Key Features » Award winning patented single coil magnetic actuator mechanism » Environmentally friendly vacuum interruption produces no toxic by-products » Lightweight aluminium tank makes the GVR-38/10 easier to transport and install » Epoxy separable bushings are provided for quick disconnection of a faulted tower » Extensive use of insulated mouldings, in particular the bushings, the total number of parts have been reduced by a factor of x20 and the number of moving parts by x50 GVR 38 / 10 For Wind Farm Applications The GVR 38 / 10 is part of the award winning GVR family combining the high reliability of vacuum interruption with the controlled environment and high dielectric strength of SF6 in a compact, maintenance-free unit. (By utilising SF6 for insulation only, there is no health hazard from the toxic by-products of arcing) The patented, single coil magnetic actuator provides consistent performance and a dramatic reduction in moving parts. Materials and finishes have been carefully chosen for reliability - from the epoxy separable bushing interface to the neodymium iron boron magnets used in the mechanism. » No scheduled maintenance (excludes control batteries) » The unit can be supplied pre-wired to allow the circuit breaker to be remotely controlled » Unidirectional - senses fault current in either direction Application The GVR 38 / 10 is a stand-alone, circuit breaker, which can be used to isolate individual wind turbines for faults which do not affect other parts of the network. The power required to operate the control circuitry and mechanism is obtained from an in-built dc battery charger. The unit is supplied with a remote wall mountable control box, which houses the protection and control equipment. In addition to this the unit has the facility to be remotely controlled via a SCADA package. your power in safe hands HAWKER SIDDELEY SWITCHGEAR
