1500 KVA Substation Transformer

Henan GNEE Electric Co., Ltd. is one of the most reliable manufacturers and suppliers of 1500 kva substation transformer in China. If you're going to buy customized 1500 kva substation transformer made in China, welcome to get quotation from our factory. Quality products and reasonable price are available.

A Substation Transformer is designed for installation on three-phase transmission and distribution systems. Substation transformers are constructed for in-door or outdoor mounting on a concrete pad with high and low voltage cables entering operating compartments through enclosed sidewall mounted bushings (unit-type transformers) or through cover or sidewall mounted bushings (opentype transformers).

Substation Transformer Specifications

1. Advanced water-cooling system

Operation of a transformer in an underground cavern always increases the demand for its cooling capabilities. For these transformers, that withstand increased levels of voltage and load, traditional air-cooling was not sufficient. As a solution, an advanced water-cooling system was designed and built.

2. Powerful and compact go well together

When installing a transformer bank of three 500-kV autotransformers, size is always an issue. This is even more important when the transformer is located under the streets of a megacity. The overall size of the units, how - ever, is considerably compact, measuring just 9 x 5.6 x 7.3 meters (L x W x H) each.

3. Impedance reach losses

Not only were the specifications in terms of voltage level extraordinary, the requirements for short-circuit strengths were also more demanding than usual. Each transformer should withstand a certain amount of short-circuit load. However, the autotransformers for the underground substation in Shanghai can stand impedance of up to 22 percent. This means that the units will operate as usual even when exposed to a load 22 percent higher than their rated current.

4. Control of hot spot and excessive losses

High impedance presented challenges for hot spot and stray loss control. Fully supported by a 3D magnetic model tool, the shielding structure design, especially on the tank and clamping frame, increases overall efficiency.
