The device is used for the ground cutting of low voltage overhead electrical derivations in emergency situations.
The cutter includes the following components:
a. cutting scissors actuated by a lever and pulley system (1 piece)
b. telescopic insulating stick (1 piece)
The cutting scissors are designed to facilitate the cutting of the derivation from the ground. The cutting knives are made of high-alloy steel with great mechanical strength. In order to reduce the cutting force, the operating lever of the mobile knife is actuated from the ground with a rope, passed through a system of 2 pulleys.
The coupling system of the cutting scissors with the telescopic insulating stick is of the hinged type, allowing the scissors to be positioned in a plan that includes the stick axis under a 0°, 30°, 60° and 90° angle.
The telescopic insulating stick includes 5 modules made of insulating tubes, according to the requirements of SR EN 61235:1999.
For the firm locking of modules in extended position, these are provided with square lock buttons, and the upper areas of the sections (provided with sockets for the lock buttons) are covered with elastic transparent sleeves, in order to increase the operating period of the stick.
The stick is provided with hinged sole in order to be supported on the ground during works and a metallic coupling system that allows an appropriate fixing of the cutting scissors.
It is not recommended to operate the scissors and handle the stick without supporting it on the ground.
Both the cutting scissors and the insulating stick are delivered in waterproof bags.
