American typepad-mounted transformer has the following main features.
◆Compact design
Small size, less floor space, suitable for places with limited space.
American box-type transformer structure is adopted, which is usually installed on a concrete Pad-Mounted.
◆Pre-assembled structure
Complete the integration of high and low voltage switches, transformers and protection devices before leaving the factory to reduce the workload of on-site installation.
Adopt fully sealed structure, moisture-proof, dust-proof and corrosion-proof.
◆Safe and reliable
Adopt full insulation design to reduce the risk of electric shock.
It has the functions of overload, short circuit and temperature protection, and runs stably.
◆Easy maintenance
American plug-in cable head (elbow cable head) is adopted, which is convenient for quick installation and replacement. The design of the access door is reasonable and convenient for operation and maintenance.
◆Strong adaptability
American Type Pad-mounted transformer is suitable for outdoor environment, the protection level usually reaches IP67.
Customizable design can meet different voltage levels (such as 10kV/0.4kV) and capacity requirements (such as 50kVA~1600kVA).◆
●Common application scenarios of American type pad-mounted transformer
✅Urban distribution network: it is suitable for power distribution transformation of streets and communities, and reduces the occupied area.
✅Residential area: quiet design, suitable for power supply in residential areas.
✅Commercial center: beautiful and compact, without affecting the city appearance.
✅Industrial Park: Adapted to harsh environment with high reliability.
✅Temporary power consumption: such as construction sites, exhibitions, etc., which is convenient for rapid deployment.
