Dehn + Soehne 923045 AL EXFS L300 KS connection cable Cu 25 mm² L300 mm spark gap EXFS 100 content_copy

The connection cable AL EXFS L300 KS from Dehn + Soehne is a specific accessory for the EXFS 100 spark gap. It serves as a connecting element between the spark gap and the grounding system or other electrical installations. The cable is made of copper, has a conductor cross-section of 25 mm², and a total length of 300 mm. It is designed for parallel mounting on the EXFS 100 spark gap and is supplied with two cable lugs made of Cu/gal Sn, ensuring a secure and durable electrical connection.

Applications
This connection cable is used in electrical installation and grounding technology, particularly in systems where an EXFS 100 spark gap is installed. It enables a safe and conductive connection between the spark gap and the grounding network or other metallic conductors. The cable is used in industrial, commercial, and technical installations where reliable grounding and potential equalization are required to divert overvoltages and electrical disturbances.

Functions and Features in Detail
The cable is made of copper with a galvanized tin coating (Cu/gal Sn), ensuring high electrical conductivity and corrosion resistance. The two cable lugs, with a diameter of 10.5 mm, are designed for attachment to screw terminals or other connection elements. Additionally, the package includes a screw, nut, and spring washer to ensure a mechanically stable and electrically conductive connection. The 300 mm length allows for flexible installation without excessive tension or bending of the cable.

Technology Explained Simply
The conductor cross-section of 25 mm² ensures sufficient current-carrying capacity and minimizes resistance, which is important for efficient diversion of overvoltages and interference currents. The use of copper as the conductor material ensures high electrical conductivity, while the galvanized tin coating protects the surface from oxidation and corrosion. The cable lugs with a 10.5 mm diameter fit standard screw terminals and allow for secure mechanical fastening. The spring washer ensures constant pressure and prevents loosening of the connection due to vibrations or thermal expansion.

Compatibility and Accessories
The connection cable is specifically designed for the EXFS 100 spark gap and is mounted in parallel to it. It is part of the grounding system and serves to connect the spark gap to the grounding network or other metallic conductors. The combination with the EXFS 100 enables safe potential separation and protects the system from overvoltages. No other accessories are mentioned in the source material that are specifically designed to be combined with this cable.

Installation and Mounting
Installation involves attaching the cable lugs to the corresponding connection points on the EXFS 100 spark gap and to the grounding network or another metallic conductor. The included screw, nut, and spring washer ensure a secure connection. The cable is designed for parallel arrangement, allowing it to be installed without additional bends or tension. The 300 mm length provides sufficient clearance for installation in various system configurations.

Operational Advantages
The connection cable provides a reliable and durable electrical connection, which is essential for the function of the EXFS 100 spark gap. The use of copper with a tin coating ensures high corrosion resistance, extending the cable’s service life. The included fastening elements ensure a mechanically stable connection that remains secure even under stress from vibrations or temperature fluctuations. The parallel mounting simplifies installation and reduces the risk of incorrect connections.
