Voltage Transformer
- Oil Immersed Potential Transformer
- Major insulation of oil immersed voltage transformer adopts oil-paper compound insulation. All of major insulation, layer insulation and outgoing line insulation use insulation paper pad to wrap up. Iron core and winding will be vacuum dried and vacuum oil immersed after assembling. Products will carry out vacuum oiling and vacuum degass...
- SF6 Potential Transformer
- SF6 voltage transformer adopts SF6 gas with excellent insulation property, the working pressure is generally among 0.3~0.35MPa, and fibrous insulation material is not allowed to use in SF6, so insulation between windings adopts Mylar. To improve electric field, intermediate electrode is installed among primary winding and there are electr...
- Capacitor Potential Transformer
- Capacitor voltage transformer is to extract voltage by series capacitor and then transformed to be voltage source of meter, relay protection, etc. by transformer. It can make carrier frequency coupled to power transmission line to be used in long distance communication, distance measure, selective line high frequency protection, remote co...
Current Transformer
- Dry Insulation Current Transformer
- It is applicable to outdoors and low voltage system. It uses paperboard insulation between primary winding and secondary winding, after soaking with paint, it is installed with iron core and then plastic casing....
- Encapsulated Current Transformer
- At present it has been used in 66kV voltage transformer and mostly in 35kV and below transformer. Products whose primary winding, secondary winding and iron core are poured to be an organic whole ate called whole pouring type. According to different use and installation ways, products can be made into different structural type....
- Oil Immersed Current Transformer
- It is used in more than 35kV current transformer and its insulation is oil-paper insulation....
- SF6 Current Transformer
- Its insulating medium is SF6 gas. Independent SF6 current transformer adopts handstand structure and shell’s working pressure is among 0.3~0.35Mpa, so it should guarantee the obturation of shell and drive pipe under this pressure longtime and in order to improve root electric field, it will install electrodes screen to increase the ...
