10KV High Voltage Ring Main Unit Inflatable Cabinet Outdoor Cable Branch Box

Product Introduction of 10kV High Voltage Ring Main Unit

Product Overview

10kV high voltage ring main unit is a modular, fully insulated distribution equipment designed specifically for urban power grid ring network power supply systems, suitable for distribution networks with 10kV voltage levels. Adopting SF6 gas insulation or solid insulation technology, it has the characteristics of compact structure, safety and reliability, and maintenance free, and is widely used for power distribution and protection in industrial parks, commercial centers, and residential areas.

Core Features

High security: Fully enclosed design, with a protection level of IP67, effectively isolating external environmental influences; Equipped with five prevention interlocking mechanisms to eliminate the risk of misoperation.

Intelligent control: optional FTU terminal, supporting remote monitoring, fault location, and automated operation, adapted to the needs of smart grid.

Flexible Expansion: The modular structure supports multiple circuit combinations (such as 2-6 units) to meet the requirements of different load scenarios for ring networks, terminals, or dual power access.

Environmental protection and energy conservation: using environmentally friendly insulation media (such as dry air or nitrogen), in compliance with green power equipment standards.
