Abstract

In this paper we present development process and results of some cases for underground pad transformer and switchgear. Some characteristic factors was considered and tested to improve the functions of the case, such as natural convection of cooling air between the internal and external cases, properties of material that used as external panel etc. Proposed designs and functional characteristics will be adapted to making the cases of underground facilities after the elaborated tests. The results obtained from this study will improve the scenery of a street.
