TUNNEL CABLES
3GSEYQY
Application
3GSEYQY cables are used for the connection of mobile operating equipments. In mines and underground
excavations with hazardous environments, in stationary operation, e.g.highvoltage transformers in mining and
tunneling. It can be used also for powering main pannels and switchboards in tunneling applications.
