Catalog Descripton:

Dry-type Transformers/20kV and 35kV SC(B) series dry-type transformers

Description:

This series of products are used to transform grid power of 20kV or 35kV directly to 400V distribution power or 10kV transmission power for supply to users. With significant advantages, they are employed in increasingly more projects. Major advantages include:

1. Reduced land occupancy in construction of multi-stage substation projects produces significant social benefits.

2. Requiring less investment in construction contributes to higher economic efficiency.

3. The 10kV transmission and transformation procedure is omitted, having significantly reduced the operation and maintenance cost.

4. Transmission at high voltage and low current instead of low voltage and high current reduces line loss and the line operation cost.

5. 35kV is directly connected to a power consumption center to effectively improve the reliability of power supply.

Product functions
The SCB series 35kV excitation-free voltage regulating dry-type transformers manufactured by our company are products of low loss, conforming to requirements of GB/T1094.11, GB/T10228 and IEC60076.11. These products have the following characteristics: High performance and low losses. Use of high-quality silicon steel plates to effectively reduce noise, magnetic flux density, and magnetostriction of the silicon plates during operation. Optimized high-voltage coil structure with better interlayer voltage and capacity distribution, having greatly enhanced the resistance of the products to atomospheric and operating over-voltage while improving the electric field distribution to further reduce the partial discharge of the products. Configurable temperature control system and air-cooling device which can be automatically started when the load is too high to enhance the overload capacity of the equipment.
