Ultra-light Temporary Disconnect Line Tension Switch

The Firon line tension switch is ideal where temporary line sectionalising is required; it eliminates the need for pole mounted switches and reduces “pole clutter”. With a tested momentary of 40kA RMS (asymmetrical) and a current rating of 900 amps continuous, the switches are available in ratings from 15 through 69 kV.

Load Buster Hook

• Heavy duty galvanized steel Loadbuster™ hook is fastened to the jaw assembly with stainless steel fasteners for 15 to 34kV units.

Blade Opening Limits

• Two blade openings are available: 90 degrees and 180 degrees, the standard is a 180 degree opening, which is recommended for line switches. If a 90 degree blade opening is required, it should be requested at the time of order placement.

Large Pull Ring and Latch

• With the large tin plated, bronze pull ring located beyond the end of the switch blade, the switch in operation requires minimum effort to open or close (maximum leverage) and also provides the ultimate in operator control. A slight pull on the operating ring, transfers motion to the protected, tin plated spring-loaded latch, which initiates a pry out or ice breaking action to assist opening of the switch. The spring loaded latch provides the security of blade closure retention when exposed to short circuit currents and vibration.

Earth Spigot

• Each unit is supplied with a bronze earth spigot for temporary earth connection.
