In today’s networks, we rely on complex digital switches which include components that are sensitive to interruptions in voltage and current caused by lightning, transient voltages, power crosses and other electrical hazards. In order to prevent these hazards from harming personnel, damaging expensive equipment, and cause system failures, installation of proven quality protection products is required throughout the network: from the central office, outside plant, and finally at the customer premise. Harmful transient voltages is derived from the following:
 Lightning - most common cause of electrical surge damage. It can enter your network telephone or power cables.
Power crosses - where a communication cable comes in contact with an electrical power line. The result is destructive AC current transferred into the network.
Electrostatic discharge - static shocks administered to communication circuits through the build up and discharge of energy in dry climates. The electrical field that surrounds a high voltage power facility within a building also causes this phenomenon.
Power induction - can occur where power cables and telecommunication cables run in close proximity with each other. This can result in a condition referred to as electromagnetic coupling where system transients are induced onto the telecommunications cable, which can result in excessive heating and fires in terminal equipment located at the cable ends.
Your emphasis should be on reducing installation cost while still providing a high quality standard of protection required by today’s’ electronic and digital offices. The outside plant portion of the network provides a link between the switching equipment and the customer premise. Surge provides the ‘protection element’ for the distribution cables as well as customer premise equipment. Surge supplies the industry with outside plant protection products, which include building entrance terminals, 5-pin protector modules and station protectors. |
