Customer ServiceTypical configuration of a capacitor bushing. [...] In high-voltage capacitor bushings, there is maximum field intensity at the edge of the aluminum foil and where foils overlap. Any technique decreasing much field intensity in those regions will significantly optimize the bushings' electrostatic characteristics.
GIPRO manufactures customized capacitor-bushings from both indoor casting resin as well as from cycloaliphatic epoxy resins for outdoor applications. One speciality of our solutions is the treaded-ring, which GIPRO casts with the same epoxy cast-resin as the capacitor bushing. So you get a one stop-solution for your bushing supply.
The bushing platform enables to separate selection of shields and terminals of the both sides (oil and cable). Draw lead (DL) system (Fig.3) for greater ease of assembly, when the required current capacity is at a relative lower rate. The draw lead is the current path through the bushing.
The design of any type of electrical bushing takes into account the following requirements and aspects: The central conductor of a bushing should be able to carry the anticipated load, or fault currents, without overheating the surrounding insulation (which can lead to abnormal loss of life).
High voltage condenser bushing isone of the important component that is widely used in the high voltage system. At high voltage levels more than 52kV the distribution of electric field in condenser bushing is irregular between the lead conductor and the grounded metallic flange.
The tasks of a bushing are current carrying and connection of high-voltage potentials through a separating earthed surface in different insulating media to connect the high voltage line to earth, each instrument transformer contains a bushing. Oil-paper isolated bushings and SF 6 isolated bushings are discussed.
