Automatic splice full tension aluminum


Automatic splice connector are also named mid span joint,splice connector makes fast and dependable overhead automatic splice connector that take a bite out of installation time.automatic splice are used for splicing or repairing conductor of overhead transmission and distribution lines.Mid span joint provide a reliable,economical,and easy to install splicing method for overhead transmission and distribution lines.The conductor simply slips into the color-coded, funnel-shaped end piece and automatically enters the pilot cup with a gentle push. The pilot cup guides the conductor past the unique serrated jaws and into the center of the connector. When the conductor meets the center stop, the pull-back locks it into position as the jaws firmly clamp down. The more pull, the more bite, which provides an instant, positive and automatic connection.The automatic splice can be used for ACSR, AAAC and AAC Conductors.


Shell – High Strength Aluminum Alloy
Jaws – Aluminum Alloy

Color-coded, funnel-shaped end pieces provide instant visual identification of maximum conductor size and swiftly guide conductor into position for insertion.


1.The tapered shell design ensures high strength adhesion between it and the conductor,it can make the conductor easier to slip in.
2.The metal clip is embedded inside the conductor to enhanced the conductivity.
3.The metal clip can conduct current to the body of automatic splice with higher conductivity
4.The teeth of the metal clip can penetrate the residual oxide layer on the surface of the conductor
5.Large area of contact points help heat dissipation
6.The meshing metal clip maintains good electrical conductivity under various conditions of tension changes
No special tools are required for installation, which is convenient for live working installation, simplifies the installation steps, and greatly improves the safety of the operation
7.Color-coded tape can identify the smallest conductor size of a wide range of connectors-further eliminating errors and speeding up installation!

How to select automatic splice

For example,your conductor size is ACSR 1/0,you can choose the item code GL 406,the automatic splice color code is Yellow.You also can choose the GL 4076,it can used for minimum conductor size 1/0,maximum conductor size 2/0.
