Triangular Ring Main Unit Cabinet

Triangular ring main unit cabinet is a compact medium voltage ring main unit with a triangular structure design. Compared with traditional rectangular ring main units, it saves installation space and is suitable for compact power distribution environments.

With 9 years of experience in medium voltage equipment manufacturing, our factory has a 2,000㎡ standardized sheet metal production workshop and 40–50 professional technicians. We independently complete cabinet fabrication, assembly, and testing. We support customized production based on customer drawings or samples, with a minimum order quantity of only 1 set.

Each triangular ring main unit cabinet passes 100% inspection before shipment, including withstand voltage and circuit resistance tests. Third-party inspection is fully supported, and every unit comes with a 1-year warranty. If any cabinet deformation or component damage occurs during overseas transportation, we will evaluate the damage and provide original replacement parts.

The compact triangular structure allows flexible installation in limited spaces such as underground distribution rooms, prefabricated substations, and small photovoltaic projects. The IP33 protection design is suitable for indoor medium voltage distribution applications and has been exported to residential communities, solar projects, and commercial power systems in overseas markets.

Standard products support 30% advance payment with balance before shipment. Customized triangular ring main unit cabinet requires a 50% deposit before production. Large-volume customers can receive preferential pricing and priority production. Production updates, including cabinet forming, switch assembly, and functional testing, are provided through photos and videos.
