OR 72 and OP 74 types of waterproof piercing branch clamps are designed for electrical connection of subscriber branches to the neutral and current-carrying cores of the main line of self-supporting insulated wires (SIP) in 0.4 kV overhead power lines (VLI).

Design features:

• Separate bolt tightening: allows for multiple connections and disconnections of subscriber wires without removing the clamp from the main line.
• AG-type waterproof adapters: enable the connection of one to four subscriber branch wires.
• Contact grease: applied to piercing elements to enhance the quality of the electrical connection.
• Insulated bolt: the bolt securing the clamp to the main line is insulated from the contact parts of the clamp, increasing operational safety.
• Ease of installation: the clamp is easily mounted on the wire without loose components, and the ability to fix the lower part of the clamp with an S17 wrench facilitates bolt tightening.

The products are manufactured in accordance with technical specifications TU 3449-004-52819896-2010.
