YBM-12/630 Modular In | RFQ Sourcing Details

The YBM-12/630 modular in t of assembly, wiring, and commissioning required at the project site. Its described internal scope combines high- and medium-voltage switchgear, a distribution transformer, low-voltage cabinets, control and protection equipment, monitoring, ventilation, heating, and fire-protection systems.

The listed transformer configuration is a three-phase, dry-type, core-type, multi-winding unit with a 100 kVA rated capacity, 0.4 kV low-voltage rating, 4% impedance voltage, 50/60 Hz frequency, and Class F insulation.

The enclosure is described as stainless steel, while the cabin structure is described as a fully welded steel construction with three-layer composite walls. Internal equipment is stated to be assembled, wired, debugged, and tested before shipment.

Horizontal and vertical modular combinations and non-standard customization are available. Standard cabin schemes range from 6.058 m to 12.192 m in length, with 2.5 m or 2.8 m widths and a listed height of 3.2 m.

Auxiliary provisions may include air conditioning, lighting, fire extinguishing equipment, anti-static flooring, drainage, heat dissipation, gas detection, ventilation, and remote monitoring, control, and protection systems.

Buyers should define which of these systems are included in the quoted configuration rather than assume every listed feature is standard.

The product is presented for power distribution projects involving factories, high-rise buildings, hydropower stations, renewable-energy facilities, industrial and mining sites, municipal distribution networks, ports, railways, highways, offshore platforms, field engineering, and temporary-power projects.

Suitability for any particular installation depends on the final electrical design and environmental requirements.

Procurement confirmation: Ask the supplier to provide the project-specific single-line diagram, equipment list, transformer and switchgear ratings, incoming and outgoing circuit details, protection scheme, control voltage, cable-entry arrangement, auxiliary-system scope, and approved general-arrangement drawing.

Confirm the required cabin dimensions, transport split, lifting points, site access, foundation interface, installation method, and commissioning responsibilities.

The source information gives conflicting enclosure protection grades—IP56 in the basic specifications and up to IP54 in the feature description—so the contractual IP rating must be resolved in writing.

Buyers should also confirm ambient temperature, altitude, humidity, pollution level, seismic requirements, wind loading, rain exposure, fire requirements, and whether coastal corrosion or salt-fog protection is needed.

Request the applicable certification documents, inspection and test plan, routine test records, packing method, delivery schedule, warranty terms, spare-parts list, and after-sales scope before placing an order.
