1)had passed ISO9001:2000 and CE certificate; 2)distribution transformer; 3)eliminating oil counters; 4)operation reliability

    S9 series sealed-type distribution transformers as compared with ordinary oilimmersed transformers,eliminating oil counters,from wing to replace the  waveripple tank tubing for cooling heat-dissipating components,corrugated tank by high-quality cold-rolled steel sheet manufactured in a dedicated production line,wave fin can be changed with the volume of the oil press device sizing,so taht transformers and isolated from the atmosphere toprevent and mitigate oil deterioration and insulation damp,enhance operation reliability,the normal operation and maintenance.

Corrugated surface through to the oil tank to rust,phosphate after treatment with three anti(rain,moisture-proof,anti-somke)pain coating,suitable for metallurgical, peterochemical and other productions enviroments.
