Copper and Aluminium Round & Rectangular Conductors

Over the last 28 years Comax has been deeply involved in the manufacture and rewinding of rotating Electrical machines. That depth of experience gained over those years has led the management of Comax to align the company with the most reliable manufacturers of aluminium and copper rectangular conductors.

We have available materials for all applications of rotating and static machines, generators, alternators, transformers and motors. We can supply almost any insulation from enamel to mica, paper to glass, Normex to cotton and any combinations of any materials.

Our products are exported to every continent where a fast reliable supply of quality product is demanded. Our main markets are Europe, Middle East, Africa and South America.

Our quality, reliability and efforts to give satisfaction have placed us in a unique position within the winding industry. Our suppliers have ISO 9001 and UL approval for many products.
