Application
Mining cable with optimized insulation wall thickness and optimized outer diameter. For underground mines as well as in tunnels, if monitoring of outer damages is required. Used for the connection of mobile operating equipment, in mines and underground excavations with hazardous environment, in stationary operation, e.g. high-voltage transformers in tunnelling. Cable type fulfils the requirements of DIN VDE 0118: Erection of electrical installations in mines.
