When lightning strikes a communications tower current flows to ground via the tower leg steel work and via any feeder cables that exist on the tower. It is impossible to sufficiently insulate these coaxial feeders or waveguides from the tower to prevent a flashover.
Features of the EKIT-1, EKIT-2 and EKIT-3 Coaxial Cable Bonding Kit:
Cable earthing kits are installed at the tower top, at the bottom of the tower on the vertical section immediately before the cable turns onto the horizontal cable runway and at the cable entry point.
The Cable bonding kit optimises the lightning current flow direct to ground and not into the equipment building.
Cable earthing kits connect coaxial cable sheaths and waveguide to the tower frame. No other earthing other than direct to the tower structure is required.
When protecting signalling systems it is vitally important to remember that protection is also required for the incoming power lines. Novaris is able to offer a comprehensive range of surge filters from 2A to 2000A per phase.
Surge filters provide highly reliable and effective surge protection for even the most sensitive electrical and electronic equipment. For further details on the full Novaris range of surge filters please contact Novaris or visit our website at http://www.novaris.com.au
Novaris has designed and manufactured lightning and electrical disturbance protection systems since 1993. We specialise in the protection of power and data signalling. Our products are in use locally, nationally and internationally, and we are now world leaders in lightning and surge protection technology.
At our Australian headquarters we operate a full time research and development group, employing professional engineers, technical officers and drafting support staff. Our testing laboratory is capable of generating and measuring simulated lightning impulses in accordance with world power and telecommunications standards. We also have offices and distributors throughout Australia and worldwide.
We design, supply and provide advice on structural lightning protection and earthing systems for all structures in accordance with recognised world standards. Our products range from main switchboard and distribution board surge protection, PLC and control system protection, to RF coaxial cable and telecommunications protection.
Our quality, performance and reliability is second to none.
