Electrical Insulation Enamel

Electrical insulation enamel is used on copper and aluminum wires that are used in motors, transformers, generators and electrical measuring instruments. By applying heat on the wires, they are strengthened and have the property of electrical insulation coating. Coated wires are called “magnet wire”.

Wires insulated by electrical insulation enamel

Electrical insulation enamel is applied to copper and aluminum wires up to 30 layers, which creates a suitable electrical insulation layer.

This product must have very good chemical and thermal resistance and adhere well to copper or aluminum wire and have excellent mechanical stability. In some cases, for example when used in inverter electric motors, the appropriate insulation layer must withstand a possible partial discharge, which can cause a short circuit and damage the motor.

Thanks to Amitis Tejarat Noor’s close relationship with the international wire magnet industry, the company is able to continuously monitor new technologies and production processes and adapt its products portfolio to meet the changing needs of the market. .

Chemically, the range of electrical insulation enamel includes polyurethane, polyester, polyester amide, polyamide imide. The range of solids content starts from close to 8% and ends at 60% (1g/1h/180°C) and the viscosity range is between 30 and 60,000 mPas (at 23°C).
