Cables are designed for fixed connection to electrical devices, apparatuses, assemblies of clamps of electrical switchgears with rated alternating voltage up to 660 V of 100 Hz frequency or constant voltage up to 1000 V. They are used for laying in rooms, channels, tunnels in the conditions of an aggressive environment, in the absence of mechanical influences on the cable.
Cable with copper single-wire cores which are insulated with polyvinyl chloride plastic, are twisted together in a common polyvinyl chloride shell. The outer sheath of the cable repeats the shape of twisted strands.
Cables should be operated in a stationary state at an ambient temperature of minus 50 ° С to plus 50 ° С, relative humidity of air up to 98% at a temperature of up to 35 ° С.
Cables are designed for electrical installations for stationary laying in lighting and power networks as well as for the installation of electrical equipment, machines, mechanisms and machines for a rated voltage of up to 450V (for networks up to 450 ÷ 750V) with a frequency of up to 400Hz or a constant voltage of up to 1000V.
The conductor is a copper wire. Each vein consists of copper conductors, the core class has to be at least 3.
Insulation: polyvinyl chloride plastic. The color of the insulation is different; the color is solid or is made by applying two longitudinal strips on an insulation of natural color, located diametrically. The wire used for grounding circuits has a yellow-green insulation.
The construction length of the wires is not less than 100 m, short-lengths of at least 20 m in length of 10%.
Operating temperature range: from minus 50 ° С to plus 70 ° С.
