4-hole wire-bednarka B control connector for 30mm (copper) /CU/ AH03022

Lightning protection installation test joint – reliability and easy control

This test joint, designed for connecting lightning conductor wire to the earthing busbar, is a key element of any surge protection system. It allows for resistance to earth measurement without the need to disconnect wires, which significantly facilitates regular inspections and ensures system continuity. Made of copper, it is characterized by high conductivity and corrosion resistance, guaranteeing long-term and safe operation.

The use of high-quality brass for the production of screws and nuts ensures reliable connections, and the precise workmanship enables easy installation. The joint is compatible with wires with a diameter of 8 mm to 30 mm, making it a universal solution for various types of installations.

Construction and application

The joint consists of a copper housing and a set of screws (4xM6x16, 1xM10x16, 2xM8x20) made of brass. The construction with four holes provides a stable connection of the lightning conductor wire to the earthing busbar. It is intended for use in lightning protection systems for buildings and industrial facilities. It is ideal for use in places requiring regular inspection of the installation status, such as inspection boxes or earthing pits. Mounting at a height of approximately 1 meter above the ground facilitates access to the control point and minimizes the impact of weather conditions on its condition.
