Abstract
A compartment module for a metal-enclosed, modular medium-voltage distribution system has an essentially box-type construction and includes a first set of mutually opposite completely closed walls, a second set of mutually opposite walls having identical large openings bounded by a narrow flange, and a third set of mutually opposite walls having small openings bounded by a wide flange. When assembled, a number of the modules can be arranged to face one another with similar walls and the remaining openings closed off by a cover. The modules can be mechanically coupled to each other by bolt joints or clamp joints in order to obtain a mechanical and electromagnetic seal. A method of manufacturing a module from sheet metal, and a method of manufacturing a medium-voltage distribution system from standard modules includes using isolators and busbar systems.
