Indelec Lightning Protection: ESE Terminals & Counters
Indelec Lightning Protection Systems: ESE Terminals & Counters
Indelec, founded in France, is a specialist manufacturer of lightning protection systems for industrial, commercial, and infrastructure applications worldwide. The company is best known for its Prevectron range of Early Streamer Emission (ESE) air terminals, which comply with NFC 17-102 and IEC 62305 international standards and are deployed on industrial plants, telecommunications towers, substations, heritage buildings, and critical infrastructure across more than 60 countries. Atlantech Drives & Controls has been sourcing and supplying Indelec lightning protection components since 2018 through an established network of international partners, serving electrical contractors, protection engineers, and procurement teams across the EU, the Americas, and worldwide.
Prevectron 3 ESE Air Terminals
The Prevectron 3 is Indelec’s flagship Early Streamer Emission air terminal, designed to provide a protection radius significantly larger than conventional Franklin rod systems of equivalent height. Available in multiple trigger advance times — including the Prevectron 3 TS10 and Prevectron 3 TS25 — the range covers protection radii from 20 to 107 metres depending on installation height and trigger advance time. The Connect series variants (TS10 Connect, TS25 Connect, S40, S50, and S60 Connect) incorporate integrated wireless connectivity for remote monitoring of strike activity and terminal status.
Lightning Counters & Strike Monitoring
Accurate strike counting is a mandatory element of NFC 17-102 compliant installations, providing maintenance teams with evidence of lightning activity and enabling inspection scheduling. Indelec offers three counter variants to suit different project requirements: the Digital Flash mechanical-electronic counter for standard installations, the Advanced Flash with extended data logging capability, and the RFID Flash counter which allows contactless data retrieval via RFID reader during inspection without the need to physically access the down conductor.
Air Rods & Specialist Mounting Solutions
Beyond the ESE terminal range, Indelec supplies conventional air termination components and specialist mounting hardware for non-standard installation environments. The stainless steel air rod for special chimney applications is designed for high-temperature and corrosive environments where standard aluminium or copper rods are unsuitable, making it the preferred solution for industrial chimneys, flue stacks, and process exhaust points in chemical, petrochemical, and cement manufacturing facilities. For heritage and architecturally sensitive structures, the Primer Heritage Building ESE terminal provides NFC 17-102 compliant protection with a discrete profile designed to minimise visual impact on historic facades.
Frequently Asked Questions
Q: Are Indelec ESE air terminals compliant with European lightning protection standards?
A: Yes. The Prevectron 3 range complies with NFC 17-102 (French standard for ESE systems) and is designed for use within the framework of IEC 62305 risk assessment methodology. Installation must be carried out by a qualified lightning protection engineer following a site-specific risk assessment.
Q: Can you supply individual Indelec components for an existing installation that requires a replacement part?
A: Yes. Atlantech supplies individual Indelec components including replacement ESE terminals, lightning counters, and mounting hardware for existing installations. Contact our team with the existing reference and installation details for availability confirmation within 24 hours.
