Insulating the bus bar and switchgear joints is a very unwieldy and herculent job owing to a very complex and varied profile of the joints in the layouts that are of very customized nature. Because of this majority of the joints are left open without insulation. This in turn results in short circuits, breakdowns and in best cases the interruptions. Also this is an aspect of human safety that can never be ignored. In developed countries these are used even in areas that are never reached by humans just to save the wild life of birds. In India one hardly comes across any insulation of these live high voltage joints which frequently lead to loss of lives.
