By choosing Composite Insulator Technology, excellent performance and reliability can be assured for the lifetime of your equipment:
- One piece tailored glass fiber composite tube - best mechanical and dielectrically performance
- High temperature vulcanized (HTV) silicone rubber with high amount of aluminum rehydrate (ATH) filler - improved tracking and erosion performance and best long term performance
- Seamless helical extrusion process for a continuous outer silicone housing - no mold lines where dirt or salt can accumulate
- Optimized shed profiles with large shed tip radius and high protective creep age distance - lowest possible leakage currents and electrical field
- High-strength aluminum end fittings - strong, gas-tight and leak-proof joint
Examples of applications in which our Composite Insulators are used:- High voltage circuit breakers (live tank and dead tank)
- Outdoor instrument transformers (current and voltage)
- Surge arresters
- Cable terminations
- Transformer bushings
- Wall bushings
- Gas insulated switchgear (GIS)
- UHVDC / UHV station post insulators
- Voltage dividers
Silicone rubber is the fastest-growing, most dominant polymeric insulation material for high voltage products. SINGREE Composite Insulators with silicone rubber offer significant benefits compared to the former porcelain technology:- Explosion-proof for maximum safety
- Non-brittle material with reduced risk of handling damages
- Leakage current control due to hydrophobicity
- Excellent insulation for reduced creep age requirements
- Flashover resistance
- Outstanding seismic performance provides safety and reliability
- Low weight for cost savings
- Maintenance-free and outstanding pollution performance
- UV stability
