Sweden YB-12/0.4 Outdoor prefabricated substation (European style)
Category:
Product Description
Overview
YB-12 series outdoor prefabricated substation (European style) is a high-voltage switchgear distribution transformer and low-voltage distribution device, which are prefabricated indoor and outdoor compact distribution equipment arranged in a certain wiring scheme, that is, the functions of high-voltage power receiving, transformer, low-voltage distribution, etc. are organically combined together, and installed in a moisture-proof, rust-proof, dust-proof, rat-proof, fire-proof, anti-theft, gasketed, fully enclosed, movable steel structure or non-metallic box, and the mechatronics is fully enclosed and operated;
It is widely used in urban power grid transformation, residential areas, high-rise buildings, factories and mines, hotels, shopping malls, airports, railways, oil fields, docks, highways and temporary power facilities and other indoor and outdoor places.
