A pad-mounted transformer is basically a ground-level power unit that takes in high-voltage lines and brings them down to a lower level so shops, houses, or small factories can actually run their lights and machines. You’ll spot them in residential streets, tucked behind supermarkets, or even next to a petrol station. Compared to a full-size electric power substation, it’s small, sealed, and doesn’t need a huge fenced yard. Sometimes folks don’t even notice it’s there—it just looks like a green box on the curb.

Normally, 20–30 years is realistic. Some units even go beyond that if they aren’t constantly running at full load. The sealed oil tank helps a lot—it keeps out rainwater and dust. Unlike the old open-type gear, you don’t need to check every week. A quick inspection now and then really saves you headaches later.

Yes, and that’s exactly why developers use them. The cabinet is locked, fully sealed, and designed so nobody can reach in and touch the live parts. SHENGTE’s outdoor power distribution box meets strict insulation and protection standards.

There’s a wide spread. Smaller pad-mounted transformers around 125 kVA are enough for a residential block, while bigger ones like 1600 kVA can carry a medium-sized shopping center with lifts, escalators, and air-conditioning running full blast. In industrial parks, you’ll see multiple box-type transformers side by side to balance the load. If you’re not sure what size you need, share your load data—we usually help customers figure it out.

Sure. Some projects just need a standard unit, but others ask for adjustments: maybe a special voltage ratio, or integrating metering inside the low-voltage chamber, or matching the look of an outdoor pad-mounted transformer.
