Earthing and equipotential bonding for a wind turbine

The high level of DEHN product quality safeguards the mechanical strength and corrosion resistance of your plant. This secures the reliable function of the entire electrical installation and lightning protection system in the long term.

Connection elements which are capable of carrying short-circuit current ensure the safe contact of the earth-termination system with metal parts of the foundation and the main earthing busbar.

The protection concept

Product recommendations:

Here is a possible concept for earthing and equipotential bonding on the foundation.

A - Connecting clamp

Foundation earthing: Connects round and flat conductors in concrete foundations. Connects the reinforcements with round and flat conductors. Tested short-circuit current carrying capacity (50 Hz).

A - Round wire 10 mm St/tZn

Foundation earthing: Conductor material for use in lightning protection and earth-termination systems. Tested to DIN EN 62561-2.

A - Strip 30 x 3.-5 St/tZn

Foundation earthing: Strip material for use in lightning protection and earth-termination systems. Tested to DIN EN 62561-2.

A - Fixed earthing terminal type M V4A

Foundation earthing: Corrosion-resistant connection of the ring earthing.

B - Connection clamp with threaded bolt V4A

Ring earthing: Connection of round and flat V4A conductors to fixed earthing terminals.

B - Cross unit StSt V4A

Ring earthing: Corrosion-resistant connection of the individual ring conductors in V4A.

B - Stainless steel strip V4A

Ring earthing: Corrosion-resistant ring conductor in V4A.

C - Equipotential busbar StSt

Equipotential bonding: For equipotential bonding and protective/functional equipotential bonding.
