Advantages
- Full insulation,full sealing,less maintenance,reliable guarantee of personal safety.
- Separate box structure can be adopted to avoid oil pollution in transformer tank.
- High pressure side adopts double fuse full range protection,greatly reducing the cost.
- The box body adopts honey comb double sandwich composite board,insulation and heat dissipation function.
- Low voltage side with electronic phase protection device,when abnormal voltage in the system,can quickly break the main switch.
Applications
Urban Power Distribution Networks
Industrial Parks

Frequently Asked Questions
Q1: How do you solve quality problems?
A: Just send us some detailed photos of the issue,and our technical and quality testing department will take a look.We will come up with a solution that works for you within two days.
Q2: Is the American Box Substation suitable for underground installation?
A: The standard version is really designed for above ground installation where it can get proper ventilation.If you need it underground, you are looking at some special modifications,like enhanced waterproofing and remote monitoring capabilities.Best to check with our engineering team to work out a customized solution.
Q3: How does the dual-fuse protection system work?
A: The high voltage side uses a dual fuse full range protection system,so one fuse handles overload protection and the other handles short circuit protection.That setup gives you comprehensive protection while keeping costs lower than what you would pay for a circuit breaker solution.
