КControl cables are designed in industrial and wiring applications, in fixed installation for AC nominal voltage up to 660V and frequency 100 Hz or DC voltage up to 1000V. They are suitable for direct burial or for drawing into conduits in corrosive environment, if the mechanical stress involved is moderate. Cables should be protected at outcroppings
Cable with indexes “ng” (low flammability) and “ng-Ls” (low flammability, low gas and smoke emission) are used in cable constructions and premises to provide fire safety control of cable circuits and bunches.
CONDUCTOR — copper single-wire.
INSULATION — PVC. PVC with index “ng-LS” has low flammability and low gas- and smoke-emission.
STRAND — insulated conductors are twisted. In each layer of cable conductors there is a pair with individual colours.
SHEATH — PVC. PVC with index “ng” has low flammability; PVC with index “ng-LS” has low flammability and low gas- and smoke-emission.
NUMBER OF CONDUCTORS — 4, 5, 7, 10, 14, 19.
CROSS-SECTIONS, mm2 — 0,75; 1,0; 1,5; 2,5; 4,0; 6,0.
Range of operational temperatures is from +50˚С to -50˚С.
Cables resist to air humidity up to 98 % at an ambient temperature up to +35°C.
Permissible operational heating temperature of conductors is +70˚С.
Cables with an index “ng” and “ng-LS” do not extend combustion in bunches.
Cables resist to mounting bendings.
The delivery length should not be less than 150 meters, 20m and more cable pieces are possible to deliver but not more than 15% of total length of batch.
Average service life of cables is 15 years; in premises - 25 years.
