FR + LS + armour
Fire-resistant armoured power cable with a mica fire barrier
VBShvng(A)-FRLS is the armoured version of VVGng(A)-FRLS for installation in the ground and under mechanical stress. Double steel tape armour and an outer sheath of low-fire-hazard PVC are added to the fire-resistant construction with a mica fire barrier. Used in underground fire protection system lines, metro tunnels, underground car parks and industrial facilities.
Sizes with actual technical specifications: outer diameter (with armour), weight, continuous current-carrying capacity in air. Full range of cross-sections: 2.5 — 240 mm².

VBShvng(A)-FRLS combines two important properties: fire resistance for fire safety systems and mechanical protection by armour for installation in the ground. The construction includes a fire barrier of mica-containing tapes over each conductor, armour of two galvanised steel tapes and an outer sheath of low-fire-hazard PVC compound.
Used where both fire resistance (90 minutes at 750°C) and protection against mechanical stress are required: routes between buildings, tunnels, underground car parks, industrial plants with a high fire load. Meets the requirements of Federal Law No. 123-FZ for critical loads.
Conductors
Stranded copper.
Fire barrier
Mica-containing tape over each conductor. Maintains circuit integrity under fire for ≥ 90 minutes.
Insulation
Low-fire-hazard PVC compound with colour coding.
Stranding and bedding under the armour
The insulated cores are stranded, with an extruded PVC bedding applied over them.
Armour
Two galvanised steel tapes applied helically with a gap of no more than 50% of the tape width.
Protective sheath
Low-fire-hazard PVC compound (LS), orange.
