General:
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 lockout.Even after long-distance transportation,they are
not loose.All sealing material is made of high quality acrylic rubber,which can effectively prevent against light-
aging,electricity aging and heat aging.It is equipped with "remote sensor" signal thermometer and pressure
relief valves to enhance the reliability of transformers.
Main Features:
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 lighting.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 adopted in the sealing parts
Vacuum oil filling process is used.
