HIGH-VOLTAGE OUTDOOR DISTRIBUTION INSTALLATION

摘要

A high-voltage outdoor distribution installation primarily of three-phase current and of a low level design, comprises electric equipment having poles which are electrically interconnected and mounted on cross-arms of supports having legs secured to foundations, at least two poles of the electric equipment being arranged on each support. The foundations are in the form of unburied beams on the ground surface. At least two adjacent supports carrying the electrical equipment are combined into three-phase modules whose frames are formed by said supports and foundation beams coupling the legs of said supports in the direction normal to the direction of the crossarms.
