SCB11 Transformer

Product introduction

10kV grade SC(B)10, SC(B)11, SC(B)12, SC(B)13 type epoxy resin cast dry transformer, can be used as oil-immersed distribution transformer replacement products, is a variety of dry transformers in excellent performance products. Especially suitable for urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subways, stations, docks, airports, underground power stations, laboratories, combined substations and other important places.

Characteristics of the product

The 10kV class SC(B)10, SC(B)11, SC(B)12, SC(B)13 power transformers produced by our factory are the low noise and low loss resin wound injection coil dry transformers which have the product type certificate earlier in China. Due to the advanced design, high-quality materials, scientific formula, strict process and standard testing, the product has the following characteristics:

1. The high-voltage winding is made of copper wire, the low-voltage winding is made of copper wire or copper foil, the glass fiber felt is filled and wrapped, the epoxy resin is poured without filler under vacuum, and the solid cylindrical whole is formed after curing, with high mechanical strength, small partial discharge and high reliability.

2. Flame retardant, explosion proof, no pollution to the environment. The insulating materials such as glass fiber winding coil have self-extinguishing characteristics, which will not produce arc due to short circuit, and the resin will not produce toxic and harmful gases under high heat.

3. The coil does not absorb moisture, and the core clip has a special anti-corrosion protective layer, which can operate in relative humidity and other harsh environments. No dehumidification is required for intermittent operation.

4. High resistance to short circuit and lightning impact

5. Coil inside and outside the resin layer is thin, good heat dissipation performance. The cooling method is generally natural air cooling (AN). For transformers of any protection class, air cooling systems (AF) can be configured to increase short-term overload capacity and ensure safe operation.

6. Low loss, good power saving effect, economic operation, maintenance-free.

7. Small size, light weight, less space, low installation cost, do not need to consider oil drainage pool, fire protection and backup power supply.

8. Because there is no danger of fire and explosion, it can be dispersed in the load center and fully close to the power point, thereby reducing the line cost and saving expensive low-voltage facilities.

Shell protection device

The housing material is stainless steel or aluminum alloy. The protection level is IP20 and IP23. The IP20 housing prevents solid foreign objects larger than 12mm in diameter from entering the transformer

For further security protection. The IP23 housing also prevents the inflow of water droplets within 60° of the vertical line, making it suitable for outdoor operation.

Note: The IP23 housing will reduce the cooling capacity of the transformer, with a decrease of about 5% for small capacity and about 10% for large capacity.
