American Type Pad-Mounted Transformer / ZGS Combined Transformer

Product Overview

ZGS American Type Pad-Mounted Transformer (Combined Transformer) is an integrated outdoor prefabricated power distribution equipment. It integrates high-voltage load switch, dual-sensitivity fuses, oil-immersed transformer and low-voltage outgoing cabinet into one compact enclosure, adopting fully sealed & fully insulated oil-immersed design. It supports both ring network and terminal power supply modes, widely applied in urban power grid renovation, residential communities, commercial complexes, photovoltaic power stations, industrial parks and temporary construction power supply projects.

Core Product Advantages

1. Ultra-Compact Integrated Structure

All high-voltage protection components and transformer body share the sealed oil tank, the overall volume is only 1/3~1/5 of European type box substation with the same capacity, greatly reducing land occupation and civil construction cost. The integrated single-box structure simplifies transportation and on-site placement.

2. Full Insulation & High Safety Performance

Adopts fully insulated elbow cable connectors for high-voltage incoming lines; the outer surface of cable fittings is zero electrification and touchable for safe operation. Dual fuse protection (temperature & current dual-sensitivity plug-in fuse + current-limiting backup fuse) provides comprehensive overcurrent & overload protection to avoid equipment burnout risk. Three-point grounding design eliminates exposed live parts to prevent electric shock accidents.

3. Low Maintenance & Long Service Life

Fully sealed oil tank structure isolates insulating oil from air, effectively slowing oil aging; the transformer supports long-term maintenance-free operation. Standardized plug-in structure of fuses and cable terminals allows quick replacement of faulty parts without complex disassembly. The cold-rolled steel enclosure with anti-corrosion outdoor coating adapts to rain, dust and high-humidity outdoor environments.

4. Flexible Power Supply Compatibility

Supports two wiring schemes: ring main network and terminal single power supply, realizing seamless power switching to improve power supply reliability. The low-voltage compartment reserves abundant installation space for MCCB, multi-function meters, ATS and reactive power compensation modules, customizable according to user load requirements.

5. Excellent Transformer Performance

The built-in oil-immersed transformer adopts step-lap silicon steel sheet core, featuring low no-load loss, low operating noise and strong short-circuit & overload resistance. It allows long-time overload operation without shortening service life, stable for continuous heavy-load industrial scenarios.

Application Scenarios

Urban power grid renovation, residential quarters, schools, hospitals and commercial shopping malls;

Distributed photovoltaic power stations, wind farms and energy storage supporting power distribution;

Industrial factory workshops, mining enterprises and park power supply;

Temporary construction power supply for highways, tunnels, rail transit and municipal projects;

Rural power distribution network and street lighting centralized power supply.
