INSTALLATION

The switch can be mounted on timber poles with a 
keyhole arrangement or concrete poles using banded 

straps. The following types of installations are supported:

•   Mounted to the pole above the powerline

•  Mounted to the pole below the powerline

Prior to mounting on the pole, the switch must be fitted 
to the mounting bracket and all surge arrestors and 
cable tails fitted.  

The hanging bracket can be mounted above or below 
the cross arm depending on the customer’s preferred 
installation location. 

The switch is completely symmetrical so it can be 
mounted with the hook stick operator facing toward the 
pole or away from the pole.  

The switch assembly can be fixed to the pole via a 
crane, pole mounted hoist or EPV. Lifting points are 
provided to allow for lifting of the assembled switch.  

The switch is to remain within 15 degrees of horizontal 

whilst lifting.  An M12 stud on the switch is provided for 

an earth connection. A minimum thickness of 35mm

copper conductor must be used.  

Standard hand tools will be all that is required to 
complete the installation, namely ring, adjustable
