ZGS Series Outdoor Compact Pad-Mounted Combined T | RFQ Sourcing Details

The ZGS Series is an American-type compact pad-mounted combined transformer designed as a complete power transformation and distribution unit. Its stated configuration integrates the transformer active part with switchgear, fuses, a tap changer, a low-voltage distribution assembly, and associated auxiliary equipment.

Available configuration options include metering, reactive-power compensation, and low-voltage feeder circuits. The unit is described for AC 50 Hz, 6–10 kV distribution networks, with rated capacities stated from 63 to 1,600 kVA. It uses an oil-immersed, core-type transformer with separated windings.

The enclosure is described as fully enclosed and fully insulated. Connection options are available for radial and ring-main systems, supporting system changeover arrangements. Installation may be indoors or outdoors.

The compact format is intended to reduce the required installation footprint and simplify site installation, operation, and maintenance. Listed use environments include industrial parks, residential developments, commercial centers, high-rise buildings, and temporary construction sites.

These are general stated applications;suitability for a particular network or site must be established from project-specific electrical and environmental requirements. Procurement confirmation is required before specification or ordering.

Buyers should verify the required primary and secondary voltages, exact rated capacity, vector group, impedance, tap range and tap-changing method, insulation level, protection scheme, fuse and switchgear ratings, low-voltage feeder arrangement, metering requirements, and reactive-power compensation configuration.

The source information contains inconsistent phase and capacity descriptors: it identifies the unit as three-phase in one attribute, references single-phase usage elsewhere, states 63–1,600 kVA in the overview, and lists 100–1,600 kVA in another attribute. Confirm the offered nameplate configuration in writing.

Also confirm enclosure rating, site altitude, ambient-temperature limits, cooling designation, permissible temperature rise, sound level, loss values, short-circuit withstand data, applicable product standards, required test reports, and whether listed management-system certifications apply to the manufacturing organization rather than the individual transformer.

The stated overall specification is 2200 × 1500 × 1800, but the unit and measurement basis are not identified;obtain an approved dimensional drawing before planning foundations, clearances, lifting, or transport.
