Manual drive for a connector with earthing, above-line mounting, rotary motion of NRA E-13.5 in.I 03-510

Manual drive for overhead line connectors – reliable operation and safety

This manual drive, designed for connectors with grounding, is a key element ensuring safe and efficient operation of distribution devices in overhead lines. Mounted above the line, it enables smooth rotational movement, which translates into precise control of the connector. It is an ideal solution for both professional installers and end-users responsible for maintaining energy infrastructure.

Design and application

The NRA-u E-13.5 drive is designed to work with three-pole disconnectors and disconnector-earthing switches manufactured by ALPAR. Its construction is based on a solid mounting, which ensures stability during operation. Mounting is done with two M10 screws, which simplifies and speeds up installation. This drive allows for manual control of the connector, which is particularly important in emergency situations or during maintenance work, where access to power may be limited. This allows for quick disconnection of a damaged section of the network or safe repairs.

Advantages and benefits

• Versatility: Compatible with various types of ALPAR overhead line connectors (ON, OUN, ONp, OUNp, ONM, OUNM, ONMp, OUNMp) III SA 24/4.
• Simple installation: Mounting with standard M10 screws minimizes installation time and does not require specialized tools.
• Safety: Enables manual control of the connector in emergency situations or during maintenance work.
• Durability: Solid construction guarantees long-lasting and reliable operation in various weather conditions.
• Synchronization: Ensures simultaneous closing and opening of all poles of the connector thanks to a common drive mechanism.
• Corrosion protection: Zinc coating made by hot-dip method protects against the negative impact of external factors.
• Connection flexibility: Possibility of connecting a link or a cable with a cross-section of up to 95 (120) mm² thanks to the use of a current clamp.

The NRA-u E-13.5 manual drive is an investment in the safety and reliability of energy infrastructure. Its solid construction and ease of installation make it an ideal choice for both professionals and those responsible for maintaining the efficiency of power networks.
