Ultra-high Voltage Grid is regarded as Electric High Way which features big capacity, distance and low loss. Until now, there are 750KV, 1000KV, 660KV, 800KV direct current in our nation's ultra-high voltage grids. Considering its safety, it has extremely higher requirement on insulating oil in transformer, mutual inductor and reactor, the ZYD-U Series Ultra-High Voltage Oil Treatment Equipment, manufactured by our company is effectively engaged in particles filtering, vacuum degassing, oil-water separation and break down voltage value increasing.

This oil treatment equipment has been successfully applied in 750KV alternating current and 800KV key projects. And all the oil treatment index reaches the national ultra-high voltage oil purification standard.

Features:

1. Powerful Vacuum design, High vacuum: Ultimate vacuum ≤2 pa, Working vacuum ≤ 30 pa.
2. Can be operated both on-load and off-load.
3. With UK G technology, this machine can dissolve and remove the water, trace water effectively and completely.
4. Multi stage filtration to remove the particles and impurities in different size
5. The treated transformer oil by this oil purifier, its oil breakdown voltage ≥75 KV; and moisture content ≤ 3 ppm; air content ≤ 0.3 %; and the filtering accuracy can be down to 0.5 μm.
   
6. Ideal for insulating oil clean up and transfer
7. Double-infrared fluid level controller control the oil level in the oil treatment machines automatically, keeping oil quantity balance
8. A trinity of interlocked preventive device among heater, oil pump, vacuum pump and electrical parts
9. Carbon fiber infrared heating system
10. Explosion-proof type available
11. Suitable for vacuum oil filtration, dedydration, degasification, oil filling, vacuum drying on line.
