Amorphous alloy oil immersed transformer

Features
1. The core is would with amorphous alloy ribbons, which possesses a no-load loss as low as about 75% to 80% that of a S9 type transformer(with silicon steel core).
2. The notable feature of the amorphous alloys transformer is little no-load.
3. Amorphous alloys transformers are the ideal equipment supplying power for distribution network in country, villages and towns and townsman.
4. Amorphous alloys transformers are the ideal equipment supplying power in industrial and mining enterprises which use their load in the 50% to 80% range.
5. Amorphous alloys transformers ensure equipments can be reliably circulated, it are beneficial to energy and function saving.
6. Amorphous alloys transformers is no-load low loss, fever less, low temperature rise, stable performance.
7. The LV coils are would with foil, anti-strong short-circuit, the strong ability to withstand short-circuit.
8. Amorphous alloys transformer with Dyn11 connection can lighten harmonics impact on the network and improve the quality of the power supplied.
9. Amorphous alloys transformer with strong overloading ability, reliable safe operation, the capacity with corrosion-resistanct and repair-free.10. The amorphous alloy transformer adopts the full-seal structure, the insulating oil and insulation medium is free of air pollution, it is available to be operated in the damp environment.
11. The amorphous alloy oil-immersed transformer can reduce the harmful gas like CO, SO2, NO2, etc., it is called the "green environmental-protection product" of the 21st century.

Oil immersed electric transformer

Applications
S11-(M)type 10kV class fuly sealed power ranstormer is a new type product developed and manufactured by our company according to nationalstandard. The product features compact structure, atractive appearance,small size low temperature rise noise and strong overload capacity.Compared with S9 series product, the no-load loss reduces more than 30% and no load current reduces 45%-80%. It is one of the most energy saving products in China.

Fully Sealed Distribution Transformers

Applications
S22, S20, S13 series products are in line wth the national standard GB1094 Power Transformer and GB/T645 Technical Parameter
and Requirement of Three-phase Oil Immersed Distribution Transformer.
S22, S20, S13 series ful-seal distribution transformer is an energy-saving product that has the broad application prospect, the no-
load loss is 20% lower than that of S11 type transformer.

Features

The iron core adopts the high-class coldrolled oriented slicon steel, 45 three-class sloping seam, no punching. and the limb is coated withthe polyurethane varnish and solidified.The coil adopts OFC conductor, with reasonable structure, improving the abilty to resist the sudden short circuit.It is provided with effective support at winding and surface, to further improve the short circuit resistance of windingIt cancels the ol tank, the wings of ripple olltank take the place of oil tube as the cooling element, and can expand and contract with the oilvolume of transformer, the transformer ollis isolated with the air, to prevent and aleviate the oil deterioration and insulation dampness, improvethe operation reliability, in addition, it is free maintenance under normal operation.
