Explosion Proof Dry Type Distribution Transformer For High - Rise Buildings

10/0.4kv Dry Type Transformer

Epoxy resin cast dry-type transformers, can be used as oil-immersed distribution transformer replacement

products, all types of dry-type transformers in the best performance products, especially for urban power

grids, high-rise buildings, business centers, theaters, hospitals, Hotels, tunnels, subways, underground

power plants, laboratories, stations, docks, airports, combined substations and other important places.

Our tramsformer features:

1, high-voltage winding with copper, low-voltage winding with copper or copper foil around the glass

fiber mat filled with a vacuum, with no filler of epoxy resin casting, curing to form a solid cylindrical

overall, mechanical High strength, local discharge is small, high reliability.

2, flame retardant, explosion-proof, do not pollute the environment. Winding coil of glass fiber and other

insulating materials with self-extinguishing characteristics, not because of short-circuit arc, high heat resin

will not produce toxic and harmful gases.

3, the coil does not absorb moisture, the core clip has a special anti-corrosion protection layer, can be 100%

relative humidity and other harsh environments. Intermittent operation to be tide treatment.

4, anti-short circuit, high impact level of lightning.

5, the coil inside and outside the side of the thin layer, the heat performance is good. The cooling method is

generally air free cooling (AN). For any degree of protection of the transformer, can be configured air-cooled

system (AF), in order to improve short-term overload capacity to ensure safe operation.

6, low loss, energy saving effect, run the economy, can be maintenance-free.

7, small size, light weight, less space, low installation costs, do not have to consider the drainage tank, fire and

fire facilities and standby power supply.

8, due to no fire off, the explosion of concern, can be dispersed in the load center, fully close to the electricity

point, thereby reducing the cost of the line and save expensive mortgage facilities costs.

Shell material is made of stainless steel or aluminum alloy. Protection class IP20 and IP23. IP20 shell to prevent

the diameter of more than 12MM solid foreign body into the transformer for further security protection. IP23 housing

also has to prevent the vertical line within 60 ° angle of water inflow, can be applied to outdoor operation.

Temperature control system by the temperature controller and installed in the hottest part of the product that is

the top of the low-voltage winding PT temperature components to achieve the temperature measurement and control

of the transformer, if the overload operation or failure caused by the transformer winding temperature is too high, the

temperature controller The alarm signal, the temperature exceeds the safe value will trip their own. When forced air

cooling is used by the temperature controller according to the winding temperature determines the cooling fan input

or switch.
