>>> Product Summarize
Our
company production of 220kV oil immersed power transformer R&D based on
digested and absorption of advanced technology both at home and aboard, and the
characteristics of urban and rural power grid. Its superior product performance
index is better than GB/T 6451-2008 “oil immersed transformer, electric power,
technical parameters and requirements” completely accord with JB/T 3837-2010”
transformer products model establishment method” and GB 1094.1.2-1996, GB
1094.3-2003, GB 1094.5-2008 “power transformer” manufacturing standard and the
international electro technical commission recommendation IEC 60076.
>>> Function and features
This
series of products with the characteristic of low loss, low noise, no need to
hang the core, safety, reliability, economy can be guaranteed. The transformer
core USES multilevel ladder up fold, laminated to 45° inclined seam no hole binding structure, the
burr of silicon steel shear mouth less than 0.02mm. The core of advanced over
table, strict pile up fully guarantee the grain orientation of cold rolled
silicon-steel sheet, effectively reduce no-load loss of the transformer. Coil
quality non-oxygenic copper wire windings, all are auxiliary support inside,
lateral braces are locked in the changing, adopting unique hill-climbing pad,
greatly enhances the winding resistance of the mechanical strength and short-circuit
capacity. The new body transformer technique, make a unit of strong body and
tank. Tank structure form for bending corrugated bell cover, beautiful
generous. All are processed with groove sealing seal structure. Box along with
double oil way sea. Ensure transformer tank no il leakage, Transformer can
withstand transportation level acceleration 30 square meters/s collision,
transformer in transit outfit 3d collision recorder.
