Introduction
This outdoor pad mounted transformer is built for installation outside, in a metal enclosure with an overhanging roof canopy, access doors and side ventilation louvers. Inside are the HV load switch, an oil-immersed transformer and LV distribution equipment, so one unit is placed on one foundation.
It is part of Gangheng's Transformer Substation range. For substation-level LV options, see Pad Mounted Substation. The appearance above is from the product photo; customized models may differ.
Operating Conditions
Check these before choosing a site for an outdoor pad mounted transformer:

Installation and Foundation
The brochure includes a reference foundation drawing, marked for reference only. It shows a reinforced concrete foundation, a 25×5 flat-steel earthing bar, 50×50×5 angle-steel cable supports, a sump pit and a louver (galvanized plate) detail. The quantity and position of HV and LV outgoing conduits are decided by the user. For project work, confirm the formal foundation drawing, cable entry positions and earthing requirements with our engineers.
