For 275kV and 400kV towers the comprehensive NGC specification for Anti-Climbing Devices introduced in 2002 is now universal. Essentially there are two formats. The All-Round type and the Single-Leg design for wide based towers.
Overhead Line Fittings (UK) Limited are the approved manufacturer of this equipment which is of substantial build to ensure the highest level of security. Items are normally available ex-stock. The designs embrace every variation of tower found on 275kV and 400kV construction and are installed using high specification stainless steel barbed wire. The standard specification employs nine strands of wire, which changes to ten strands when dressing towers with particularly large leg angles.
Barbed wire spacer bars are supplied to suit both configurations. Click here for Notification Plates, Stainless Steel Barbed Wire, Wire Ties, Hook Bolts and Step Bolts.
