Cable VBbShvng 4x240 power EUROPAN CABLE (67790)

Description

Cable ВБбШвнг 4х240 power EUROPAN CABLE ВБбШвнг – Power cable with copper conductors, polyvinyl chloride insulation and protective covering of type БбШв, which does not support combustion. Scope Designed for transmission and distribution of electrical energy in stationary installations at a nominal alternating voltage of 0.66; 1 kV, frequency 50 Hz. Used for laying in the ground (trenches), rooms, tunnels, canals, mines (except for laying in blocks) and partially flooded structures, with various corrosive conditions, as well as outdoors, if the cable is not subjected to significant tensile forces, but if there is a risk of mechanical damage during operation. The index "ng" means that this cable does not support the spread of combustion, which is especially important in places with a high probability of ignition and increased safety requirements. Construction Conductor cores - copper, single-wire or multi-wire, round, sector (class 1, 2 DSTU EN 60228). Insulation made of polyvinyl chloride plastic compound. Armor made of galvanized steel tapes. Outer sheath - extruded PVC protective hose that does not support combustion. Operation The cable is designed for stationary operation at ambient temperatures from -50°C to +50°C, relative humidity up to 98% at temperatures up to 35°C, including for laying outdoors. The cable can be laid without preheating at temperatures not lower than -15°C. The minimum bending radius during installation must be no less than 7.5 times the outer diameter of the cable. The permissible continuous heating temperature of the cable cores during operation is 70°C and the maximum permissible temperature during short-circuit currents is 160°C. The permissible heating of the cable cores in emergency mode is no more than 80°C.
