## Summary description

ELKO-BIS JK-50/3 is a compression clamp designed for lightning protection and earthing systems. The clamp secures air-termination and earthing conductors, providing a reliable mechanical and electrical connection. Suitable for use on compatible conductor sizes and materials in external lightning protection installations and earthing networks where a robust, permanent joint is required.

## Long description

ELKO-BIS JK-50/3 is a compression clamp designed for lightning protection and earthing systems. It secures air-termination and earthing conductors to create a durable mechanical and electrical connection suitable for external lightning protection installations and earthing networks. The clamp is intended for use where a permanent, low-resistance joint is required between conductors or between a conductor and a structural attachment point, ensuring continuity of the lightning protection or grounding system.
Advantages
The compression design provides a stable, vibration-resistant connection that maintains good electrical conductivity over time. Manufactured to fit compatible conductor sizes and common materials used in lightning protection, the clamp offers straightforward installation without soldering or welding. Its construction minimises the risk of loosening and corrosion at the joint when installed correctly in outdoor lightning protection and earthing applications.
Suitable for
Securing air-termination conductors in external lightning protection systems
Creating permanent joints in earthing and grounding networks
Connecting conductors of compatible cross-sections and materials where a compression clamp is specified
Outdoor installations requiring a robust mechanical and electrical bond
Key specifications
Type: compression clamp for lightning protection and earthing conductors
Application: external lightning protection systems and earthing networks
Connection: mechanical compression joint providing low electrical resistance
Compatibility: designed for use with specific conductor sizes and common conductor materials used in lightning protection
Durability: intended for permanent outdoor installations when properly installed
How to use
Position the conductors within the clamp according to the conductor size compatibility and then apply the specified compression force using appropriate tools to achieve a secure joint. Ensure conductor strands are clean and free of coatings or corrosion that could affect electrical contact. After compression, verify mechanical tightness and continuity with a suitable electrical tester to confirm a low-resistance connection as part of the lightning protection or earthing system commissioning.
Usage recommendations
Use the clamp only with conductor sizes and materials listed by the system design, and follow local standards and manufacturer instructions for lightning protection and earthing installations. For best long-term performance, inspect joints periodically for corrosion or mechanical damage and retighten or replace components as needed during system maintenance.
