YBD Pre-installed Underground Box Variable
Pre-installed underground box variable is our company advocates green power, optimise the urban environment under the concept of learning advanced technology from abroad, into the modern urban ecological design concept, and gradually bury the transformer into the underground installation. Buried Transformer. Also known as underground transformer instrument, the domestic put this kind of transformer, high-voltage load switch, fuse, etc. placed in the oil tank of the compact substation equipment called underground combined transformer. It is installed in the pit, does not occupy the surface space, and can be diffused in the water operation for a period of time. It is suitable for urban residential areas, industrial parks, urban traffic in the main road and other urban power distribution network. The use of underground transformers can save the footprint of urban distribution facilities and improve the urban land use rate. However, the isolated underground transformer does not solve the problem of low-voltage configuration, so the promotion in China is greatly affected. With advanced technology, our company has crafted a new generation of underground power distribution equipment, a pre-assembled underground box transformer. This product consists of underground combined transformer, outdoor low-voltage cabinet, light box type low-voltage protection shell and prefabricated underground combined transformer base, is pre-assembled in the factory completed underground power distribution equipment, can also be increased according to user demand light box type cable branch box and light box type high-voltage measurement, for 10KV power distribution to provide a complete solution. Provide pre-assembled underground box for the urban power grid into the ground transformation provides a new and reliable technical equipment, in the environmental constraints, land, housing tighter areas of the power grid transformation of favourable conditions are mainly used to replace the traditional form of civil substations, European box variable, American box variable, power transformation, power distribution function of the new power products.
