e. addition, the EMC re-
quirements play ever greater role.
To implement insulated external lightning protec-
tion system, metallic conductors can applied
through insulators, such GFK bracket units, a
separation distance (s) according IEC/EN 62305-3.

Definition the separation distance for insulators
This separation distance (s) can also achieved
through high-voltage-resistant insulated conductors,
whereby the high-voltage-resistant conductor can be
routed directly the surface the structure.2. The image

Increasingly, structures, the electrical equipment is
being moved onto the roof. Such insu-
lated structure required, for example, the structure
or part the structure should not carry lightning cur-
rent, but located the protection area the insu-
lated external lightning protection system.
