Outdoor Voltage Transformer and Current Transformer Metering Instrument Transformer CT & VT

Gugangdong Sihui Instrument transformers have strong wihstand of thermal shock, overload capbility, low partial discharge, low noise. Therefore, our transformers sell well on the market. We a have wide variety of options, such as current transformers, voltage transformers, dry-type power transformers, transducers, reactors an all kinds of trucks for switchgear. Transformers are rated from 6kV up to 550Kv, which can be applied to indoor and outdoor condition. They are widely used in various switchgears of power grid, power plants, substation, railway and so forth.

1. Outdoor Voltage Transformer and Current Transformer Metering Instrument Transformer CT & VT 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.
