Product Introduction

This product implements national standards GB 1094- 1996 the power transformer "and GB/T6451-2008 the three-phase oil-immersed power transformer technical parameters and requirements".

S11 series transformer is the latest series of low loss copper windings products, the products using high-quality materials, in coil implement body and insulation, using new craft, new material, thus made racing, load loss reduced significantly, and performance and structure more reliable and superior.

Product Features

*Good economic performance
On the basis of S9 series, the no-load loss of S11-S13 series products is reduced by 30% on average, and the no-load current is reduced by 70%-85% compared with S9 series..
*Long service life
Transformer tank adopts fully sealed structure, which can be bolted or welded along the tank. Transformer oil does not contact with air and prolongs service life.
*Running high reliability
Improving the concerned tank sealing parts, increasing reliability improvements to ensure and improve technology level of reliability of sealing.
*Floor area is small
S11-M, S13-M series transformer tank adopts wave plate radiator, when the oil temperature change, the corrugated plate heat bilges cold shrink can replace storage cabinet role, corrugated plate appearance tank looks nice and covers small area .
