Intelligent Drop-Out Fuse (Push-Pull Type)

New Products / New Technology

TRW12-12 intelligent drop-out fuse is designed for 10 kV outdoor distribution systems, serving as a primary-side short-circuit protection device for lines and transformers. It is economical, durable, and highly adaptable to outdoor conditions. Building on the conventional RW12 design, this product integrates IoT and sensor technologies, retaining overload and short-circuit protection while adding online status monitoring and proactive fault‑alert capabilities. It employs a mechanical push‑pull arm actuation mechanism and supports three operating modes: local remote control, remote operation, and traditional manual operation. Equipped with a protective cover and featuring excellent arc‑extinguishing performance, it serves as a core terminal in the smart upgrade of distribution networks.

Intelligent Isolating Switch

New Products / New Technology

The DGDW1-12 outdoor high-voltage intelligent disconnect switch is a 10 kV, 50 Hz single-phase AC device, suitable for no‑load switching of power supplies. It supports local remote control, remote operation, and conventional manual operation, eliminating the need to climb poles. With human–machine isolation at high voltage and precise, safe opening and closing, it serves as a core terminal in the smart upgrade of distribution networks.

Intelligent segmenter

New Products / New Technology

The FDK-24(E) intelligent electric sectionalizer is an automated switch for distribution network fault isolation, featuring automatic disconnection under no‑voltage and no‑current conditions. It can store the number of fault operations, accurately identify various types of line faults, and upload operational data. The device incorporates a single‑phase built‑in independent power supply, ensuring low line losses and stable operation, while eliminating the need for an external control cabinet for a more compact design. It employs a mechanical push‑pull actuation mechanism and supports three operating modes: local remote control, remote operation, and conventional manual operation.
