Lightning suppression type lightning rod "Lightning Ball (ALB)"
Adoption of a double-structured three-dimensional capacitor suppresses lightning strikes. Patents obtained in Japan and Europe and the United States.
The "Lightning Protection Ball (ALB)" is a lightning protection device that, by attaching an insulator to the outer circumference of an electrode that also serves as a support, and covering the protruding part with a spherical electrode in a double structure, generates negative charges above it as the positive charge on the ground increases, thereby suppressing lightning strikes. It has over 3,400 installations in Japan (as of 2020) and has pursued the prevention of "welcoming discharge" by further narrowing the area of positive charge compared to the conventional "PDCE Lightning Rod." It has also achieved improvements in the strength of the electrode. 【Features】 ■ Can be used as a lightning receiving part under the Building Standards Act ■ No power supply required / grounding is necessary ■ Minimal maintenance costs and effort ■ Patent application No. 2019-175708. Patents obtained in the U.S. and Europe ■ Performance verified through discharge voltage testing according to French standards (NF C17) Lightning Protection Ball (Large): Diameter 200mm / Height 390mm / Weight approximately 5.5kg Lightning Protection Ball (Small): Diameter 120mm / Height 235mm / Weight approximately 2.2kg *Please feel free to contact us for inquiries about installation.
