LZZB8-20 series high-voltage current transformerDetailed product description：

The LZZB8-20 series high-voltage current transformer is an epoxy resin cast insulation fully enclosed pillar type product, suitable for current and energy measurement and relay protection in power lines and equipment with a rated frequency of 50Hz or 60Hz and a rated voltage of 20kV and below. The product complies with the standards of IEC44-1:1996 and GB1208-1997 "Current Transformers".



Structure Introduction

The LZZB8-20 series high-voltage current transformer is a fully enclosed pillar structure with epoxy resin casting insulation, resistant to pollution and moisture, and suitable for installation in any position and direction. The single variable ratio primary winding is fixed. The dual ratio primary winding adopts series and parallel connection. Changing the wiring direction once can result in two current ratios. As shown in the diagram, the series connection is 100/5A, and the parallel connection is 200/5A.
