This OPR range delivers improved performance in early streamer initiation and propagation, and represents further progress in terms of lightning protection, operating autonomy and ease of maintenance.

Small Equipment (No External Dimension More Than 50 cm)

ABB — already a leading global provider of lightning protection systems — reached a new milestone recently with the announcement that UL has granted certification for OPR 30, OPR 45 and OPR 60 Early Streamer Emission Air Terminals.

the OPR begins to get activated and generates high voltage pulses, helping to create and propagating an upward leader. After a strike on the OPR, the lightning current is driven to ground by the down conductor to the earth termination system. The OPR efficiency (ΔT) Lightning is one of the most spectacular meteorological phenomena. Generated

Lightning protection (strikes with indirect effects) for telecommunication stations by lightning arresters, is applicable for all electrical networks. It is also compulsory to provide protection against lightning strikes with direct effects by placing a lightning arrester (near the top of the.

The OPR Lightning Air Terminal uses Initiation Advance to make your lightning protection system even more effective. See how our OPR System helps protect your facility.

OPR air terminals are especially effective for the protection of classified industrial sites, administrative or public build-ings, historical monuments and open-air sites such as sports grounds. Lightning protection technologies

ABB have developed the OPR range of early streamer emission air terminals as an alternative to the Helita brand. These state-of-the-art technologies have been designed on the basis of a series of patents registered jointly by HELITA and the French …

OPR early streamer emission (ESE) air terminals are especially effective for lightning protection of industrial sites, administrative or public buildings, monuments and open-air sites such as sports grounds.

OPR 30 An OPR 30 is an ideal short range device and has the ability to protect against lightning in a range of 65 meters.
