Load Break Switch

In medium-voltage power systems, a Load Break Switch (LBS) is a critical device used for switching under load, isolating fault areas, and ensuring safety during maintenance and operation.

NOVAw is a premium SF₆-insulated Load Break Switch series manufactured by Eaton’s Cooper (China), specifically designed for 24kV and 38kV medium-voltage systems. Featuring six integrated voltage sensors, SCADA communication capabilities, and flexible operation within ring main units, this product perfectly meets the demands for automation, monitoring, and stable operation in modern electrical projects.

Key Features:

• NOVAw utilizes SF₆ gas for both insulation and arc quenching, providing stable switching performance in high-voltage environments. SF₆ gas possesses strong dielectric properties and rapid cooling capabilities, reducing arcing during load switching, which protects the equipment and enhances operational durability. This is an ideal solution for areas requiring high reliability, such as substations, industrial zones, and urban technical infrastructure.
• The device is integrated with six voltage sensors, allowing for precise monitoring of the voltage status at both ends of the equipment. This is particularly crucial in ring main networks, where bidirectional monitoring is mandatory to ensure rapid fault handling and maintain system stability. The sensors also support data collection for more effective grid management.
• The control cabinet accompanying the NOVAw load break switch is fully equipped with protection, measurement, and remote control functions. Notably, the system supports SCADA connectivity via standard protocols such as IEC 60870-5-101/104 and DNP, facilitating seamless integration into DAS automation systems and enhancing the monitoring and operational capabilities of modern medium-voltage distribution grids.
• With a configuration compliant with IEC 62271-103:2011 & IEC 62271-200:2011 standards and type-tested at KEMA Lab (STL), the product ensures reliability and long-term operational performance. The optimized modular design allows for easy installation on poles or within substations, making it suitable for both limited spaces and future expansion requirements.

Practical Applications

NOVAw load break switches are effectively applied in various medium-voltage power systems:

• Medium-voltage distribution grids (22kV, 24kV, 35kV, 38kV)
• Industrial zone substations, RMU stations
• Sectionalizing points on ring main networks
• Control cabinets and Recloser, LBS switching devices
• SCADA – DAS systems in the power industry
• Renewable energy projects: solar power, wind power
