To maintain the continuity of the underground cables the need for the reliable jointing systems came into existence. Cable terminations and joints have always been very critical part in the whole distribution system involving underground cables and have often been the causes of failure in the distribution system as well. There has always been a need to improve the reliability of the underground distribution system through newer materials that can withstand stringent operating conditions and installed without a room for errors.

There are wide range of cable jointing systems available today, which can be classified by the way they are applied such as taped type, pre-moulded / push-on / slip-on type, cold application type and heat shrinkable type. The selection criterion for an appropriate type of cable jointing system by the user should be dependent on the site conditions, operating parameters, voltage applications and cable types.
