Energy Saving Copper Winding 10 2500kva Power Distribution Transformer - China

price: 850.00 Dollar US$

As the most widely used power facility, power transformers have a wide variety of types and are of great significance to energy conservation and emission reduction.

The S13 fully-sealed oil-immersed power transformer is currently the main selection product for power distribution equipment, with significant energy-saving effects.

At present, mainstream distribution transformers generally use S13 laminated core power transformers.

It adopts a fully oil-filled sealed type, no oil conservator, and a corrugated sheet box structure.

The volume of the transformer changes due to changes in temperature and load, which is completely adjusted by the corrugated oil tank.

Its no-load loss is much lower than that of S9, and it is resistant to lightning impact It has strong short-circuit resistance, obvious energy-saving effect, and reduces the overall size of the transformer.

The S13 transformer is made of high-permeability oriented silicon steel sheet with a thickness of 0.27-0.30mm and a unit iron loss of 1w/kg, while the new S9 type is an ordinary silicon steel sheet with a thickness of 0.30-0.35mm and a unit iron loss of 1.20 -1.55w/kg.

The S13 distribution transformers produced by our company all use 30P series high-permeability oriented silicon steel, using foil-wound coils and new insulating materials and processes.

The product is resistant to high temperature, impact, and fully sealed structure design to ensure the stability of transformer oil quality It prolongs the maintenance cycle.

At the same time, the integral fuel tank composed of corrugated fin radiator is produced by phosphating and multi-layer anti-rust spraying process, which has good weather resistance.
