Insulating Silicone Filling Liquid for ZW7 Vacuum Circuit Breaker

Insulating silicone filling liquid is a high-flowability silicone-based material designed for ZW7 vacuum circuit breakers, 35kV switchgear, and other high-voltage electrical equipment. It is mainly used for insulation filling, moisture protection, sealing, and anti-condensation protection.

ZW7 vacuum circuit breakers are often used in outdoor power distribution systems. During long-term operation, moisture, dust, temperature changes, and condensation may affect the insulation performance of the equipment. Insulating silicone filling liquid can fill small gaps inside porcelain sleeves, current transformer areas, and other insulation structures, helping improve electrical safety and equipment reliability.

Key Features

• High dielectric strength

• Excellent insulation performance

• High flowability for easy filling

• Waterproof and moisture-proof

• Anti-condensation protection

• Good high and low temperature resistance

• Suitable for outdoor high-voltage equipment

Main Applications

This product is suitable for:

• ZW7 vacuum circuit breakers

• 35kV high-voltage switchgear

• Porcelain sleeve filling

• Current transformer insulation protection

• Outdoor electrical equipment sealing

• High-voltage equipment maintenance

Compared with ordinary silicone grease, this filling liquid has better flowability and is more suitable for insulation filling inside high-voltage equipment. It helps reduce moisture risk, improve sealing performance, and protect key insulation parts for long-term operation.
