CONNECTORS AND SPLICERS ON TRANSMISSION AND DISTRIBUTION LINES

Automatic Splicer
Connectors and splices are natural occurrence in transmission and distribution system. They are part and parcel of the system. They occur as a connection in either of the following:

1.      Dead ends
2.      Laterals
3.      Terminals or termination points
4.      Broken conductors due to breakage

Bail Clamp
Connectors and splices are often weak links in the overhead system, either due to hostile environment, bad design, or poor installation. In most cases utilities have had problems with connectors, especially with higher loadings.
Compression Connectors
 Most primary connectors use compression to join conductors. Compression splices join two conductors together by inserting them in each end of the sleeve, and a compression tool is used to tighten the sleeve around the conductors.
Hotline Clamp
 For conductors under tension, automatic splices are also available. Connection through automatic splicer are done by inserting the conductors in each end, and serrated clamps within the splice grip into the conductor; with higher tension, the wedging action holds tighter.
Full Tension Sleeve
 For tapping smaller conductor off a larger conductor, many options are available. Hot line clamps use a threaded bolt to hold the conductors together. Wedge connectors have a wedge driven between conductors held by a C-shaped body. Compression connectors use dies and compression tools to squeeze together two conductors and the connector.
