Disconnectors can be classified into various types based upon their constructional features and mounting arrangement. The major types of disconnectors are:
Centre-break disconnectors
Double-break disconnectors
Pantograph disconnectors
Horizontal break knee disconnectors
These are selected based upon the sub-station layout, clearances available and space constrains.
