Self Contained Fluid Filled (SCFF)/Low Pressure Oil Filled (LPOF)

An approximately 800 m section of two 115 kV LPOF circuits was relocated in a major North American city to accommodate a new streetcar maintenance facility. A new concrete encased ductbank with three different cross section arrangements was installed to house the existing and future underground utilities. New custom manholes and joint bay were also installed along the right-of-way. New pre-pressurized oil reservoirs were installed including stop and straight joints. Expulsion and impregnation tests were performed revealing a successful cable installation. Ground resistance measurements at the manhole locations indicated a low resistivity value. The abandoned power cable was removed and disposed.
