Clamp for lightning protection installation ELKO-BIS JK-50/2 — JK-50/2, for conductor Ø up to 50 mm

ELKO-BIS clamp JK-50/2 is a compression/bolt clamp designed for lightning protection installations to connect, fix or terminate down conductors with diameters up to 50 mm. The clamp provides a stable mechanical grip and a low-resistance electrical connection suitable for earthing and grounding systems on roofs, masts and cable runs. Constructed for outdoor use, it facilitates joining conductors, creating secure terminations and maintaining continuity in external lightning protection systems.

Advantages

The JK-50/2 clamp offers robust mechanical strength and reliable electrical contact through its compression and bolt fastening method, ensuring consistent performance under tension and environmental exposure. Its capacity for conductors up to 50 mm diameter reduces the need for multiple connector types and simplifies installation of large-area down conductors. The design allows for straightforward mounting on typical lightning protection routes and provides corrosion-resistant properties suitable for outdoor installations.

Suitable for

• Joining large-diameter down conductors in external lightning protection systems
• Fixing and terminating conductors on roofs, masts and supports
• Creating continuous earthing paths in grounding networks

Key specifications

• Type: compression/bolt clamp for lightning protection
• Conductor capacity: accommodates conductors with diameter up to 50 mm
• Application environment: outdoor use on roofs, masts and cable routes
• Function: mechanical fixation and electrical continuity for earthing/grounding systems
• Material characteristics: designed for corrosion resistance suitable for external installations

How to use

Position the JK-50/2 clamp around the conductors to be joined or terminated, ensuring the conductor surfaces are clean and free of insulating coatings at the contact points. Tighten the bolt/compression mechanism according to manufacturer torque recommendations until the clamp secures the conductors without crushing them. Verify mechanical stability and electrical continuity after installation. When used on roof or mast installations, mount the clamp in accordance with the routing plan for the lightning protection system and local installation standards.

Usage recommendations

Inspect contact surfaces before assembly and remove paint or oxidation to ensure low-resistance contact. Use appropriate tools and torque settings to avoid over-compression. For long-term reliability, periodically check clamps in exposed locations for corrosion or loosening and re-tighten or replace as needed.
