Measures for Improving Joints and Connection
1. Spacing of poles: The spacing between poles (for overhead lines) is also an important requirement. Long spans will result in sagging of conductors with all its associated problems and should be avoided.
2. Connections between overhead and underground system: The end terminations of the cables where the supply is tapped from the lines, although properly finished using good end termination kits, get deteriorated over time. This is due to continuous exposure to the different weather conditions in different seasons. The entry of water/ moisture into the cable damages the insulation of the cable, leading to cable faults and should be prevented.
