Summary
LABN6-35 current transformer (LABN6-35) is a kind of outdoor fully-enclosed capacitance oil-paper insulated current & electricity measuring and relay protection device used in alternative current (AC) power system with maximum voltage of 140.5kV and rated frequency of 50Hz or 60Hz.
LABN6-35, with 3 or 4 pieces of secondary windings, adopts secondary measuring windings made of highly magnetism-conductive microcrystalline alloy, able to guarantee the measuring precise to Level 0.2 or 0.2S.
The oil conservator adopts aluminum alloy and the oil tank is drawn and formed by a whole piece of excellent steel plate. Sealed structure can extend the aging period of gasket rings and keep reliable sealing performance. Enclosed structure can guarantee the running quality of insulated oil and keep safe and reliable running.
