OP-type waterproof piercing branch clamps are designed for electrical connection of neutral and current-carrying cores of self-supporting insulated wires (SIP) when branching from the main line, suitable for both copper and aluminum conductors. They ensure reliable electrical contact and allow installation at temperatures down to -20 °C.

Design features:

• Shear head bolt: provides the necessary force to create a reliable electrical connection between the main line and branch conductors.
• Contact grease: applied to piercing elements to enhance connection quality.
• Ease of installation: clamps are easily mounted on the wire without loose components.
• Bolt insulation: the bolt is insulated from the contact parts of the clamp, increasing operational safety.
• Lower part fixation: the ability to fix the lower part of the clamp with a wrench (S 15 for OP 6 and OP 616; S 19 for OP 645 and OP 95) facilitates bolt tightening.
