KUIN-SP cables fully comply with Federal Law No. 123 “Technical Regulations on Fire Safety Requirements,” GOST R 53315-2009 “Cable Products. Fire Safety Requirements,” and fire protection system codes SP 5.13130.2009 and SP 6.13130.2009. The cables have the highest fire resistance rating, PO1, and maintain operability in fire conditions for at least 180 minutes.
The cables fully comply with the technical regulations of the Customs Union TR CU 012/2011 “On the Safety of Equipment for Use in Explosive Atmospheres” and GOST R IEC 60079-14-2008 “Explosive Atmospheres. Part 14. Design, Selection, and Installation of Electrical Installations,” making them suitable for use in all classes of explosive zones (except for lightweight version “O” cables).
Fire-resistant cables are designed for single and group stationary installation in modern systems as:
The cables are designed for indoor and outdoor use at facilities with increased fire safety requirements:
The primary areas of application for the cables, considering their design type and fire hazard class according to GOST R 53315-2009, are specified in Table 4.
Conductive cores can be either single-wire or multi-wire (“mj”) and are made of tinned (“l”) or untinned copper wire. The class of conductive cores according to GOST 22483 is specified in Table 2. High-flexibility cables (“G”) have a Class 5 core. The number of pairs and the nominal cross-section of the conductive cores are provided in Table 2. The color scheme for insulated cores is listed in Table 3. Conductive cores are twisted into pairs to reduce the impact of electromagnetic interference.
Fire-resistant cables marked with the material designation “R” have insulation made of silicone rubber, which forms a solid ceramic insulation layer around the conductive core in the event of a fire. In all other cables, fire resistance is achieved using mica-containing tapes applied to the core before insulation is added. The use of mica-containing tapes ensures maximum resistance to mechanical impacts during a fire.
Cables may have an individual screen for each pair and/or a common screen for all pairs. Screens can be made in the form of a copper wire braid (“Em”), a tinned copper wire braid (“El”), or an aluminum foil-laminated film (Alumoflex) with a tinned copper drain wire (“E”). Individual screens can be insulated from each other and may also be manufactured as combined screens, incorporating both Alumoflex and a copper braid.
The cables have a round shape and a bedding layer, obtained through extrusion, that prevents the free spread of gases under the sheath. Cables in the lightweight version (“O”) do not have a bedding layer, which makes them unsuitable for use in explosive zones.
Cables with a twisted-pair core may include a water-blocking element (“v”) to prevent the free spread of water under the sheath. They can also be armored with galvanized steel wires (“K”) or galvanized steel tapes (“B”). An outer sheath is applied over the armor.
Table 1 provides information on insulation and sheath materials, as well as their corresponding fire safety characteristics.
Upon special request, cables can be manufactured with a combined cross-section of conductive cores.
The service life of cables made from thermoplastic elastomer (“T”) is at least 25 years, while all other cables have a service life of at least 30 years.
