Flexible armoured power cable
KGVKbG, KGVKbSHv under Belarus quality requirements 500017371.056-2009
Flexible armoured power cables are designed for connecting of mobile machines, mechanisms and equipment to electric mains for AC nominal voltage 660V frequency up to 400 Hz or DC nominal voltage 1000V.
KGVKbG — PVC insulated multicore flexible cable with tined steel wire armouring;
KGVKbSHv — PVC insulated multicore flexible cable with tined steel wire armouring in PVC protective hose.
CONDUCTOR — copper multiwire.
INSULATION — PVC; Insulated cores have identification colouring.
STRAND — insulated cores (2, 3, 4) are twisted. In five-core cables cores are twisted around PVC string.
ZONAL INSULATION — PVC.
ARMOURING — tined steel wires of 0,3 mm diameter. Armouring density is not less than 60%;
PROTECTIVE HOSE — PVC;
NUMBER OF CONDUCTORS — 2; 3; 4; 5.
CONDUCTOR CROSS-SECTION, mm² — 0,75; 1,0; 1,5; 2,5; 4,0; 6,0.
Permissible operational temperatures for KGVKbSHv is from -40˚С to +60˚С; for KGVKbG is from +1˚С to +60˚С.
Maximum permissible temperature of conductor is +70°С.
Cables resist to bending, cyclic heating in a salt bath.
Cables resist to air humidity.
Minimal bending radius of cables at installation should not be less than 15 maximal diameters of cable.
Cables do not extend combustion at a single laying.
The delivery length should not be less than 50 m, 20m and more cable pieces are possible to deliver but not more than 20% of total length of batch.
Average service life of a cable is 5 years.
