Product Description
The hermetically sealed transformer is the transformer of which inner tank is totally isolated from the outside atmosphere, its volume changes with shrinkage and expansion of the corrugated tank sides. Moisture and oxygen can not enter the tank from outside, thus slowing down the aging of the insulating material. It doesn't need core-lifting check before operation or maintenance after putting into operation, which greatly improves the reliability of transformer. It adopts PCCAD as design software, and meets IEC60076, GB1094 standard, and has passed the ISO9001 quality system certification. The coils, wound by high intensity enameled wire(or paper wrapped)with cylinder(or disc) structure and ampere-turn balance, reasonable insulation structure, have a good short-circuit withstand capacity. The fastening parts are locknuts. Even after long-distance transportation, they are not loose. All sealing material is made of high quality acrylic rubber, which can effectively prevent againest light-aging, electricity aging and heat aging. It is equipped with "remote sensor" signal thermometer and pressure relif valves to enhance the reliablity of transformers.
It is suitable for 10kV, 50Hz power transmission and distribution, It can be used in residential areas, commercial streets, industrial and mining enterprises and rural areas for power supply and lightings
This product has the characteristics of energy-saving, long service life, high operation reliability and small occupation area.
Without such device like conservator and air breather, it ensures that the transformer oil is not in contact with air. So commonly, the transformers can be used for continuously for 20 years without any particular treatment.
Excellent rubber is adpoted in the sealing parts
Vacuum oil filling process is used.
