Application

Cables are intended for transmission and distribution of electrical energy in power and lighting networks of 220 V and 380 V, 50 Hz AC. Installation and operation – external input to homes and outbuildings in the networks of 220 and 380 I and II parts of of icing (АВВТ wire) or III and IV parts icing (wire АВВТУ wire). Wires are used in conditions of  increased wires safety  from external climatic and mechanical effects
