HYDRA Tunneling Cable Reel

HYDRA cable reels are specially designed and manufactured for feeding mobile power systems that have limited installation space. This cable reel is manufactured with slip rings inside the spool and support frame of the drum without a shoulder in order to adapt to any lack of space. Power is transmitted via electrical cables, low or medium voltage, to machines operating in tunnels, in yards or in harsh environmental conditions. Therefore HYDRA cable reels are integrated into other machines as a component.
