To maintain the continuity of Cable specially for long length, the jointing systems came into existence.  The jointing systems can be Straight Through for XLPE to XLPE or PILC to PILC Cable and can be Transition Joint type for connection of XLPE to PILC Cable.  The voltage grade is from 1.1 kV onwards.  The jointing system works properly in underground cable even with water stagnation in the ground.

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.
