Product description:

My company is the production of dry type transformer voltage 6kV, 10kV and 35kV. Oil immersed transformer from the core and high and low voltage winding, company production of transformer by high-quality materials, quality process is chosen professional grade substation safety products, following prominent features:

First, iron core

High quality cold rolled grain oriented silicon steel sheet with mineral oxide insulation material for iron core. (there are also amorphous alloy core transformers using amorphous materials.

Through the selection of the material and grade of the iron core, the control of the cutting and stacking process makes the loss level and the no-load current drop to the lowest, and obtains the very low noise level. An iron core is assembled on the surface of a F or H grade resin to protect from corrosion and dust.

Two, low voltage winding

Low voltage winding to high-quality copper foil winding and, so in case of a short circuit realization of zero axial short-circuit stress; layer between the dispensing paper insulation. End winding with thermosetting epoxy prepreg cloth seal. Low voltage winding terminals for tinned copper, ensure the low-voltage connections without contact interface (such as conductive paste or double sheet metal). The assembly of the low-voltage outlet terminal is completed in accordance with the current mature technology, which comprises a spring pressure washer under the nut and the bolt head.

Three, high voltage coil casting process

The high voltage winding is made of copper wire wound, the coil is fixed, and the short circuit impact resistance is strong.

Four, performance characteristics

1) low loss, energy efficiency in line with the latest GB20052 first / two energy efficiency standards

2) low noise, better than GB and IEC standards

3) more severe environment / climate test test than C2-E2

(4) global unique, more secure, excellent fire performance (F1 test)

5) global operational verification of high reliability

(6) higher lightning strike resistance level (95kV 10kV)

The main users of the product is widely used in China Southern Power Grid, Inner Mongolia Electric Power Corporation, Shanxi electric power company, Liaoning province power company, Jilin province power company and user engineering and industrial users substation already achieved significant operational performance. Products currently operating in the power grid has more than 10000 units (surface).
