Partial Product Parameter
The SDH - 0.66 current transformer adopts PC flame - retardant material, and the magnetic - conducting material is an annealed toroidal core to ensure the accuracy of the product at levels 0.2 and 0.5. For ultra - high accuracy levels such as 0.2s and 0.5s, only superconducting magnets can meet such accuracy requirements.
SDH - 0.66 is applicable to power systems with a rated frequency of 50Hz and a rated voltage of 0.66kV, 0.69kV, 0.5kV and below for electric energy metering, current measurement and relay protection.
This current transformer of Huling is for indoor use, installed inside distribution cabinets and boxes. It features a novel magnetic circuit design, advanced compensation methods, exquisite processing techniques, safe and reliable performance, and a small and beautiful appearance.
The outer shell is made of high - strength flame - retardant PC with a fully - enclosed structure and a flame - retardant rating of V1. The internal core is made of high - quality grain - oriented silicon steel sheets. The wire diameter is strictly selected according to the economic current density to ensure less temperature rise. With advanced and reliable testing equipment, it ensures compliance with quality standards.
It has square and round hole types, suitable for single - root or multiple - root cable penetration or single - root busbar penetration. It has a complete product series, a wide variety of specifications, and a wide application range.
