Manual drive for connector with earthing, line-side mounting, rotary motion NRA E-10.5 w.I 03-502

Manual drive for connectors – a reliable mechanism for safe operation

This manual drive, model NRA-u E-10.5 w.I, is designed for operating grounded connectors mounted above the line. It enables smooth and precise operation of the connector, which is crucial both during installation and maintenance of the power grid. It is an essential element for service work and switching in medium-voltage networks.

Design and application

This drive is designed for mounting on spun poles that do not have mounting holes. Its design allows for effective suspension of pull-off and through-feed brackets, ensuring stable mounting of self-supporting insulated conductors. This makes installation quick and does not require additional pole modifications. The drive works with ON (OUN) III SA 24/4 type connectors, making it a universal solution for many applications. Mounting is done with two M10 screws, which simplifies the installation and disassembly process.

Key features and benefits

• Versatility: Compatible with various types of connectors (ON, OUN) and the possibility of mounting both horizontally and vertically.
• Durability: Construction made of high-quality materials ensures long-lasting and reliable operation in harsh weather conditions.
• Safety: Enables safe switching of power lines, minimizing the risk of failure and power outages.
• Easy installation: Simple mounting system with M10 screws shortens installation time and reduces labor costs.
• Cooperation with other elements: The ability to connect with surge arresters and cable head terminations increases the functionality of the system.
• Adapted to different conductor cross-sections: The current clamp allows connection of a link or conductor with a cross-section of up to 95 (120) mm².
• Mechanical strength: Provides 2000 Z/W (close/open) cycles, guaranteeing long device life.
• Overload protection: Withstands peak current of 40 kA and short-time current of 16 kA for 1 second, protecting the installation from damage.

The NRA-u E-10.5 w.I manual drive is a solid and reliable solution for professionals involved in the construction and maintenance of power grids. Its versatility and ease of installation make it an ideal choice for both installers and end-users looking for a safe and efficient way to operate grounded connectors.
