|
КГВВ |
flexible control cable in PVC insulation, with PVC sheath |
|
КГВВнг(А) |
flexible control cable in PVC insulation, with fire-resistant PVC sheath |
|
КГВВнг(А)-LS |
flexible control cable in PVC insulation,in flame-retardant PVCcompound sheath with low gas and fume emission |
|
КГВЭВ |
flexible control cable in PVC insulation, with PVC sheath, shielded |
|
КГВЭВнг(А) |
flexible control cable in PVC insulation, with fire-resistant PVC sheath, shielded |
|
КГВЭВнг(А)-LS |
flexible control cable in PVC insulation, in flame-retardant PVCcompound sheath with low gas and fume emission, shielded |
When insulated conductors are parallel laid, index "П" is added to cable model (example: "КГВЭВнг(А)-П")
When space between conductors is filled by laying of sheath, index "з" is added to cable model (example: "КГВВзнг(А)").
Whenconductorsare numerically tagged, index "ц" is added after conductor area index (example: "КГВВнг(А) 3*0,75 ц").
ARRANGEMENT
CONDUCTOR:copper, stranded.
STRAND:insulated conductors of two- or three-core flat cables with "П" index are parallel laid. Insulated conductors of other cables are stranded.
INSULATION: conductors are insulated with PVC compound; cables of нг(А)-LS modifications- flame-retardant PVC compound with low gas and fume emission. For cables of ХЛ1 climatic modification - PVC compound shall be frost-resistant. Insulated conductors with up to five conductors inclusively have distinctive coloring. Coloring of outer insulation or strip painting with not more than 1 mm strip width is allowed.
Insulated cable conductors with more than five conductors in each lay-up have meter pair which differs in color between each conductor in pair and from other conductors of lay-up.
Cables having "ц" index are numerically tagged. Tagging is different in color from the color of conductor insulation. Interval between the numbers shall be not more than 35 mm.
BRAIDING:stranded cable conductors are winded with polyethylene terephthalate film.
It's allowed to manufacture unbraided cables provided that conductors are movable and easily separated from sheath while cable stripping.
SHIELDING:Braided cables shall be shielded with copper or tinned copper wire braiding of not more than 0.3 mm diameter and not less than 70% coverage. When tinned copper wire is used, index "л" is added to the model name.
SHEATH:over unshielded cables braiding, the PVC compound sheath shall be laid; for cables of нг(А) modification - fire resistant PVC compound sheath; for cables of нг(А)-LS modifications- flame-retardant PVC compound sheath with low gas and fume emission. For cables of ХЛ1 climatic modification - PVC compound shall be frost-resistant.
Sheath color is negotiable. By default the sheath can be of any color.
Manufacturing of cables of Т1 modification with white or natural-colored sheath is not allowed.
