KVVGNG (A) -FRLS, KVVGENG (A) –FRLS

Applying area and purpose

Cables are designed for fixed connection to electrical appliances, devices, terminal assemblies of electrical switchgears for rated alternating voltage up to 660 at a frequency of up to 100 Hz or direct voltage up to 1000 V, for laying in rooms, channels, tunnels, in aggressive environments, in the absence of mechanical stress on the cable. Laying in the ground (trenches) is allowed while protecting the cables at the points of exit to the surface.

Shielded cables are used when it is necessary to protect electrical circuits from the influence of external electric fields.

Cables are manufactured for general industrial use and for use at nuclear power plants (AC) outside the containment zone in AC class 2 systems according to the classification OPB 88/97 (PNAE G-01-011).

Fire hazard class according to NATIONAL QUALITY STANDARD 31565 p1b.1.2.2.2.

Technical data

Conductive core

Copper single-wire, class 1

according to NATIONAL QUALITY STANDARD 22483, section from 0.75 to 6 mm2.

Thermal barrier according to thermal conductivity

A winding of two mica tapes.

Insulation

PVC compound low fire hazard.

Twisting

The number of cores is from 4 to 61. The insulated cores are twisted into a core, the cores are color or digitally labeled so that each core can be identified during installation. The color marking is solid or in the form of longitudinal stripes with a width of at least 1 mm.
