Reliable energy supply for large shopping center
A secure power supply is indispensable for a shopping center. This is also the case for the New World shopping center in the Ningbo, Zhejiang Province. A transformer was needed to reliably transport electricity from a subway station to the shopping center – and fulfill an important prerequisite: high safety for people and the environment.
Normally, transformers are filled with mineral or silicone oil for electrical insulation and cooling. However if there is any leakage, it is harmful to the environment and easily combustible. With the transformer for the shopping center an alternative fluid had to be put in place that is on the one hand biodegradable, and on the other hand hardly flammable. However, the change of the insulation fluid calls for an expert to adjust the transformer to the specific characteristics of this component. Siemens Transformers has been driving this technology for decades and has profound expertise in the design and manufacturing of ester-filled transformers.
