AIR TERMINALS

The Air Termination Network (ATN) is a vital part of any structural Lightning Protection System.

The ATN is the part that arrests the lightning strike. An ATN can be designed through multiple methods: the “mesh”, the “protective angle method” and/or the “rolling sphere” or a combination. The adoption of which method(s) to use is very much determined by the nature of the structure to be protected.

An ATN may consist of:

  • Conductors laid in a mesh over the structure
  • Vertical Air Terminals (or Lightning Masts)
  • A combination of the two (particularly useful when protecting roof mounted plant)

An air termination network consists of the following elements:

  • Air Terminals (to intercept the lightning strike)
  • Conductor (for a safe path to earth for the lightning current)
  • Fittings (to fix the conductor to the structure) and
  • Bonding (to minimise dangerous side flashing to continuous metalwork within and on the structure)

The amount and type of material used in the Air Termination Network is dictated by the “Risk Assessment”, “Geometry of the Structure” and “Designer’s material preference”

CONVENTIONAL AIR TERMINALS

  • Air Terminals
  • Multi-Points
  • Strike Pads
  • Heavy duty wall mounting and hinged base masts

INSULATED LIGHTNING CONDUCTOR

The Interception Masts/Air Terminals in this section are specially designed to be used with the Kingsmill Insulated Lightning Conductor.

This system is ideal where space is in limited supply. Through using Insulated Lightning Conductor, the Air Terminal can be placed closer to the object to be protected – for example, roof-mounted plant or solar PV panels.

Kingsmill Insulated Lightning Conductor Cable is used for maintaining the separation distance between electrically conductive parts of the structure to be protected and the Lightning Protection System and is in accordance with IEC EN 62305-3.

LIGHTWEIGHT LIGHTNING MAST

Kingsmill bring innovation to lightning protection through the introduction of an easy to install, aesthetically pleasing Lightweight Lightning Mast.

Suited to projects using the “protective angle” or “rolling sphere” methods for determining zones of protection.

The conical design brings greater strength, wind loading capability and minimal wind deflection.
