Product description
Product Introduction:
1250KVA oil-immersed transformer is our company introduced foreign advanced technology, independently developed SCB10, SCB11 series of thin insulated dry-type transformers with packing, because the coil is encapsulated by epoxy resin, so it is flame-retardant, fireproof, explosion-proof, maintenance-free, pollution-free, small size, can be directly installed in the load center. At the same time, the scientific and reasonable design and pouring process make the product have smaller partial discharge, low noise, strong heat dissipation capacity, and can run for a long time under 125% rated load under forced air cooling conditions, and is equipped with an intelligent temperature controller, with fault alarm, over-temperature alarm, over-temperature trip and gate function, and is connected to the computer through the RS485 serial interface, which can be centrally monitored and controlled.
Applications:
According to different use environments, shells with different protection levels can be configured or not configured, which are suitable for important or special environmental places such as high-rise buildings, commercial centers, airports, tunnels, chemical plants, nuclear power plants, and ships.

Normal conditions of use:
1. Indoor use, and the altitude is not more than 1000 meters.
2. Ambient temperature: maximum temperature +40°C, minimum temperature -30°C, maximum annual average temperature +20°C.
(If it does not meet the above conditions, it will be explained in detail at the time of ordering, and appropriate adjustments can be made according to the relevant provisions of the corresponding standards)
1. The high-voltage winding is made of enameled copper wire, and the low-voltage winding is wound with copper foil. The high-voltage winding is filled with glass fiber felt, and poured with imported epoxy resin without filler in a vacuum state, which forms a solid whole after curing, with good mechanical strength, small partial discharge and high reliability.
2. Flame retardant, explosion-proof, non-polluting environment, can be installed in the load center.
3. The coil does not absorb moisture, and the core and fixture can operate in 100% relative temperature and other harsh environments after special process treatment, and there is no need to remove moisture for intermittent operation.
4. High level of anti-short circuit and lightning impact.
5. The resin insulation layer on the inner and outer sides of the coil is thin and has good heat dissipation performance. The cooling method generally adopts air free cooling (AN). Transformers of any degree of protection can be equipped with an air-cooled system (AF).
6. Low loss, good power-saving effect, economical operation, maintenance-free.
7. Small size, light weight, small footprint, easy installation.
