Motor
operating drive

The primary function of a motor operating mechanism is to provide reliable remote operation of disconnectors by
means of a reciprocating (up-down motion) or torsional (rotating motion) operation. Hughes produces a wide range of different motor operation mechanisms for disconnectors and earth switches. The product range covers everything from small low voltage applications in tram to medium voltage applications in rail and electrical distribution to heavy motor mechanisms in high voltage disconnector application.
