Anti-Corrosion And High-Temperature630kva American Box-Type Substation
Product Description:
The American box-type substation arranges high-voltage, distribution transformers, low-voltage power distribution devices, and electric energy metering equipment into a compact power distribution device according to a certain circuit plan, with a small footprint.
Used in a three-phase AC system with a rated voltage of 10/0.4KV, as a complete set of substations for receiving and distributing electric energy.
It is suitable for urban public power distribution, high-rise buildings, living quarters, industrial and mining enterprises, oil fields and temporary construction of projects.
The technical performance of the product meets the requirements of JB/T 10217 and other standards.
Box-type substation, also known as prefabricated substation or prefabricated substation, is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device, arranged according to a certain wiring scheme, the factory prefabricated indoor and outdoor compact Power distribution equipment, which organically combines the functions of high-voltage power receiving, transformer step-down, and low-voltage power distribution, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulation, fully enclosed, movable The steel structure of the box, mechatronics, fully enclosed operation, especially suitable for urban network construction and transformation, is a brand-new substation that has emerged after the civil substation.
