Product overview

The high voltage ring distribution cabinet is a fully insulated and fully sealed medium voltage switchgear that integrates load switches, disconnectors, earthing switches, protection devices and intelligent units. It is specially designed for distribution networks with voltages of 10–24 kV and is the main element of ring power supply systems and radial distribution networks. Due to its high reliability, safety and flexibility, this equipment is widely used in urban power grids, industrial parks, shopping centers and renewable energy projects as distribution nodes, providing power reception, distribution, control and protection.

Key Features and Benefits

1.Full insulation and complete sealing - safety and environmental friendliness. Using SF6 insulation or environmentally friendly solid insulation technology, all high-voltage live parts are sealed in a gas-filled compartment or housing filled with epoxy resin, which completely eliminates the influence of the external environment (condensation, pollution, salt spray, small animals).

2. The absence of exposed live parts completely eliminates the risk of electric shock to personnel, ensuring extremely high safety. SF6 gas has excellent arc extinguishing and insulating properties, guaranteeing reliable switching.

3.Modular design - flexible expansion. The standard modular block structure (input block, outgoing block, metering block, voltage transformer block, etc.) can be flexibly combined according to the actual needs of power distribution, which is convenient for subsequent line expansion and circuit changes, and also greatly increases the flexibility of power supply planning.

4.Intelligent integration - efficient operation and maintenance. The equipment can be equipped with intelligent control devices, microprocessor protection devices and communication interfaces for monitoring current, voltage, position of switching devices, cable temperature and other parameters in real time, and also supports functions of remote control, tele-alarm and telemetering (telemechanics). Automatic fault detection, localization and isolation are realized, distribution automation (DA) is supported, which greatly improves power supply reliability, reduces power outages, and lays the foundation for the implementation of smart grid.

5.Maintenance-free design, long service life, high reliability. The main circuit is made in a maintenance-free design, all switching components are hermetically sealed and are not affected by the environment, have a long mechanical life and are stable in operation, which significantly reduces operating and maintenance costs throughout the entire life cycle.
