly to ISO 9001:2015 and ISO 14001:2004 environmental management protocols.
Annapurna Winding Wires Pvt. Ltd., an integral manufacturing unit of the Rathi Group, was established in 1984 A.D. (2040 B.S.) as the pioneer winding wire manufacturing industry of Nepal.
The unit produces Super Enameled Copper Winding Wires from SWG 8 to SWG 42, Bare Copper Strips, Paper Covered Strips, Earthing Wires, and Annealed Copper Wires to satisfy domestic demand while actively expanding exports to India and third countries. In addition, our expansion encompasses Cotton Covered Wires, Submersible Wires, and Rectangular Winding Conductors.

"You rely on us, we rely on experience — our slogan embodies our relentless pursuit of technological upgradation, uncompromising product integrity, and ethical conduct. Established in 1984 as Nepal’s first winding wire industry, our vision has always been to substitute imports with world-class domestic manufacturing and export high-performance electrical conductors across South Asia."
Through modern European wire drawing machines, continuous in-process laboratory monitoring, and rigid quality inspection, AWW guarantees wires that protect and optimize motors, pumps, transformers, and industrial equipment nationwide.
Every wire batch is tested against international IEC, IS, and Nepal Standard (NS) specifications across our 12 specialized laboratory testing machines.
Evaluates enamel flexibility and film adhesion without cracking or peeling under severe mechanical bending.
Measures thermoplastic flow temperature under high mechanical pressure and extreme thermal load.
Ensures enamel insulation maintains dielectric integrity when exposed to abrupt thermal spikes.
Heavy-duty testing to measure ultimate breaking load and tensile elasticity of drawn copper conductors.
