KVBbSHv, KVBbSHvng, KVBbSHvngd<\/strong><\/span> are control armoured cables with copper conductors, PVC compound insulation, armor made of two galvanized steel bands and a PVC protective hose. The cables are used for fixed connection to electrical devices, apparatus, terminal block jumpers of electrical switchgears with a rated alternating voltage up to 660 V, a frequency up to 100 Hz or a constant voltage up to 1000 V.<\/p>\n

Applicability scope<\/strong><\/h5>\n

The main purpose of control cables is to connect individual sections of circuits located in different sections of devices or rooms.<\/p>\n

Armoured cable KVBbSHv is used for laying in rooms, channels, tunnels, in earth trenches, including in places exposed to leakage currents, provided the cable is not subjected to significant tension strain. Such cables can be laid directly in the ground since they are armoured. And also KVBbSHv can be used in adverse conditions of an aggressive environment.\u00a0 The laying outdoors is allowed provided the cable is protected from the mechanical damage and exposure to direct sunlight.<\/p>\n

The varieties of KVBbSHv of low flammability are used in places with a high probability of fire and the need to ensure the protection of people. They are marked with the letter indices \u00abng\u00bb and \u00abngd\u00bb. These cables are equipped with a sheath based on non-flammable PVC compound that does not spread combustion and significantly reduce the risk of damage to cable routes and equipment in the event of a fire.\u00a0<\/p>\n

KVBbSHvng is a flame-retardant cable, and KVBbSHvngd does not spread combustion and emits the minimum possible amount of smoke and toxic gases in a fire. KVBbSHvng and KVBbSHvngd could be laid in bundles.

Design<\/strong><\/h5>\n

KVBbSHv consists of a conductive single-wire copper conductor (class 1 DSTU EN 60228), with a cross section of 0.75 to 10 mm2<\/sup>. PVC conductors insulation has a distinctive color or digital marking. The conductors are stranded together, having an armor made of galvanized steel bands over the insulation. The upper band of the armor covers the gaps between the turns of the lower bands. A protective PVC hose covers the armor.<\/p>\n

Operation<\/strong><\/h5>\n

The control armorued cable can be used at temperatures from -50\u00b0C to +50\u00b0C and a rated air humidity up to 98% at temperatures up to +35\u00b0C. The laying without preheating is allowed at a temperature not lower than -7\u00b0C.<\/p>\n

The bend radius during the installation must be at least 10 outer cable diameters.<\/p>\n

Long-term permissible conductor heating temperature during operation is +70\u00b0\u0421.<\/p>\n

The service life of the cables is:<\/p>\n
