Structural characteristics of prefabricated substations
May 23, 2022
Prefabricated substations occupy less floor space, which can save expensive civil construction and land occupation costs. Because the substation equipment goes deep into the load center, the electric energy is transmitted through the underground cable, the power distribution equipment is in harmony with the surrounding environment, the installation and use are simple, maintenance-free or less maintenance.
Features of European box substation:
The biggest feature of the European box substation is the combination, that is, the transformer, the high and low voltage switchgear, the sub-high voltage room, the transformer room and the low voltage room are combined in one shell. The main circuit is connected by cables and busbars, and one or more transformers can be placed in a box. The product size varies greatly, and users can freely choose high and low voltage components, cabinet types, and transformer models.
Features of American box substation:
The design concept of American box substation is fully insulated, fully enclosed and maintenance-free. The biggest feature is integration. The high-voltage components and transformers are placed in the transformer oil tank, and the low-voltage configuration is also extremely simple. It has the advantages of reasonable and compact structure, small size, flexible installation, convenient operation and small footprint. It is especially suitable for the load center of the urban power grid to reduce losses and improve the quality of power supply.
