Document Type and Number:
WIPO Patent Application WO/2008/026766
Kind Code:
A1
Abstract:
A lightning arrestor (1) for flowing the thunder surge current due to lightning
strike (7) to the ground comprises a steel pipe (3), a conductor (4) coaxially
disposed in the steel pipe (3), an a filler (10) placed between the steel pipe (3)
and the conductor (4) and having a conductivity. With this, the thunder surge
