Description
Description
Introduce

The body of porcelain boxes were installed in the welded by steel ,and has four mounting holes on the circular base.

The upper part of the porcelain box equipped with a storage cabinet ,porcelain boxes,storge cabinet  and built then and by mechanical means between the base joint are sealed with good elasticity ,anti-oil rubber pad in the oil storage cabinet equipped with a fuel gauge .

Marked with red paint next to the fuel gauge,oil height of the surrounding air temperature , covered in the storge cabinet equipped with a safety that can be automatically opened when the transformer internal pressure is too large airway. Equipped with a coil in the wall of  the storge cabinet succeed .

Mark P1 represents a begining of the coils, The P2 on behalf the end of the head ,P1 succeed porlain sets and stoge cabinet insulation.P2 succeed and storge cabinet for direct  electrical connection.

Features
This type of transformer insulation from epoxy resin core with high-quailty magnetic materials.Primary and secondary windings and core are cast in epoxy resin.
With excellent insulation properties and moisture resistance,and easy to do surface cleaning.
Qualifying time at the top of casting body,the outlet side marked as P1,P2,a secondary winding(measurment level)outlet side of 1S1,1S2,the second secondary winding(P) outlet side 2S1,2S2,mutual inductance is less class levels.
The base has four mounting holes for installation.
