Indication Examples

The indication of plastic insulated control cable consists of type, number

of cores, nominal cross-sectional area of conductor. When the same type

products are made by difference class of conductors, the more flexible one

is indicated with (B) following the specification.

For examples:

1.PVC insulated, PVC sheathed control cable, 16 cores, nominal .(cross-sectional area is 2.5 mm2, is indicated as:)

KVV 16x2.5 for the harder one, or KVV 16x2.5 (B) for the more flexible one.

2.XLPE insulated, PVC sheathed tow-ply galvanized steel tapes armored control cable, flame retardant, 12 cores, nominal cross-

sectional area is 4mm2, is indicated as:

Z-KYJV22 12x4

Using Features & Main Technical Performances

①Rated voltage (U,/U): 450/750V.

②The maximum long-term operating temperature of conductor:

PVC insulated cable: 70C,

XLPE insulated cable: 90 C.

③The minimum ambient temperature in laying is:

0C for low-smoke or halogen-free, PVC or polyolefin sheathed, flame

retardant cable.(It should be preheated if the ambient temperature in laying

is below the minimum temperature).

④The permitted bending radius of the cable:

No less than 12 times of the overall diameter of the cable for witch has

armor or copper tape wrapped shielded.

No less than 6 times of the overall diameter of the cable for the others.

⑤)Flame characteristics:

Flame-retardant and fire resistance cable are manufactured based on the

GB/T standard 19666-2005.
