Early Streamer Emission Lightning Rod

Product Details

Spain Nimbus Lightning Rod

CIRPROTEC, located in Barcelona, Spain, is a company with ninety years of history, specializing in the research, development, production, sales, engineering design, and construction of lightning protection products. It is also one of the world's leading manufacturers of early streamer emission (ESE) lightning rods, equipped with an advanced high-voltage laboratory and several world-class lightning protection experts and authorities.

The Nimbus series of early streamer emission lightning rods produced by Spain's CIRPROTEC utilize the company's proprietary, state-of-the-art electronic discharge technology. They feature an aesthetically pleasing design, compact and simple structure, and an extremely stable electronic discharge system. Easy to install, safe, and reliable, the products have been tested by third-party laboratories and comply with UNE21186-96 and NFC17-102 standards.

Since its market introduction in the late 1970s, the Nimbus series of early streamer emission lightning rods has seen steadily increasing sales, with annual sales exceeding 20,000 units in 2003. They are widely used for direct lightning strike protection in industries such as construction, electronic computing, telecommunications, broadcasting, television, and power supply. CIRPROTEC is committed to providing customers with the latest technology and comprehensive services.

Working Principle of Nimbus Early Streamer Emission (ESE) Lightning Rod

Due to the rise of large amounts of water vapor, charged clouds form at high altitudes. During a storm, a strong electric field (thousands of V/m) develops between the ground and the clouds. The ESE electronic triggering device has a system capable of storing some of this energy.

When the thundercloud begins its downward leader discharge, the number of electric ions in the field rapidly increases. The internal electronic system captures ions from the air and uses the previously stored energy to raise the voltage, releasing the buffering process. This causes the central part of the lightning rod to rapidly ionize the surrounding air and extend, generating an upward leader discharge and forming a discharge path.

The upward leader discharge produced and the downward leader discharge form a continuous discharge channel that meets the charged cloud, initiating the main discharge and diverting the lightning to the ground. The built-in electronic triggering system of the lightning rod rapidly increases the number of ions, allowing the upward leader to intercept the downward leader from the charged cloud hundreds of meters away from the rod. This results in a significantly larger protection radius for the lightning rod.
