Опис производа

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.
