What is the purpose of a riser pole?

A riseris an electrical connection attached to the side of a pole; hence, a pole supporting a riser is called a riser pole. The riser provides a connection between aerial conductors and underground conductors. The riser conductors are usually protected by conduit, although a U-guard is sometimes used.

Some utilities in this market use 5kA arresters on terminal poles, and some utilities use station class arresters on the riser pole. In a sense, these are also riser pole arresters. In the IEC market, it is quite common to use a class 2 arrester at terminal poles.

They get their name because of the way riser cable is ran which is rising up to each floor. Riser cable is important in that it can be a buildings backbone that transmits data, audio and video signals. The way Riser cable is termed through the industry is "CMR" which stands for communications riser.
