ABSTRACT
The generation, transmission, and distribution of power involve electrical facilities, apparatus, and components to carry the electrical energy from its generating site to where it is utilized. An important part of this power system is the medium-voltage cable system that is used exclusively to carry power from the main substation to secondary substations at load centers. Lowvoltage cable is used to distribute power from the load centers in conduits and ducts, even though other methods such as cable trays, direct burial for outdoor applications, and aerial cable are used. Electrical, mechanical, and environmental considerations are the main factors in selecting and applying cable systems for distribution and utilization of electrical power. The splices and terminations of medium-voltage cables or connections of different type of cables (such as aluminum and copper) require careful consideration and evaluation during installation, as well as throughout their service life. Correct installation and preventive maintenance of cable systems will assure continued electrical power service.
