Electrical continuity between the various parts must be
permanently guaranteed (e. through hard soldering,
welding, crushing, beading, screwing riveting).
Characteristic data that apply irrespective the

• Materials and their conditions use
• Materials, shape and minimum dimensions air-
termination systems, down-conductors and earthers
• Minimum dimensions connection cables
