Packed in wooden cases (foam should be put inside for protection)
11kV Low Partial Discharge Window Type Compact Size Current Transformer
Current Transformer Application
Guangdong Sihui instrument current transformers are widely used in commercial, industrial and residential areas. They are for current measuring and protection, delivering high accuracy in current metering. Our current transformers are having a wide range, including epoxy resin medium voltage current transformers, epoxy resin Low voltage current transformers, oil immerged current transformers, dry-type high voltage current transformers and gas SF6 high voltage current transformers and so on.
Current 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 current measuring and protection, high accuracy
5). Less maintenance and pollution free
6). Easily operated and mounted
7). High mechanical strength and high dielectric strength
8).For cast resin current transformers, we have: post type CTs, contact cover enclosed CTs, wall gone-thru CTs, bar type CTs, special application CTs, plateau type CTs, TAT CTs , low voltage CTs, ring type CTs , window type CTs and CTs for residual current and so on.

1 Those listed in the table above are the routine parameters, if there is any different parameter required, we can design according to the technical parameters of the clients.
2 Detailed technical data and outline drawings are provided upon request.
1. The current 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.
