Enamel wire, also known as magnet wire, is a copper or aluminum wire coated with a thin layer of insulating enamel.
Features of Enamel Wire
Thin Insulation Layer
Extremely thin enamel coating allows high-density winding without increasing coil size.
Excellent Electrical Insulation
Prevents short circuits between turns while maintaining compact wire diameter.
High Thermal Resistance
Available in multiple temperature classes, ensuring safe operation under heat stress.
Mechanical Durability
Resistant to bending, vibration, and winding stress, reducing risk of damage during assembly.
Types of Enamel Wire
Polyurethane (PU) Enamel Wire
Thin, flexible enamel coating with good mechanical and thermal properties.
Polyester (PET) Enamel Wire
Offers higher thermal resistance (up to 155°C) and good abrasion resistance.
Polyimide (PI) Enamel Wire
Excellent heat resistance (up to 200–240°C) and chemical stability.
Double-Coated Enamel Wire
Two layers of enamel provide enhanced insulation and mechanical protection.
Triple-Coated Enamel Wire
Three enamel layers for maximum insulation and durability.
High-Temperature Enamel Wire
Special enamel designed to withstand temperatures above 220°C.
