Applying area and purpose
Cables are designed for fixed connection to electrical devices, apparatuses, terminal assemblies of electrical switchgears for a rated alternating voltage of 660 at a frequency of up to 100 Hz or a constant voltage of up to 1000 V.
Cables are used for group laying of cable lines for power and control circuits. Cables are intended for use in large thermal power plants, petrochemical facilities, in the subway, in buildings and structures with a large stay of people, concert halls and indoor stadiums, theaters, airports, train stations, and in rooms equipped with a computer and microprocessor technology and other facilities that are subject to increased fire safety requirements. Fire-resistant cables remain operational under conditions of flame exposure for 180 minutes.
Shielded cables are used when it is necessary to protect electrical circuits from the influence of external electric fields.
Armored cables are used when there is a risk of mechanical damage during operation, if the cable is not subjected to significant tensile forces.
Fire hazard class in accordance with NATIONAL QUALITY STANDARD 31565 cables of the execution "ng (a) -frhf" - p1b.1.1.2.1.
