Performances
High Insulation: Non-conductive, no magnetic hysteresis, no eddy current losses — ensures electrical safety of transformers.
High Strength: Specific strength superior to metals, meeting the load-bearing requirements of insulation structures.
Lightweight: Density only 1/4 that of steel, reducing overall equipment weight.
Heat Resistance: High heat deflection temperature, suitable for long-term temperature rise conditions in transformers.
Adjustable Coefficient of Thermal Expansion (CTE): Can be tailored via material design to match metal thermal expansion, reducing thermal stress.
Corrosion Resistance: Resistant to oil, moisture, and salt spray — suitable for both oil-immersed and dry-type transformers.

Applications
Internal Transformer Fastening
Core clamping, winding fixing, insulation assembly — eliminates eddy current losses, ensures insulation distance. Suitable for distribution, power, and high-voltage large-capacity transformers.
External Transformer Fastening
Housing accessories, HV bushing fixing — isolates live parts, resistant to outdoor and coastal corrosion. Suitable for 35kV and above transformers.
Specialty Transformers
Dry-type, corrosion/explosion-proof, UHV (1000kV) — meets requirements for oil-free insulation, acid/alkali resistance, flame retardancy, and extreme conditions.
Other Power Equipment
Reactors, HV switchgear, frequency converters, converter valves — reliably fastens coils, cores, and insulation components.
