110kV Toroidal Core SF6 Gas Insulated Capacitor High Voltage Transformer
Voltage Transformer Transformer Application
Guangdong Sihui instrument voltage transformers have a full range of indoor or outdoor, as well as single phase or three phases. Our voltage transformers are widely used in various switchgears of power grid, power plants, substations, railway, and coal mining industries and so on.
For epoxy resin insulated low voltage and medium voltage VTs, we have fused type, V-connection type, plateau type, pole-mounted type and post type and so on; For high voltage VTs, we have SF6 inductive voltage transformer, SF6 capacitor voltage transformer and oil- immerged voltage transformer and so on.
Voltage Transformer Main features
1).All outside parts, such as terminal box and mounting plate, are made of corrosion proof materials.
2).Low partial discharge 3).Matching different sizes switchgears 4).Used in voltage measuring and protection, high accuracy
5).Less maintenance and pollution free 6).Easily operated and mounted
7).High mechanical strength and high dielectric strength
Outline electrical parameters of voltagge transformer are as below
1).Primary voltage rating up to 1000 kV
2).Secondary voltage rating of 0.11kV, 230kV, 110/√3kV, 115√3kV or custom specified
3).Accuracy class up to 0.1 for metering; up to 3P, 5P for protection/relaying
4).Multi windings, up to 3 windings or more
5).Thermal limit outputs up to 2000 VA or custom specified
1 The transformers are packing with wooden packages, and must always stand up according to the direction mark of the packages (except for the 220kV current transformers, they are always packing and transport by lying down).
2 You must remove the wood plates of the top and obverse when you open the package, and then dismantle the 4 pcs M16 bolts which fix in the frame of the package, lift up the voltage transformer vertically and slowly from the package.
3 The clients must check the packages when they receive the voltage transformers, if a package has been broken, they must open the package to check the product together with the forwarder, note down the process and send to the manufacturer.
Quick response: We promise to quote you the best price within 24h.
Professional customized design: We have a professional team to meet any of your requirements.
