Lugao takes pride in being Cable Core Type Current Transformer manufacturer,The LC-10/24/35kV CABLE CORE TYPE current transformer is well-suited for the measurement of current and microprocessor-based protection of distribution equipment in AC power systems with cable lines operating below 35kV.     Its versatility extends to applications in compact fully insulated Ring Main Units, combined substations, and cable take-off boxes, owing to its compact design, lightweight construction, open feasibility, and easy installation.     Notably, this current transformer can be directly installed on connected output and input cables.

This current transformer features a core for the measuring winding made from a new type of magnetic conductivity material.     Its high permeability, low saturation magnetic induction strength, and excellent stability ensure precise measurements with a low instrument security factor.     The protective winding employs high-quality imported silicon steel sheets processed with advanced technology.

The ring core and secondary windings are enclosed in a flame-retardant plastic shell made of high-quality epoxy resin, providing moisture-proofing, stable performance, and maintenance-free operation.     The transformer is compact, lightweight, and space-efficient.     Installation is simplified by passing the cable through the inner hole, ensuring a straightforward, fast, harmonious, and aesthetically pleasing process.
