The oil drain valve is a core supporting valve for transformers, mainly used for draining transformer oil and overhaul maintenance, and is widely suitable for oil-immersed transformers.
It drains the insulating oil inside the transformer body for equipment maintenance, oil replacement and oil sample testing.
It cooperates with oil injection to realize the cyclic replacement of transformer oil.
Some are integrated with a sampling function, allowing direct extraction of oil samples to test insulation performance.
Seals: nitrile rubber and fluororubber, which are compatible with transformer oil, oil-resistant and aging-resistant.
The pressure bearing capacity matches the internal working pressure of the transformer.
