HYEE The Famous Trademark of China

A Professional Manufacturer of 0.5~330kV Instrument Transformer

17 YEARS MANUFACTURING EXPERIENCE

Presently our 220/230kV CT has been sold to Pakistan, Mongolia, Bangladesh, Syria, North Korea, Chile, Peru and so on, also  in China State Grid we have supplied more than 1000pcs without any quality problem happened.

Here we provide 2 different designs for your selection.

Type One: live tank, its secondary windings are located at the top of product,which we also called it “ top head” The primary winding in a live tank CT is constructed of short length. This is done intentionally as a shorter shape provides higher levels of durability and  strength when the primary winding is exposed to short time current.

Type Two: dead tank, its secondary widnings are located at bottom of product,which we also called it “bottom head”. The primary winding in a dead tank CT is insulated similarly to other current transformers and is then brought down to the bottom tank  where it is earthed. Further, the primary is made to pass through an insulated porcelain. In Dead tank CTs, the length of the primary conductor decides the mechanical force exerted on the transformer when it is exposed to  short time dynamic current. It is therefore important to increase the length of the primary conductor to ensure that there is no damage to the transformer when it is exposed to high currents.
