Product Name: Power Usage and Autotransformer Coil Number Ferrite Core Transformer
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.
3. Technical Specifications ( IEC 60076-11:2004 )
3.1. The products are especially suitable for installation in draw-out type or fixing type switchgears as well as for power plants or substation self-consumption transformers or those places where small space, fire-control, moisture-proof, are needed. Those up to 10kV can be installed in a 650~1200mm wide switchgear, up to 20kV in a 1000mm wide switchgear and 35kV in a 1400~1600mm wide switchgear.
