Description
Product Introduction
Our high-voltage fully enclosed transformers are engineered for reliability in critical power distribution systems. Featuring hermetically sealed corrugated oil tanks, they eliminate oil contamination and minimize maintenance. Integrated with high-pressure adhesive sealants , these transformers ensure leak-proof joints in bushings, radiators, and casings. The sealants offer exceptional thermal resistance and dielectric strength, enhancing safety and longevity. Ideal for urban grids and industrial applications, they combine efficiency with robust construction for sustained performance.
Functions
-
Fully enclosed transformers utilize hermetically sealed structures (e.g., corrugated oil tanks) to isolate internal components from external contaminants such as moisture, dust, and corrosive gases. High-pressure sealant adhesives, such as silicone-based compounds, reinforce these seals at joints, bushings, and access ports, ensuring long-term oil purity and preventing leakage. This design extends the transformer’s lifespan by minimizing insulation degradation and reducing maintenance frequency.
-
The corrugated tank design accommodates thermal fluctuations caused by load variations. High-pressure sealants maintain flexibility across extreme temperatures (-60°C to +155°C), allowing the transformer to expand and contract without compromising the seal. This adaptability prevents structural stress and ensures consistent performance in fluctuating climates.
-
Specialized sealants with high dielectric strength (e.g., silicone rubber formulations) reinforce electrical insulation at critical interfaces, such as bushing connections and cable terminations. By mitigating partial discharge and arcing risks, these adhesives improve operational safety and reliability, especially in high-voltage applications (e.g., 11 kV to 33 kV systems).
-
High-pressure sealants enable quick-curing bonding of transformer components, reducing downtime during assembly or field repairs. Their room-temperature curing properties eliminate the need for heat treatment, streamlining installation processes. This efficiency is critical for urgent maintenance in industrial or utility settings.
-
The combination of fully enclosed designs and robust sealants ensures compliance with safety standards (e.g., IP65 protection against dust/water ingress). By preventing oil leaks and electrical faults, these transformers reduce environmental risks and enhance operator safety, making them suitable for urban grids, renewable energy installations, and hazardous industrial environments.
