China Quality Instrument Transformer Manufacturer

Junray Electrical’s circular residual current transformer is specifically designed for residual current detection in low-voltage power distribution systems. It serves as a core sensing component for electrical fire monitoring, earth leakage protection, and fire-safety power supply monitoring systems. Widely used in commercial buildings, industrial facilities, residential distribution networks, and data centers, it ensures reliable earth leakage monitoring for low-voltage electrical safety.

Junray Electrical is a professional manufacturer and supplier of cable-type piercing current transformers. This cable-type piercing Rogowski coil is an integrated AC current monitoring sensor designed specifically for outdoor scenarios lacking external power sources. It highly integrates an insulation-piercing self-powering module with a flexible, split-core Rogowski coil; it derives operating power by piercing the insulation of the target cable—eliminating the need for additional power wiring—while simultaneously performing precise AC current acquisition.

Junray Electrical’s busbar-type coil current transformer is designed for the electronic measurement of AC current. It utilizes magnetic shielding technology to significantly minimize errors caused by the conductor's position within the aperture or proximity to external conductors. Its cable-tie mounting method simplifies installation—eliminating the need to dismantle busbars—and allows certified electricians to perform compliant "live" installations in low-voltage scenarios, thereby drastically reducing construction costs and downtime losses associated with outdoor power distribution upgrades.
