MV Cable
RHZ1-AL cable is a type of medium voltage halogen free power cable designed for fixed installations, typically used for power distribution in networks. The "RHZ1" designation indicates a flame-retardant, low-smoke cable, while "AL" specifies that it has an aluminum conductor. These cables are commonly used in environments where fire safety is crucial, such as transformer stations, infrastructure, and data centers. Where appropriate, waterblocking measures can be applied should it be installed in cable ducts liable to flooding. The suffix RHZ1-OL references a longitudinal waterblock applied above and below the screen, whilst a dual waterblock RHZ1-2OL has the longitudinal swellable tapes supplemented by swellable yarns or powders added to the conductor to make it watertight.
