Epoxy Resin Pouring Transformer

PRODUCT OVERVIEW

Epoxy resin pouring transformer is a solid insulation encapsulated winding power transformer. Epoxy resin dry-type transformer uses epoxy resin as insulation material. High and low voltage winding is made of copper strip (foil), epoxy resin is poured and solidified in vacuum to form high strength FRP body. Insulation grade is F, and H. Epoxy resin dry-type transformer has the characteristics of good electrical performance, strong lightning shock resistance, strong short-circuit resistance, small size and light weight etc.. The temperature display controller can be installed to display and control the operating temperature of the transformer winding to ensure the normal service life of the transformer.

PERFORMANCE CHARACTERISTICS

1. No oil, no pollution, flame retardant, self-extinguishing and fire prevention;

2. Low loss, high efficiency and low noise.

3. Small local discharge (under 30 PC) and high reliability, can ensure long-term safe operation, life up to 30 years;

4. Resistance to crack and temperature change, high mechanical strength, strong ability to resist sudden short-circuit;

5. Good moisture-proof property, it can run normally under 100% humidity and can be put into operation without drying treatment after shutdown.

6. There is no need for a separate transformer room, core maintenance or load-bearing beam saving civil land and occupation No oil, so it will not produce toxic gas to pollute the environment. No need of oil collecting pits or other ancillary buildings which reduces the cost of construction;

7. Easy installation, no debugging, almost no maintenance; No need to replace or check the oil, low operation and maintenance cost.

APPLICATION  

Due to the coil is encapsulated by epoxy resin, epoxy pouring transformer is flame-retardant, explosion-proof, maintenance free, pollution-free, small in volume and can be directly installed in the load center. Meanwhile, the scientific and reasonable design and pouring technology makes the product partial discharge is smaller, noise is lower and the heat dissipation is stronger. It can run long time under 125% rated load under the forced air-cooling condition and is equipped with intelligent temperature controller. It is with the functions of fault alarm, over temperature alarm, over temperature trip and black gate, it is connected with computer through RS485 serial interface and achieves centralized monitoring and control. As the dry-type transformer produced by our company is with mentioned characteristics, it is widely used in power transmission and transformation systems in important sites such as hotels, airports, high-rise buildings, commercial centers, residential districts and so on, as well as harsh environment such as subways, smelters, ships, offshore drilling platforms, etc.
