The Challenge Inside Power Plants
Coal-fired and thermal power stations are harsh environments for electrical equipment. Insulators and bushings are constantly exposed to dust, fly ash, coal soot, steam, and chemical contaminants. These pollutants settle on surfaces, creating conductive paths. Add moisture or condensation, and you have the perfect conditions for tracking, dry-band arcing, and flashover—leading to outages, costly repairs, and safety risks.
Why Silicone Coating Is the Solution
SI-COAT 570 HVIC is engineered to protect high-voltage components in the toughest conditions. Unlike traditional cleaning cycles or grease applications, silicone coatings provide long-term hydrophobic protection and resist contamination.
Key Technical Advantages:
- Hydrophobic Surface: Prevents water films and leakage currents.
- Arc & Tracking Resistance: Stops flashover even under severe pollution.
- Dust & Coal Soot Protection: Repels particles that accumulate on insulators.
- UV & Weather Resistance: Ideal for outdoor substations and exposed equipment.
- Easy Application: Brush or spray on porcelain, glass, or composite insulators.
Where to Apply in Power Plants
- Transformer Bushings: Protect against contamination and moisture ingress.
- Switchgear & Busbars: Reduce risk of tracking in high-pollution zones.
- Outdoor Substations: Combat salt spray, fly ash, and industrial pollutants.
Lifecycle Benefits
- Reduced Cleaning Cycles: Silicone coatings maintain hydrophobicity for years.
- Lower Outage Risk: Prevents failures caused by contamination-induced flashover.
- Extended Asset Life: Protects insulators and bushings from environmental stress.
