Product Description

6520&6521 Insulation Paper/Presspaper/Fish paper
 

Product Description

This 6520/6521 insulation paper is a two-ply flexible laminated insulation material consisting of press paper and polyester film. The used adhesive is acid-free and temperature resistant. It has excellent electrical and mechanical properties, can be used for low-voltage motors, insulation, and cushioning interterm insulation. It can be used as slot and phase insulation in low voltage machines or as interlayer insulation in transformers.
