N2XH/ N2XCH

Cable

Application and Description

N2XH power cables with enhanced resistance to fire are used mostly in areas where harm to human life or material must be prevented in case of fire such as industrial and public buildings, hotels, subway systems, hospitals etc. These cables are suitable for dry and wet environments as well as for outer application but are not suitable for direct burial into earth or water.
