Insulator Coating

At Preventive Power and Maintenance, we lead the industry in insulator coating by combining expertise, innovation, and safety. What sets us apart is our ability to apply high-voltage insulator coatings while equipment remains energized, using specially designed, thoroughly tested insulated wands. This allows us to eliminate costly outages and downtime while still delivering a reliable, high-performance coating.

Coating insulators is not just a maintenance task—it’s a critical step in protecting electrical infrastructure. Over time, insulators are exposed to contaminants like pollution, salt, and dust, which can cause surface leakage and tracking, leading to flashovers and failures. Our protective coating forms a durable hydrophobic barrier that repels moisture and contaminants, dramatically improving system reliability and preventing outages.

By trusting Preventive Power and Maintenance, you’re ensuring your system stays online, protected, and efficient—without compromising safety or performance.

Our insulator coating service is designed to reduce flash overs to zero. Engineered to last up to 10 years, our coating process enhances reliability, reducing maintenance cost, and ensures your electrical infrastructure stays protected and energized.
