Home > Products> S11-M Series Sealed Transformer  
Scope of Application:
Product makes use of any power supply location as well as European Box-transformer, mobile transformer substation and so on.
Features of production:
Superior performance gets to the international level. It can save energy in evidence. Comparing to GB6451-1999, its no-load loss drops by 30% in average, the load loss drops by 22.4% in average. It has strongpoint of no suspended-core, no-maintenance, easy to set and low general cost and so on. Firm configuration and good at anti-short circuit performance. The corrugated iron is made of imported steel plate and made with imported equipment, good-looking, workable, durable. Tank and clamps go through acid picking and phosphorization, painting for times after rust frss processing, to make the paint film keep on.
