High load distribution network in the 80's

High duty, compact equipment having no negative environmental effects when used in high power distribution networks, was developed. Digital computer programs allowed for optimization of the design and simulation of the operating conditions of system components. A computer model allowed for testing and choosing the optimal medium voltage network and the possible extensions of the low tension network. Materials were elaborated and tested in order to guarantees a reliable long-term behavior of the components. This led to the development of a space saving insulator traverse and helped to solve stressing problems of VPE-cables also with internal forced water cooling. With the development and production of a subterranean muffled transformer for powerful low voltage consumers, all the necessary system components for a densely populated area are available.
