Completely Sealed Distribution Transformer
Completely Sealed Distribution Transformer contains
oil tank, which is completely isolated from air. The elasticity feature
of the oil tank compensates the volume transformation of oil tank, the
moisture and oxygen cannot enter the tank. This can slow down the aging
of insulating materials. This improves operation reliability of the
product.
Features
1. The oil inside transformer isolates from air and ensure the
transformer can be used continuously for 20 years without any
special process. There are no oil storage tank and protection devices.
2. The transformer applies vacuum oiling in the vacuum oil filling plant equipped at JAYBEE to achieve sealed effect.
Application
City Electric Network, Petrifaction, Metallurgy and other occasions with heavy humidity and in convenient maintenance.
