Product Description

Whether you need a distribution transformer for your factory, plant, or facility, our 630kva three-phase transformer is the ideal choice. Purchase now at a competitive price and experience the difference in power transmission efficiency!

Product Characteristics
Iron Core
Our transformers feature an iron core made from cold-rolled silicon copper sheets with high magnetic permeability. This new type of core employs a full oblique joint stacking method, with the core column exhibiting a multi-step circular section, and consistent sections for both the iron yoke and the core itself.

Winding
The winding process incorporates corrugated oil channels and a no-paint dipping technique, ensuring tight tape binding. The concentric coils of the winding include a high voltage winding with essential tap connections, leading to the tap-changer. The switch, mounted on the box cover, allows for voltage adjustments prior to tapping.

Safety Protection Device
Our transformers, ranging from 30 to 2000kVA, come equipped with pressure relief valves to ensure safety.
Additionally, gas relays with alarm and tripping terminals are available upon user request, enhancing the protective measures.
