  Gas Insulation High Voltage 220kV 230kV Current Transformer for Substation

 Product Description  

1. 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. 

2. 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.
