Emergency wire cutter for LV overhead conductors

Emergency wire cutter for LV overhead conductors


Category:

The device is used to cut low voltage overhead conductors in emergency situations and contains the following components:
a. Wire cutter (1 piece);
b. Telescopic insulating stick (1 piece).

The wire cutter is designed to easily grip the conductor that must be cut from the ground. The cutting parts are made of alloy steel with high mechanical strength. The maximum diameter of the LV conductor (cooper or aluminum / bare or insulated) that can be cut is 25 mm. In order to reduce the cutting force, the lever of the mobile cutting part is operated from the ground by means of a rope, passed through a system of two pulleys. The coupling system of the wire cutter with the telescopic insulating stick is sunrise type, allowing the cutter to be positioned in an angle of 0°, 30°, 60° and 90° toward the stick`s axis.

We recommend to use the wire cutter for cutting single-phase conductors (single core or multicore). In this case, even if the conductor is live, no electric arc occurs. If the wire cutter is used to cut live electrical cables with multiple conductors, an electric arc will occur, causing partial or total damage of the cutting parts (depending on the current passing through the cut conductors, as you can see in the movie below). The wire cutter is provided with replaceable cutting parts. We strongly recommend wearing appropriate personal protective equipment (helmet with electric arc visor, protective suits against arc flash, etc.).

The telescopic insulating stick consists of 5 modules made of insulating tubes, meeting the requirements of SR EN 61235: 1999. To firmly lock the modules in an extended position, they are provided with blocking buttons of square shape. The upper area of the sections are covered with transparent elastic sleeves, in order to increase the lifetime of the stick.

The insulating stick is provided with a hinged sole. It is not recommended to operate the scissors and handle the stick with the stick lifted from the ground. The insulating stick is provided with a metallic coupling system that allows a secure fixing of the wire cutter.

Both components are delivered in waterproof bags.
