They are used in modern fire and security and alarm systems, access control systems and other control and monitoring systems, telephone exchanges and switchboards, as well as for signal transmission in the telecommunications sector. They are used for stationary laying inside buildings and structures, in dry and damp rooms. Laying on external walls is allowed only under plaster, and indoors – both over plaster and under it.<\/p>\n The cables are not intended for high-voltage power installations, power supply of electrical equipment and use in the ground.<\/p>\n A protective shield in the construction of cables marked (St) reflects interference from adjacent wires, and also protects the transmitted signal from electromagnetic fields emitted by wiring, electric motors and other similar devices. Due to this, high quality of information transmission is maintained and losses are minimized. The conductor is made of copper. The number of conductors varies from 1 to 32 pairs with a diameter of 0.6 to 1.38 mm. The conductors are stranded in pairs and covered with PVC insulation. The overall shield is predominantly made of polymer coated with aluminum and provides protection of the cable from electromagnetic waves and external high-frequency interference, and the pair twisting of the cable conductors prevents mutual and cross-talk. The outer sheath of the cables is made of PVC-plastic or non-flammable, self-extinguishing and hardly flammable PVC-plastic.<\/p>\n Cables are resistant to flame propagation in case of a single laying, and cables marked with the letter U (J-YYU-PF and J-Y(St)YU-PF) in a PVC sheath of low flammability are characterized by increased resistance to flame propagation also when laid in bundles. Non-combustible cables under the influence of fire do not emit corrosive combustion products and thick smoke that are dangerous to humans, and are used in facilities with increased requirements for fire safety (in places of large gathering of people or material and cultural values).<\/p>\n\u00a0<\/strong>Applicability scope<\/strong><\/h5>\n
