Why a Disconnector? Taking economic savings to an extreme, some companies choose to reduce their safety equipment. For over 100 years, the visible gap provided by disconnectors (or disconnect switches) has made the difference between life and death - not having them is a risk simply not worth taking. Disconnectors are built in a variety of physical forms. Based on the substation configuration, different designs are available according to overhead and interphase clearances. When necessary, space saving configurations can be taken into account in your design by, for example, using pantograph...

CENTER BREAK In the center break design, the two arms rotate and the disconnector opens in the center. It is the most commonly used disconnector and offers ratings up to 550 kV. The center break requires an increased interphase distance. V TYPE CENTER BREAK The V type center break has two moving insulators mounted on a small common base. It can be mounted on simplified and cost-effective supporting structures. Available up to 145 kV. EARTHING SWITCHES Earthing switches are used to connect to ground sections of a substation or HV line to ensure personnel safety. They can be combined with any...

KNEE TYPE The knee type has two fixed and one moving insulator and requires limited overhead clearance thanks to its folding-arm design. PANTOGRAPH and SEMI-PANTOGRAPH Both disconnector types feature one fixed and one rotating insulator and are usually used to connect the two busbars of double decker substations. Placed diagonally to the axis of the busbars and feeder, they offer a very clear - and therefore safe - arrangement and space saving solution. Nominal current up to 4,000 A Short circuit_up to 80 kA, 1 s Ratings Voltage123 kV to 1,000 kV Nominal current up to 5,000 A Short...

GE also otters solutions to interrupt induced currents with ground switches. These currents occur when an earthed line runs parallel to a live line. GE manufactures various models of earthing switches which meet IEC 62271-102 class A or B and for inductive current values of up to 525 A at 70 kV. Standards & Environmental Conditions Interrupting Capabilities GE has developed products that meet international IEC and IEEE standards, as well as GB Chinese national standards. GE's range of disconnectors can be adapted to meet almost any specific customer requirement for virtually...
