Electrical Machine phase / Slot insulation tapes

The insulation tapes on the basis of polyamide paper i.e.Nomex. Polyamide paper is an excellent insulator which offers good temperature resistance, dielectric strength, mechanical toughness and flexibility.  PPI self-adhesive tapes for electrical insulation encompass all insulation classes from Y to H in the working temperature range from -200°C to +400°C. Heat resistant adhesives are thermoplastic with good tack and limited resistance to solvents. Thermosetting adhesives cure when subjected to heat and provide excellent resistance to solvents, impregnating resins and cast resins. Heat-sealing adhesives, thermoplastic as well as duroplastic can be activated by solvents or by heat. They give strong adhesion under pressure.

PPI 6512
polyamide electrical tape with thermosetting polyacrylate adhesive/ heat class H

A polyamide paper i.e. Nomex® based insulating tape

Applications: 
electrical motor building
traction machine manufacturing
insulation for bar wound armature
insulation for bar wound armature
phase insulation, layer insulation
coil banding and wrapping
PPI 6610
polyamide/mica paper electrical tape with thermosetting synthetic rubber adhesive/ heat class F

based on Nomex® polyamide paper with mica. To facilitate ease of handling PPI 66100 is supplied with an easily removable interliner.
Polyamide paper resembles cellulose paper as regards flexibility. With the addition of mica the dielectric strength of PPI 66100 is improved relative to the standard PPI polyamide tapes.
PPI 66100 contains a synthetic rubber adhesive designed to give excellent adhesion to a wide variety of substrates. When PPI 66100 is subjected to the recommended curing cycle the adhesive bond strength increases to a value far higher than quoted here.

Applications: 
PPI 66100 has found widespread use in die-cutting operations, insulation requirements in high temperature machines, transformers, field or solenoid coils, traction machine manufacturing; phase insulation and generators; machine wide for wrapping bar wound armature.
PPI 6710
creped polyamide paper electrical tape with thermosetting polyacrylate adhesive/ heat class F

A creped polyamide paper i.e Nomex® based insulating tape

Applications: 
especially suited to phase insulation due to greater flexibility
