Product Description

Product Description

1. DESCRIPTION

6520/6521 Polyester film/Presspaper flexible Laminate is a two-layer flexible composite material.
According to different thicknesses of Polyester film, 6520/6521 can be divided into 6520-23 / 6520-36 / 6520-50.


2. FEATURES

• Thermal class B (120°C)
• Excellent dielectric properties and mechanical strength

 

3. APPLICATIONS

• As slot, interturn and liner insulation for E-grade motors, generators and electric appliances.
• Also used for slot insulation, closures or covers, overhang, interphase insulation and layer insulations for Dry-type transoformers and motors.
