The disconnectors are for providing isolation of power equipment from the network, a disconnector is suitable for switching small currents or where no significant change in voltage occurs across the terminals. The option of earthing sections of power systems can be made available by providing each disconnector pole with one or two earthing switches.
Standards:
The GW4 disconnectors are designed as per IEC 62271-102 and IEC 62271-1 standards. Other international regulations can be met on request.
Type tests on the disconnectors are carried out by accredited testing laboratories in accordance with the latest regulations. Comprehensive electrical and mechanical routine tests are carried out on the poles and operating mechanism of each disconnector ensuring world class quality.
Design:
The center break disconnector consists of three poles. Each pole consists of a main blade that moves in a horizontal plane, two rotating support insulators, and a frame. The modular design of center break disconnector offers various possibilities to adapt the switchgear to changed requirements in substations.
The main blade consists of an U-shaped aluminium tube, in which the male and female silver-plated copper fingers are installed.
The frame is made of an square tube in which the bearing housings and the turntables are installed. The turntable is supported by two roller bearings. The bearing housing is sealed and filled up with grease, to ensure a long lifetime. All steel parts of the disconnector are hot-dip galvanized.
The disconnectors can be equipped with insulators in accordance with IEC, ANSI or DIN specification and with one or two earthing switches.
