Product Description
SF6 Load Break Switch Ring Main Unit RMU Switchgear Panel Cabinet
Insulation Performance: Utilizes SF6 gas as the insulation medium. SF6 gas has excellent insulation and arc - extinguishing properties, effectively ensuring the stable operation of the circuit breaker within the medium - voltage range of 12kV - 40.5kV, greatly enhancing the safety and reliability of equipment operation.
Rated Parameters: The rated current can reach 630A - 1250A, and the rated short - circuit breaking current can be up to 25kA - 31.5kA, which can meet the load requirements and short - circuit breaking requirements of different power systems.
Application Scenarios: Widely used in power distribution and control fields such as substations, industrial enterprises, and high - rise buildings. It can realize normal on - off control of the circuit and quick cut - off protection in case of short - circuit faults.
Structural Design: Adopts a metal - clad fully enclosed structure with an IP3X protection level, which can effectively prevent dust, small animals, etc. from entering and ensure the safe operation of the equipment. The cabinet door and the switch operating handle have a mechanical interlock function, ensuring that the cabinet door cannot be opened when the switch is in the closed state, and the switch cannot be closed when the cabinet door is open to avoid misoperation.
Performance Features: The load switch also uses SF6 gas for insulation and has the advantages of high parameters, maintenance - free, and pollution - free. It adopts a spring - energy - storage operating mechanism, equipped with three - phase free - release and five - proof interlock devices to ensure safe and reliable operation. The ring - main unit can be flexibly configured into a ring - main power supply unit or other wiring methods to adapt to different power grid layouts.
Technical Parameters: The rated voltage covers 12kV, 24kV, and 35kV, the rated current is 630A and 1250A, and the short - circuit withstand current is 25kA - 31.5kA. It has perfect safety protection functions and has no oil, non - toxic, no explosion, and no fire risks.
Application Scope: Suitable for medium - voltage power distribution and control in urban distribution networks, residential communities, commercial centers, etc. It can realize power distribution automation and improve power supply reliability and management efficiency.
