Description

The 10kV Normal Pressure Sealed Air-Insulated Switchgear / Ring Main Unit (Dual Circuit) is an advanced medium-voltage power distribution device designed for dual-loop power supply systems. Operating at a rated voltage of 10kV, it adopts a normal-pressure sealed structure with air as the insulating medium, eliminating the need for SF₆ gas or other pressurized insulating materials. This switchgear integrates the functions of power distribution, protection, and control, making it suitable for scenarios requiring reliable dual-circuit power supply, such as industrial parks, urban distribution networks, high-rise buildings, and key infrastructure.

Key Features

• Normal Pressure Sealed Design: Operates at atmospheric pressure with a hermetically sealed enclosure, preventing leakage risks associated with pressurized systems and ensuring stable insulation performance over long-term use.

• Air Insulation: Utilizes air as the insulating medium (no need for gas treatment or refilling), reducing environmental impact and maintenance costs while meeting eco-friendly standards.

• Dual Circuit Capability: Supports two independent power supply loops, enabling seamless switching between circuits to enhance power supply reliability and minimize downtime in case of single-loop faults.

• Compact and Space-Saving: Optimized structure with a smaller footprint compared to traditional switchgears (similar in size to conventional pressurized models), ideal for installations with limited space.

• High Safety and Reliability: Equipped with reliable mechanical interlocks and anti-misoperation mechanisms; all live components are enclosed to protect against moisture, dust, and corrosion, ensuring stable operation in harsh environments.

• Low Maintenance: Simplified operating mechanism with a long mechanical life (up to 10,000 operations), reducing the need for frequent inspections and on-site maintenance, thus lowering operational costs.

• Standardized Expansion: Designed for easy on-site installation and modular expansion, allowing quick integration into existing power grids and minimizing power outage time during upgrades.
