MINING THREE-PHASE OIL -IMMERSED DISTRIBUTING TRANSFORMER

As one kind of distributing transformer for mining use. KS9 series transformer has many advantages, such as compacted body, reasonable structure, IOW in spoilage, good in heat-dispersion and, easy to go into a well.

This series of product adopt high-permanence 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 gaso 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 15% 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 counter change 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 i Unction 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 addle-installed with mine-car' roller when mine needing

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 pads for checking and acceptance.
