750 kva ~ 2500 kva 3 Phase Pad-mounted Transformer

A 750 kva ~ 2500 kva 3 phase pad-mounted transformer is a complete set of substation and distribution equipment that combines a combined transformer, a load switch and a protective fuse device for the high-voltage power receiving part, and the metering and switching of the low-voltage power distribution part.

The pad-mounted transformer has the characteristics of small size, low investment, convenient operation, fast installation, and simple maintenance.


2500 kVA Pad Mounted Transformer Features

1. Sub-box combination: high-voltage ring main unit and transformer sub-box, high-voltage ring main unit is composed of high-performance load switches with SF6 as insulation and arc extinguishing medium, which will not produce transformer oil when the load switches are opened and closed Any impact.

2. High safety: The high-voltage load switch has three positions of closing-opening-grounding, and has a reliable mechanical interlock. Only when the switch is in the grounding position can the fuse compartment be opened to replace the fuse.

3. Improve power supply stability: Since each load switch is independent, its operation will not affect other switches, and there will be no short-term power outage due to the switching of the power supply.

4. Reliable power supply: The high-breaking current-limiting fuse can reliably protect the transformer, and when a phase fuse is blown, the striker equipped with the striker will push the load switch tripping mechanism to open the load switch and avoid phase loss operation.

5. The ring network cabinet can be operated electrically to achieve remote control and meet automation requirements.

6. The ring network cabinet is equipped with a live display device, which can intuitively display whether the equipment is live or not. The device can also be used for phase verification and electrical inspection.

7. Go deep into the load center: reduce the power supply radius, save cable investment, and improve the quality of power supply.
