Wiring and installation cables according to TU 3551-023-76960731-2012

  • KUIN-Pu wires and KUIN-Ku cables comply with the new GOST 31947-2012 “Wires and cables for electrical installations with a rated voltage up to and including 450/750 V. General technical requirements,” which replaced GOST 6323-79 on January 1, 2014. As a result, wires of the PV1, PV2, PV3, PV4, PPV, APV, and APPV brands manufactured according to GOST 6323-79 can no longer be used in the Russian Federation.

Scope of application:

    • lighting networks;
    • installation of electrical equipment, machines, mechanisms, and machines with a rated AC voltage up to 450/750V at a frequency of up to 400Hz or DC voltage up to 1000V.

  • Cables and wires are designed for stationary installation both indoors and outdoors, including electrical wiring under plaster, in concrete, brickwork, voids of building structures, as well as openly along walls and ceilings, and in other structures, including those requiring increased flexibility.

    Cables and wires can be used in all classes of explosive zones (subject to the requirements of GOST IEC 60079-14).

    Fire-resistant cables and wires can be used in all electrical installations that are subject to fire resistance requirements in accordance with Federal Law No. 123 “Technical Regulations on Fire Safety Requirements” and GOST 31565-2012 “Cable Products. Fire Safety Requirements.”

Cable design

  • Cables have a round shape, while multi-core wires have a flat shape. Conductive cores are made of copper wire or tinned copper wire (“l”). Flexible wires and cables (“G”) have a class 5 conductor according to GOST 22483. The conductor class is specified in Table 1.

    The number and nominal cross-section of conductive cores are given in Table 2. Multi-core wires and cables have all cores of the same cross-section. In 3-core, 4-core, and 5-core cables, the grounding core may have a smaller cross-section (see Table 3). Upon special request, cables can be manufactured with a combined cross-section of conductive cores. The color coding of insulated cores and the sheath is specified in Table 4 and Table 5. The green-yellow color is used to designate the grounding core (“PE”), while the blue color is used for the neutral core (“N”).

    Fire-resistant wires and cables (“FR”) have a wrapping of two mica-containing tapes under the core insulation, which is the most reliable method of ensuring fire resistance.

    Wires and cables may have shielding:

    • “E” — aluminum-polymer film with a tinned copper conductor,
    • “Em” — copper wire braid,
    • “El” — tinned copper wire braid.

    The sheath of multi-core wires and cables fills the gaps between the cores, giving the wire a flat shape and the cable a round shape. Additionally, separate extruded filling may be applied under the sheath. Wires and cables may have a water-blocking element (“v”) that prevents the free spread of water under the sheath. Single-core wires can be manufactured without a sheath, in which case the sheath material does not need to be specified in the wire designation. Wires and cables may have armor made of galvanized steel wires (“K”), with an outer sheath applied over the armor. The insulation of cores and the sheath can be made of PVC plastic (“B”), halogen-free polymer composition (“P”), or thermoplastic elastomer (“T”). Table 6 and Table 7 provide details on insulation and sheath materials, as well as their corresponding fire safety classifications.
