DOWN CONDUCTOR CONNECTION SYSTEM, WIND TURBINE LIGHTNING PROTECTION SYSTEM, AND METHOD FOR ARRANGING A DOWN CONDUCTOR CONNECTION SYSTEM

摘要

The present invention relates to conductor connection system for a wind turbine lightning protection system adapted to protect a wind turbine blade from lightning strikes. The lightning protection system comprises a down conductor cable adapted to extend in a longitudinal direction of the wind turbine blade and arranged for connection to the root end of the wind turbine blade, and comprises a number of lightning receptors electrically connected to and distributed along the length of the down conductor cable. The down conductor connection system comprises a modular down conductor cable having a first and second down conductor cable part, and at least one down conductor connector arranged between and connected to the ends of the down conductor cable parts. The down conductor connector comprises first and second terminals, connected to an end of each down conductor part, respectively, where the first and second terminals are adapted for mutual connection.
