Type description Pollution level With protective class Current transformer It is outdoor, single phase and oil immersed hair-pin type current transformer, which is used for metering and relay protection of 66kV, IEC Standard: IEC60044-1 (Current Transformer) National Standard: GB1208 {Current Transformer) GB311.1 (Insulation co-ordination for high voltage transmission and distribution equipment) Altitude: less than 1000m Environment pollution level: II, Ilk IV System Rated Voltage: 66kV System Highest Voltage: 72.5kV System Rated frequency; 50Hz or 60Hz System neutral earthing method: non-effectively earthed • It is oil/paper insulation system, the primary insulation is wound from high voltage cable paper. It will be immersed with transformer oil after desiccating under vacuum. It has advantages of stable and reliable performance of insulation, rich successful experience, a long lifetime and convenient • Perfect fluidity performance of transformer oil is good for heat Dissipation, it also has self recover ability for the failure of partial discharge caused by air bubble and • The current ratio can be changed easily by change the connection method of connecting plate on oil conservator to series or parallel Connection. • Hermetically sealed stainless steel metallic bellows is installed on the top, which protect the transformer oil form moisture and extend the life time, also there is a oil level gauge on the bellows for observing the changing of • There is a multi function oil drain valve on the base, which make it more convenient for sampling, draining and • The primary terminal and secondary terminal board are made of epoxy casting, the seal performance is more The oil conservator and base etc use DACRAL (Zinc/Chromate coatings) for resistance to corrosion, which gives a high degree of corrosion resistance. • The primary over-voltage protection device and secondary opencircuit over-voltage protection device can be provided according to the requirements of user.
