Features of Products

As one kind of distributing transformer for mining use, KS9 series transformer has many advantages, such as compacted body, reasonable structure, low in spoilage, good in heat-dispersion and  easy to go into a well.
      This series of product adopt high-permeance cold-rolled grain-oriented silicon-steel plate of high-quality. The iron core applies echelon form iterative accumulation. The core pole which is multilevel circular cross-section can ensure of low noise and low spoilage.The structure of gasoline tank is very firm  Both side of tank are welded with cable junction boxes of high and low voltage which are used for wiring. High-voltage loops need tapping voltage that is  l:5% of rated voltage  It is using the tap switch to change the voltage When the voltage exchanges, the power must be cut off fist, then unveil the wind-rain cover on the tap switch to counterchange the voltage  The low voltage side of the transformer can be connect the type 'Y' of 693V or the type "D" of 400V to supply power And inside the cable junction box has a secondary terminal which educes six insulators for users' option  The joint hinges that welded on the casing are available and drawing crow-plate is mounted beneath the base. there are mounting holes in the drawing crow-plate used for being addly-installed with mine-car' contact roller when mine needing

Practicable Confines

The oil-immersed distributing transformer is applied to the capacity 630KVA or below, and the voltage 10KV or below. This product is normal one which has no requirement of explosion   proof  The main function of the product is for mine illumination when distributing power for mining as well as for the driving power.This series of transformers will not need lift-machine examination after transportation  It is allowed to assemble the unshipped spare parts for checking and acceptance.
