Surge and Lightning Protection

A surge is a transient electrical fluctuation that happens in a fraction of a second and can cause serious damage to electronic and electro mechanical equipment.

They can be caused by lightning strikes and local power utility company "spikes" which can enter your business or home through the electrical system ie. cable television, telephone wiring etc and attack any electrical equipment attached to them.

Softwired Data Line Protection

Lightning and over-voltage transients are responsible for millions of dollars of damage each year affecting a wide cross section of industries.

Telecommunications sites are particularly vulnerable to the dangerous effects of lightning.

Many telecommunication installations consist of tall slender towers situated in elevated areas such as hill and mountain tops in regional areas and throughout metropolitan areas such installations can be found at the tops of tall buildings.

There is no single solution which can eliminate the risks associated with lightning induced energy.

It is through the use of an all encompassing approach such as the LPI 4 Step Approach to Lightning Protection which assists in significantly reducing the risks presented by the natural occurrence of lightning to a typical telecommunications site.
