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.
