Cable KVVGEng 7x4 control EUROPAN CABLE (7483)

Description

KVVGEng – Control cable with copper conductors, polyvinyl chloride insulation, a common aluminum foil screen and a flame-retardant polyvinyl chloride sheath. Scope Intended for fixed connection to electrical appliances, devices, terminal assemblies of electrical switchgear with a rated AC voltage of up to 660 V, a frequency of up to 100 Hz or a DC voltage of up to 1000 V. Used for laying in rooms, channels, tunnels in the absence of mechanical effects on the cable in aggressive environments and the need to protect electrical circuits from the effects of external electric fields. The cable can be laid outdoors, provided that they are protected from mechanical damage and direct sunlight. 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 (class 1 DSTU EN 60228). Insulation - polyvinyl chloride plastic compound. General screen of aluminum foil. Outer sheath - polyvinyl chloride plastic compound, which does not support combustion. Operation The cable is intended 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 bending radius of the cable when laid at ambient temperatures not lower than 0°C is not less than: - three cable diameters - for cables with an outer diameter of up to 10 mm inclusive; - four cable diameters - for cables with an outer diameter of over 10 to 25 mm inclusive; - six cable diameters - for cables with an external size of more than 25 mm. The permissible continuous heating temperature of the cable cores during operation is 70°C. The service life of the cable is at least 20 years when laid in the ground (trenches) and on overpasses, provided that it is protected from direct sunlight, and 25 years when laid in rooms, canals and tunnels.
