Description

Hermetically Sealed Oil-Immersed Distribution Transformer

This Hermetically Sealed Distribution Transformer is an advanced oil-immersed, non-breathing transformer engineered for long service life and minimal maintenance. It features a completely sealed tank system, eliminating the need for an external conservator. The design includes either corrugated tank walls or a flexible diaphragm, accommodating internal pressure variations due to temperature changes without atmospheric contact, thereby reducing moisture ingress and prolonging insulation life.

Available in multiple mounting configurations—including pole-mounted, pad-mounted, dead-front unit substation, and package substation types—this transformer offers installation flexibility across various distribution networks. With input voltage options ranging from 3.3 kV to 34.5 kV, and standard output of 400V/230V (customizable to match load requirements), it serves both rural and urban power distribution applications.

Constructed with Class A, B, or F insulation, depending on thermal and environmental needs, it supports stable performance under load while ensuring long-term reliability.
