Hook stick Operation The Type AR switch can be operated by a hook stick operation. This option eliminates control pipe sections down the pole and their attendant adjustment during installation and maintenance.
Extra Pipe The extra pipe section includes guide, coupling, and all hardware for attachment.
Extension Links When deadending to the AR switch, exten- sion links must be used to give needed clearance. The end clevis has a slotted hole for inserting the machine bolt with- out having to remove the extension bar. The extension links supplied are 14 inches long,
Surge Arrester Brackets Three brackets can be supplied for mounting six surge arresters (utility supplied) for over- voltage protection.
Sensor Brackets Extension Brackets can be supplied, or added to the AR Switch, to allow for the additon of line volt- age/current sensors.
Crossarm Braces Crossarm braces may be specified as an option.
