EMR Tap Changers Private Limited

FRP Cylinders are a key dielectric material used in the transformer industry.

Widely adopted in structural, chemical, and commercial applications due to excellent mechanical properties.

Easun MR manufactures FRP cylinders that meet strict transformer industry quality standards.

Filament winding technology is used for production.

CNC-controlled winding machines wind resin-impregnated glass fibres onto mandrels.

Epoxy resin curing is done in temperature-controlled furnaces.

Mandrels rotate during curing to prevent resin displacement.

After curing, the material is cooled and the mandrel is removed from the cylinder.

Winding angles (5°–88°) are adjusted based on application needs:

• Low angles (BFW): High bending strength.

• High angles (PFW): High pressure resistance.

• Combined angles (PBFW): Withstand both bending and internal pressure.

Manufacturing complies with ISO 9001 standards for quality and safety.

Available in diameters from 28 mm to 1000 mm.

Made with E-glass fibre and high-temperature curing epoxy resin.

Raw materials sourced from renowned suppliers to meet high electrical and mechanical standards.

Used as housings, drive shafts, contact carriers, etc.

Requires high electrical and mechanical performance.

Designed for precision machining to meet OLTC demands.

Modern FRP cylinders are replacing hard-paper cylinders.
