Installation cables КУИН-Ку
manufactured acc. to ТУ 3551-023-76960731-2012

КУИН-Ку cables conform fully to the new GOST R 53768-2010 "Wires and cables for electrical equipment of rated voltage up to and including 450/750 V. General specifications" which has replaced the GOST 6323-79 on 01.01.2011 wherefore wires ПВ1, ПВ2, ПВ3, ПВ4, ППВ, АПВ and АППВ under GOST 6323-79 can no longer be used on the territory of the Russian Federation.

Area of application

  • lighting mains;
  • electric equipment installation, machines mounting, machinery and machine tools of rated voltage up to and including 450/750 V AC with frequency up to 400 Hz or steady voltage up to 1000 V DC mounting.

Cables and wires are designed for fixed cabling indoor and outdoor premises, for wires installation under plaster, into concrete, brick laying, building constructions air void as well as for surface on-walls and on-ceiling wiring and wiring in other constructions some of which require extra-flexibility.

Cables and wires can be used in all classes and all explosive hazardous danger areas (under GOST R IEC 60079-14-2008).

Fire-resistant cables and wires can be used in all electric plants requiring fire resistance under FL №123 "Technical regulations on fire safety requirements" and GOST R 53315-2009 "Cable products. Requirements of fire safety". Primary wires and cables application fields with a glance to their modification and fire safety class are listed in table 5.

Cable design

Cables have circular shape . Electric conductors are made of copper tin-coated "л" and untinned wire. Extra-flexible cables "Г" have a 5 class conductor under GOST 22483. Electrical conductors’ classes are specified in table 1.

Main conductors, cable earthing conductor and cable neutral conductor are of equal cross-sectional area. 3-, 4- and 5-conductor cables can have earthing conductor cross-sectional area as of 16mm² with main conductors as of 25 and 35mm², and earthing conductor cross-sectional areaas of 25m2 with main conductors as of 50mm². A number and nominal cross-sectional areas of electrical conductors are listed in table 2. Colouring of insulated conductors is specified in table 3. Yellow green colour is used for earthing conductor with "PE" sign, and blue colour is used for neutral conductor with "N" sign.

Fire resistant cables "FR" have got mica tape wound under conductor insulation - this is the safest fire protection method at the moment.

Cables may have shield made from copper wire - "Эм" index, tinned copper wire - "Эл" index, or aluminium foil film with copper tinned conductor - "Э" index.

The jacket of multicore cables fills gaps between conductors giving round shape to it.. Cables may have a water swelling element "в" preventing unguided propagation of moisture under a cable jacket. Cables may have armour made of zinc-coated steel wires "К". Over armour there is a cable jacket overlaid. Conductors' insulation and jacket can be made of PVC compound "В", halogen free polymer compound "П" or thermoelastoplastic "Т". Insulation and jacket materials are listed in table 4 as well as corresponding fire safety indexes. Cables can be produced with combined conductor cross-section under customised order.
