Aerial Installation 6.1
Overview
Aerial Installation
There are many applications for aerial conduit, some of which are road crossings, rail crossings, trolley line crossings,
and water crossings. Aerial conduit provides an efficient means for supporting cable and is easily accessed without
requiring encroachment in hazardous or difficult spaces.
When selecting aerial conduit, it is important to consider the environment
where it will be placed. Constant direct exposure to UV radiation and
ozone deteriorates the life of plastics such as polyethylene, the material
used to manufacture conduit. Colored conduit has a lower tolerance to UV
exposure and will have a shorter life. It is strongly recommended for aerial
applications that black conduit be used. Black has a much higher tolerance
to UV exposure and will provide a much longer life of usefulness than other
conduits.
