Line clamps

Clamps that are attached to de-energized parts of the electrical system to create a secure connection to the ground.  They are usually connected to ground clamps via cables (and depending on the configuration, via junction blocks).

Line Clamps are secured to overhead lines using two types of systems:

Screw-type spindles:  With this system, the line clamp is tightened by turning a threaded spindle.  Our spindles support a number of attachments and adapters, including bayonets, Pfisterer type bayonets, shotguns and fixed PVC or fibreglass handles.  Screw-type fastening systems reliably secure clamps to overhead lines.

Snap-on mechanisms:  These clamps have a spring-loaded mechanism which is triggered by hooking the top jaw over the overhead line.  These snap-on clamps enable the PED to be quickly secured to an overhead line.

All our line clamps are tested to IEC 61230.
