Transformer, Tap Changers

Tap Changers come in many styles. All require good insulation to work properly for many years. Norplex-Micarta has a specific line of materials designed for this application that improve the track resistance when compared with alternate material construciton.

HP563

Know for its arc/track resistance, HP563 also has excellent flame resistance and low smoke generation.

NP509

NP509 (NEMA G-9) consists of woven glass fabric combined with a melamine resin system.

NP613

NP613 is constructed from electrical grade of kraft paper and a specially modified thermoset epoxy resin system.

NP615

NP615 combines a NP612 core with high resin content melamine impregnated surfaces for improved arc resistance.

NP643

NP643 is a thermoset material constructed from electrical grade kraft paper and a specially modified high temperature epoxy resin system.

RT628

It is an improved machining grade meeting NEMA XX and MIL-I-24768/11, Type PBG for tubes.
