Description

The 10kV (Three Circuits) Normal Pressure Sealed Air-Insulated Switchgear / Ring Main Unit is a high-performance medium-voltage power distribution solution engineered to support three independent power supply loops. Operating at a rated voltage of 10kV, it features a normal-pressure sealed enclosure that uses air as the primary insulating medium—eliminating the need for SF₆ gas or pressurized systems. This switchgear integrates switching, protection, and control functions, making it ideal for scenarios demanding robust multi-loop power distribution, such as industrial complexes, urban substations, commercial hubs, and critical infrastructure requiring redundant power supply.

Key Features

• Three-Circuit Configuration: Supports three separate power loops, enabling flexible power distribution, seamless load switching, and enhanced redundancy. This design minimizes downtime by ensuring continuity even if one loop requires maintenance or experiences a fault.

• Normal Pressure & Air Insulation: Operates at atmospheric pressure with air as the insulating medium, eliminating risks of gas leakage, environmental pollution, or the need for gas refilling. This reduces long-term maintenance costs and aligns with eco-friendly standards.

• Sealed Enclosure: A hermetically sealed structure protects internal components from moisture, dust, corrosive substances, and external debris, ensuring stable performance in harsh or variable environments (e.g., high humidity, industrial zones).

• Compact & Space-Efficient: Optimized modular design with a reduced footprint compared to traditional multi-circuit switchgears, making it suitable for installations with limited space, such as urban substations or indoor distribution rooms.

• High Safety & Reliability: Equipped with mechanical interlocks, anti-misoperation mechanisms, and visible isolation points to prevent accidental contact with live parts. The enclosed design also mitigates arc flash risks, enhancing operator safety.

• Low Maintenance: Simplified mechanical components with a long service life (up to 10,000 operations) and no need for gas monitoring or refilling, reducing operational disruptions and lifecycle costs.

• Scalable Integration: Compatible with smart grid systems, supporting remote monitoring and control. Its modular structure allows easy on-site installation and future expansion, adapting to evolving power distribution needs.
