Underground Conduit

SKU: TDUGC00CENDuration: 60 Minutes

The purpose of this course is to teach how to pull cable in manholes and how oil-filled metal conduit is monitored and maintained. The course describes typical cable-pulling equipment and demonstrates how it is used to pull cable in manholes. Oil-filled metal conduit is described, and the principles of corrosion monitoring are explained. An approach to repair of a leaking oil-filled metal conduit is also presented. At the conclusion of this course, participants should be able to describe and demonstrate how cable-pulling equipment is used to pull cable in manholes. They should also understand the purpose of oil-filled metal conduit, and they should be able to explain how corrosion-monitoring equipment works and how to repair leaking oil-filled metal conduit.
