Substations
Prefabricated compact substations integrating MV switchgear, transformer and LV distribution — European box, American pad-mounted, Chinese multi-room and turnkey E-House layouts.
European-Type Substation (YB / YBM Box-Type)
A prefabricated compact substation in the European layout: MV switchgear (RMU), distribution transformer and LV switchgear housed in separate internal compartments within a single weatherproof enclosure. Type-tested as a complete assembly to IEC 62271-202 — the natural choice for IEC-signatory markets (Southeast Asia, Middle East, Africa). Handles larger transformer capacities than the American type — used for neighborhoods, hotels, large work sites, industrial parks and renewable plants.
American-Type Substation (ZGS Pad-Mounted)
A pad-mounted compact substation in the American layout, built around an oil-immersed transformer with the MV load-break switch and fuse protection immersed directly inside the transformer tank. A double-tank horizontal arrangement keeps HV and transformer sections independently maintainable. Fully sealed and insulated (no clearance required), occupying only ~1/3–1/5 of the footprint of an equivalent European box substation — ideal for residential areas, malls, airports, railways and renewable sites.
Chinese-Type Substation (YB / ZBW)
A prefabricated compact substation in the Chinese layout: a single outdoor enclosure partitioned into separate rooms — MV switchgear, transformer and LV distribution — each independently accessible. Offers a wide choice of MV switching configurations and the highest capacity ceiling of the three styles, suiting urban distribution, industrial parks and grid upgrades.
E-House — Prefabricated Modular Electrical Room
A factory-built, fully integrated electrical building (containerized or modular steel structure) housing MV/LV switchgear, transformers, control and protection, auxiliary power, HVAC and fire systems. Fully assembled and tested at the factory, then shipped as a turnkey unit — drastically cutting on-site construction time. Widely used in renewable-energy plants (solar / wind), oil & gas, mining and large industrial projects, especially in remote or harsh-environment sites across the Middle East and Africa.
