EVAVB EVAVB-F2

Uo/U 3.6/6 kV NBN C 33-121 and modifications No 1 and 2
The three-core cables with insulation of polyvinylchloride (PVC) - armored type are designed for transfer and distribu­tion of electrical power in networks with retardant voltage of 6000 V and in industrial plants. For cable EVAVB the sheath is PVC compound and for cable EVAVB - F2 - PVC compound.
 
The cables are for fixed assembly in lines with unlimited flame difference levels, for underground laying, in cable ducts, con­duits, trenches, pipes, shafts over shelves and grills directly underground in ditch.
