SPLIT-CORE CURRENT TRANSFORMER

The LK-10 series open‑type current transformers are suitable for current measurement, power extraction, and microprocessor‑based protection in complete switchgear systems operating at 10 kV and below. Featuring a compact footprint, lightweight construction, and an open‑type design that facilitates installation, these devices are widely employed in compact, fully insulated ring‑main units.

SILICON STEEL CORE

All types of iron cores manufactured by our company—such as toroidal silicon steel cores, R‑type silicon steel cores, and CD‑type silicon steel cores—are crafted using genuine, virgin materials. From strip slitting and winding to annealing, varnish impregnation, and notching, every production step is rigorously controlled to ensure product excellence. In the magnetic core industry, we are committed to delivering only premium-quality products. With the most competitive pricing, top‑notch quality, and professional service, we are dedicated to serving the electrical industry.
