Product details and performance characteristics

security

1) The product adopts Nomex Paper insulation system, with high flame retardant, explosion-proof and fire-proof rating.

2) Professional technology, high mechanical strength, strong ability to withstand short circuit, safe and reliable operation.

reliable

1) Class H (heat-resistant) temperature: 180 ℃. The main insulating material is class C (heat-resistant temperature: 220 ℃), with strong overload capacity.

2) Small partial discharge, high insulation level and long service life of the product.

3) The "Three Prevention" ability is excellent and there is no cracking.

environment protection

1) The products will not pollute the environment during transportation, storage and operation

2) The no-load loss is 70% - 80% lower than that of ordinary dry transformer, with remarkable energy-saving effect and short investment payback period.

3) The product is low noise and maintenance free.

4) The product can be recycled at the end of its service life to realize resource reuse.

Characteristics of iron core

1) The iron core raw materials are all made of Hitachi metallic amorphous materials, and the iron loss is 70% - 80% lower than that of conventional products.

2) The core structure is simple, and the unique technology makes its mechanical strength high, and its characteristics and structure will not be affected by transportation and vibration.

3) The unique three column structure of amorphous has the ability to resist high-order harmonics. Dynll and Yyn0 wiring can be used.

Characteristics of low voltage coil

The low-voltage coil is wound on the high-strength polyesterimide cylinder with imported high-quality copper foil and H-class insulating material. The insulating material Nomex Paper is used between the layers. The coil is impregnated into a solid whole by VPI vacuum pressure, and the upper and lower ends of the coil are sealed with resin.

1) The coil has high mechanical strength and strong short-circuit resistance.

2) The coil has strong thermal shock resistance and greatly improves the service life of the product.

3) The coil has strong ability of "moisture-proof, dust-proof and salt fog prevention".

Characteristics of high voltage coil

The high-voltage coil adopts multi-layer segmented cylindrical structure and longitudinal multi airway structure. The flat copper wire wrapped in Nomex Paper is used as the conductor. The insulating material Nomex Paper is used between the layers. The coil is soaked into a solid whole by VPI vacuum pressure, and the upper and lower ends of the coil are sealed with resin.

1) The multi-stage and layer winding design of the coil makes the initial point distribution of lightning wave between the turns of the high-voltage coil almost linear, so as to improve the ability of the coil to withstand sudden wave.

2) The coil has high mechanical strength and strong short-circuit resistance.

3) High heat-resistant insulation material and longitudinal multi airway design make the coil have strong thermal shock resistance and greatly improve the service life of the product.

4) The coil has strong ability of "moisture-proof, dust-proof and salt fog prevention".
