Manual drive for isolator with earthing, under-line mounting, rotary motion of NRA E-12 w.II 03-507

Manual drive for grounded connector – reliable switching in overhead networks

This manual drive, designated NRA-u E-12 w.II (cat. no. 03-507), is a key element for safe and efficient switching in overhead lines. It is used to operate grounded connectors mounted under the line, providing reliable control of electrical circuits. It is particularly useful where several branches are required from a single spun pole that does not have mounting holes.

Functionality and application

This drive is designed for suspending pull-off and through-feed brackets that secure self-supporting insulated wires on spun poles. It enables safe and controlled connection and disconnection of circuits, which is essential during maintenance, repair work and when changing the network configuration. Thanks to its design, it allows for efficient operation even in difficult weather conditions.

Construction and assembly – for professionals and end users

The NRA-u E-12 w.II manual drive is compatible with connector drive mechanisms and is mounted with two M10 screws. This ensures a stable connection and precise control. The design allows for easy installation on both concrete and wooden poles, as well as on various types of supports. It is important to tighten the mounting screws properly to ensure the device operates reliably for a long time. The use of high-quality materials guarantees resistance to corrosion and mechanical damage.
