　　XDL series oil level gauge is a dedicate product for full sealed transformers. The product takes the screw-threaded connection instead of the old flange connection. It is reliable, simple, safe and convenient. The screw-thread connection not only shortens the working time, but also improves the working efficiency.

　　The multifunctional XDL series oil level gauge produced by our company is installed on the top of the transformer tank. There are two colors in the buoy indicating device to show the inner oil level of the transformer: green and red. The green means that the oil level is normal. The red means that the oil level falls and we should refuel the transformer. The XDL series oil level gauge is of multiples functions. It can be used as oiling connection pipe and can be used in pressure relief valve installation and pressure measurement of vacuum pumping connection transformer. The screw-threaded connection can guarantee the rational compression amount of the seal ring, and meanwhile, it can prevent the ultraviolet ray effectively to prolong the life of the seal ring. We can observe the oil level through the observation window in 360 degrees, so we can see the accurate oil level changes in any angles.

　　The product uses the seamless steel pipes with high quality which is safe, reliable and artistic. Its appearance is coated with anti-static plastic which conforms to the three proofings requirements.
