22kV - 2000kVA Cast Resin Dry Type Transformer, Three Phases, Two Winding, Power Distribution
Dry transformer Feature:
Pearl Electric adopts advanced technology and high quality raw material, with first class equipment and strict processing, PEC-S- cast resin dry type transformer owns the following advantages:
1. Copper conductor is used both for H. V. &L. V. Coils to strengthen the glass fiber. It is dried and cast by epoxy resin under the high vacuum. After curing, it is a firm cylinder, with high mechanical strength and withstanding short-circuit capability, smaller partial discharge, higher reliability as well as long service life.
2. Flameproof, explosion resistant, no pollution to environment. Because the imported epoxy resin and glass fiber compound insulation materials are used and certain silicon powder is contained in the epoxy resin. Heat conduction co-efficient and flameproof ability is greatly improved in comparison with old type materials. There would be no toxin and harmful gas caused by resin under high temperature.
3. The moist cannot be absorbed by coils. The core clamp is coated with the special anti-corrosive materials so it can do as usual under the severe conditions. It is unnecessary to get rid of moisture for interval operation.
1 After the transformer is installed, the system earthing reliability should be strictly tested and checked, thus to ensure reliable earthing of the system.
2 To avoid occurrence of accidents, a fence should be erected around the transformer without protective enclosure before putting into service.
3 DO NOT touch the transformer’s main body with power switched on.
4 Only qualified technicians can perform testing, installation and maintenance work.
