The core advantages of the solution

1. High insulation safety: The breakdown voltage of the insulating paint far exceeds the industry standard, eliminating the risk of insulation breakdown at high voltage; The residual amount of the product is ≤ 0.05% to avoid the hidden danger of partial discharge;

2. Super weather resistance and corrosion resistance: temperature resistance coverage - 50°C~200°C, anti-corrosion scheme salt spray resistance for more than 1500 hours, suitable for extreme environments such as high altitude, extreme cold, and high temperature;

3. Strong connection reliability: structural adhesive resists vibration and shock, low resistance and stability of solder joints, reducing the risk of equipment failure;

4. Compliance Adaptation: Comply with UHV industry standards such as IEC 62271 and GB/T 1094, and environmentally friendly formulas have passed SGS testing.

The application value of the scheme

1. The life of UHV core equipment is extended to 20 years+, the operation and maintenance cycle is extended by 30%, and the whole life cycle cost is reduced by 30%;

2. The equipment failure downtime rate is reduced to less than 0.1%, which meets the core demand of UHV "long cycle and less maintenance".

3. Help the project pass the environmental protection acceptance and avoid policy compliance risks.
