APPLICATION

Armoured mounting cables are designed for the fixed connection of electric devices operating at AC nominal voltage up to 500V frequency to 400Hz or DC voltage up to 750V.
MKEKbSHv — shielded tinned copper multicore cable with PVC insulation and sheath with steel wire armouring in PVC protective hose;
MKKbSHv — tinned copper multicore cable with PVC insulation and sheath with steel wire armouring in PVC protective hose.

DESIGN

CONDUCTOR — tined copper multiwire;
INSULATION —PVC; Insulated cores have identification colouring.
STRAND — insulated cores are twisted. Each layer has two identification conductors.
ZONAL INSULATION — PVC.
SHIELD — copper wires of 0,2 mm diameter. Shield density is not less than 60%.
ARMOURING — tined steel wires of 0,3 mm diameter. Armouring density is not less than 65%;
PROTECTIVE HOSE — PVC; over the armouring of cable.
NUMBER OF CONDUCTORS — 2,3,5,7,10,14,19.
CONDUCTOR CROSS-SECTION, mm² — 0,35; 0,5; 0,75; 1.

TECHNICAL DATA

Electric resistance of conductor insulation per 1 km at 20ºС should not be less than 10 МОhm.
Cables resist to bending, cyclic heating in a salt bath.
Permissible operational temperatures is from -40˚С to +60˚С.
The maximum operational temperature of conductors should not exceed 60°С.
Cables resist to relative humidity up to 93% at the ambient temperature up to +40°С.
Minimal bending radius of cables at installation should not be less than 15 maximal diameters of cable.
КMaximum permissible operational temperature of conductor is +60°С.
Cables do not extend combustion at a single laying.
The delivery length should not be less than 50 m, 3m and more cable pieces are possible to deliver but not more than 10% of total length of batch.

Average service life of a cable is not less than 5 years;
