Main design elements 1. One round conductive core: - Material: Aluminum (AI) - Number of conductive cores: 4; 5; 7; 10; 14; 19; 27; 37; 52; 61; -2.5 mm2 -Number of conductors: 4; 5; 7; 10; 14; - (4-10) mm2 Copper (Cu) -Number of conductors: 4; 5; 7; 10; 14; 19; 27; 37; 52; 61; -2.5 mm2 -number of conductors 4; 5; 7; 10; 14; - (4-10) mm2
*. Thermal barrier: -for cables with the “FRLS” index, two overlapping mica-containing tapes are wound over the conductive core.
2. Insulation: -Made of low fire hazard (B) polyvinyl chloride plastic; -Made of cross-linked polyethylene (PV).
3. Internal filling (inner sheath): -Made of low fire hazard PVC plastic
*. Screen: -for KVVGEng(A)-LS, KPvVGEng(A)-LS, KVVGEng(A)-FRLS cables made of two copper tapes or aluminum foil with overlap, copper wire must be laid along the aluminum foil.
4. Armor: -for (A)KVBBShvng(A)-LS, (A)KVBShvng(A)-LS, (A)KPvBBShvng(A)-FRLS, (A)KPvBShvng(A)-LS cables - armor made of 2 galvanized steel tapes; -for cables (A)KVKShvng(A)-LS, (A)KPvKShvng(A)-LS - made of galvanized steel wires.
5. Sheath: -made of polyvinyl chloride plastic with reduced fire hazard.
Cable brand KVVGng(A)-LS, KVVGng-LS, AKVVGng-LS, KPVVGng(A)-LS, KBBГнr(A)-FRLS control cable or fire-resistant control cable with a thermal barrier made of mica-containing tape on the conductive core, with insulation made of low fire hazard polyvinyl chloride plastic (B) or cross-linked polyethylene (PV) and a sheath made of low fire hazard polyvinyl chloride plastic
Cable type KVVGeng(A)-LS, KVVGeng-LS, AKVVGEng-LS, KPVGEng(A)-LS, KBBGEngr(A)-FRLS With a common screen under the sheath
Main area of application The cables are designed for installation in rooms, ducts, tunnels, in aggressive environments without mechanical impact on the cable. Installation in the ground (trenches) is permitted provided that the cables are protected at the points where they come to the surface. For group installation of cable lines in cable structures and rooms of internal (closed) electrical installations; for electrical wiring in residential and public buildings. Cables with the “FRLS” index are designed for electrical wiring of fire safety systems (fire alarm circuits, fire extinguishing pump power supply, emergency exit and evacuation route lighting, evacuation elevators), for electrical wiring in hospital operating rooms, emergency power supply circuits, and equipment power supply circuits (current collectors) that operate during a fire. The cables do not spread combustion when laid in bundles. KBBГЭнr-FR cables
