The KXAIS-12 series Solid Insulated Ring Main Unit Rmu Electrical Switchgear is a fully insulated, fully sealed, and anti condensation ring main unit equipment that is based on solid sealing and vacuum insulation technology, and is independently developed using epoxy resin (APG process) to pour the three position switch (isolation, grounding), circuit breaker vacuum arc extinguishing chamber, and main circuit primary conductive components together to form the insulation component body. It is assembled from insulated busbars and other insulation connectors to form a fully insulated, fully sealed, and anti condensation ring main unit.

The outdoor oil-immersed transformers at 10kV, 20kV, and 35kV levels have an advanced design with improved performance characteristics. They feature a unique structure with three core columns arranged in an equilateral triangle configuration. These gaps within the magnetic circuit, along with a core column loss, help reduce noise levels and ensure better balance of the transformer components. Additionally, these transformers effectively minimize the presence of the third harmonic component. They are suitable for various applications, including urban and rural areas, industrial and mining power grids, and are particularly well-suited for combination transformers and pre-installed substations.
