China Suppliers High Voltage Three Phase 1600KVA 30KV 0.4KV Oil-immersed Fully Sealed Construction Transformer Toroidal Coil Structure Transformer

Product Introduction

The S11,S13, S20-30~2500 series three-phase hermetically sealed oi-immersed power transformer has the advantage of low loss, low noise and high efficiency, which can obtain good energy-saving effect and reduce pollution. Compared with ordinary oil-immersed transformer, hermetically sealed transformers don’t need oil conservator, oil volume is automatically regulated and compensated by elastic corrugated sheet of corrugated tank. Transformer oil is kept out of air, which can effectively prevent deterioration and insulation aging of oil and enhance operation reliability.

Product Feature

1. Transformer core is laminated by high permeability and low loss cold rolled silicon steel, joint gap is small, and each layer’s joints are staggered, which reduced no-load loss, no-load current and with less noise.

2. Compact structure of transformer reduced the radial force in short-circuit condition and withstand high sudden short-circuit current.

3. The transformer is hermetically sealed structure, maintenance free, and long service life.
