Product Description

UL Certificated Professional Stranded Triple Insulated Wire Copper Winding Wire TIW for Transformers

UL Certificated Professional Stranded Triple Insulated Wire Copper Winding Wire TIW for transformers

Structure and Advantages of TIW Wire

Three-layer insulation structure: Typically from the inside out:

First layer: Base coating (e.g., polyurethane)
Second layer: Polymer film (e.g., polyester or polyamide)
Third layer: High-strength outer layer (e.g., nylon or special resin)

Advantages:

High dielectric strength: Can withstand thousands of volts without breakdown
No additional insulation required: Simplifies production processes and reduces labor and material costs
Good heat resistance: Typically withstands temperatures from 105°C to 130°C or even higher
High mechanical strength: Scratch-resistant and resistant to winding stress, reducing the risk of breakage during production
