Purpose of the development: The device is designed for cutting stranded wires and cables under voltage. It was created for the purpose of emergency blackout during a fire in residential buildings and structures, the input of which is made by a self-supporting wire of the SIP brand.

Recommended application field: Shut off objects before firefighting during firefighting operations.

Technical characteristic: - cutting wires under voltage up to 220 V; - it is possible to cut the wires at a distance of up to 1200 mm; - cutting disc - 180 mm; - wire diameter - 2-4 sq.cm; - DC motor - 3000 rpm; - power supply - 12 V.

Advantages over analogues: Reduced time to prepare the device for use, mobility and efficiency in use; safe and trouble-free cross-section of live wires and cables, which eliminates the possibility of damage to a person from dangerous factors of short circuit and the use of a powder charge; elimination of the possibility of emergency operation of the electrical network; minimization of attracting the number of personnel of fire rescue units to de-energize the facility.

The development stage readiness: Pre-production model is made

Description of the development:
()
One of the stages of the operational actions of the fire and rescue units during fire fighting is to deenergize the facility. To carry out this work, rescuers are equipped with a special dielectric tool - dielectric scissors. Since the main condition for the use of scissors is the cutting of wires under voltage up to 220 V, they can not be used in modern conditions. In 2006, the rules for the arrangement of electrical equipment were amended. One of the innovations was the requirement that the lines of electrical networks that are being reconstructed or built in the residential sector must be made by self-supporting insulated wire (SIP). Ukrainian scientists have developed a means of de-energizing buildings, the input of which is made using a self-supporting insulated wire. The device comprises an engine, a rod with a shaft inside, which is connected at one end to the engine, and at the other end, through a gearbox on which the device for fixing the wire is fixed, with a cutting element, which is used as a cutting wheel made of dielectric material. The rod is separated from the engine and gear by dielectric inserts, the cutting wheel may have a protective casing. Using extension rods allows cutting wires directly from the ground without additional equipment (stairs, elevators, etc.).
