2. Scope
This document is limited to the type and installation requirements for all types of anti-climbing device, safety signs and
information labels required on overhead line supports up to and including 132kV.

This document shall be read in conjunction with Northern Powergrid policy document NSP/004/012 which provides
detailed information on the risk assessment of overhead lines and the recommended mitigation measures required.

This document has been designed to fully comply with ENA TS 43-90 Issue 6:2013.
