WHO WE ARE Grid Solutions, a division of GE Energy Connections, is a global leader in providing solutions that modernize the grid - managing and moving power from the power plant to the consumer. For over 100+ years, Grid Solutions has led in the development, design, manufacturing and installation of a broad range of integrated hardware and software solutions for utilities and energy intensive power users including oil and gas, petrochemical, mining, metals, water, critical infrastructure and telecommunication companies. Built on interpolatable designs, industry standards and deep domain knowledge,...

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 and...

Global Leader in Disconnectors Extensive Portfolio and Installed Base GE is a global leader for disconnectors (disconnect switches) since the 1960s, with 8 production facilities and 500.000+ installed poles in more than 130 countries around the world. The extensive portfolio includes disconnectors for AC applications up to 1,200 kV, for DC applications up to 1,000 kV and for railway applications. GE disconnectors have proven their reliability in the torrid climates of Arizona (USA), Australia and Sudan and in the extremely cold territories of Canada, Russia and Sweden, in the tropical weather...

Quality Orientated Facilities To remain the world's largest manufacturer of disconnectors means constantly improving our technologies. Our modern production facilities in Europe, the Americas and Asia are always seeking newer and more efficient organizational structures. GE facilities were developed to grow with the requirements of evolving technologies in order to perfectly manage the quality of components and the essential elements of disconnectors. Customer Benefits • High safety and reliability • Top performance • Certified quality according to ISO 9001 and ISO 14001 • Minimal maintenance •...

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 disconnector type...

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 circuit_up...

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 all environmental...

All GE disconnector manufacturing sites are ISO 9001 and ISO 14001 certified. GE has a clear environmental policy and the management believes that sustainable development of the company must be achieved in harmony with the environment and natural resources. Type Testing Facilities The GE disconnector competence center located in Noventa di Piave near Venice, Italy, is equipped with its own high performance testing facility. The high voltage test laboratory, built in 1973 and measuring 32 x 32 x 25 m, obtained ISO/IEC 17025 certification from the Italian accreditation entity Accredia in 2012....

Customer Intimacy From project design through commissioning to after sales customer service, GE places great emphasis on maintaining long-term relationships with its clients. The GE worldwide network of representatives remain in close contact with their customers around the world: GE helps utilities and industry to tackle grid challenges. Service GE specialists are available to ensure rapid disconnector installation and erection supervision, if the customer requires it. Training Training courses are available for all of GE's principle units, either on-site or in GE training facilities. These...
