Product Introduction
The FRP square tube is made from glass fiber untwisted yarn impregnated with epoxy resin, wound on specialized equipment,

and shaped using a mold system. This process results in a profile with high mechanical strength and a smooth surface.

Product Features
- Smooth surface and attractive color
- Low moisture absorption and corrosion resistance
- High mechanical strength and excellent electrical performance
- Suitable for high-strength insulation systems and compatible with transformer oil
- Good dimensional stability, heat resistance, and low specific gravity
- Long storage period and simple molding process
- Long-term heat resistance grade: Class B (≥130°C)

Product Applications
The FRP square tube is ideal for:
- Inner frames of low-voltage windings in amorphous alloy oil-immersed distribution transformers
- Electrical insulation ladders
- Model aircraft frames
- Wind turbine blades
- Cable trays
- Dry-type transformer insulation core rods
- Textile machinery
