To handle electrical stresses, transformer oils are required to have better dielectric strength. Lower residual water, gas and contamination content must be maintained to reduce the speed of oil ageing. All of these operations are performed using the ZYD Series transformer oil treatment equipment. Vacuum dehydration, degreasing and solid particle filtration are function of ZYD transformer insulating oil filtration equipment.

ZYD series double-stage vacuum transformer oil purifying machine is applied for heating, eliminating moisture, particulate matters and unnecessary gases of contaminated insulating oil used in transformers, mutual inductors, circuit breakers and switches. It is specially suitable for on-site installation, maintenance and purifying high level new oil, or running oil from big power transmission and distribution equipment and transformers on national main power transformation grid, which is above 110-750KV. It is an affordable centifuge oil machine in order to centrifugate dielectric oil for transformers.

The unit can carry out oil treatment, vacuum oil injection and cyclic hot oil drying in the installation and maintenance of transformers. It also can be mobile, 4 wheel mounted type and configured into double-stage high-vacuum oil filters to meet the greater needs for oil treatment.
With our special regeneration unit, it can change black color to original color and recover other oil properties.

 which is formed by heater, oil pump, oil-inlet ball valve, oil extraction ball valve, this system can heat, pipe and extract the oil which needs to be purified, and therefore to make the oil flow orderly during the purifier is running and finally to refine the oil completely. 

which is constituted by preceding stage sliding vane rotary vacuum pump, backward stage Roots blower pump, air-in valve, vacuum separation drum, liquid-vapor separator, and water storage tank. These units form an integrated vacuum return circuit, on one the hand to fulfill requirements of oil refining, on the other hand to constitute a air-bleeding set which can vacuumize oil containers.
