Brand Story

Safety Begins with Perseverance in Original Aspiration

In 2016, an innovative seed quietly sprouted in the ancient capital Xi’an. With its extraordinary vision, Sinofuse Electric nurtured Sinok — a brand destined to drive transformation in the electrical industry.
In 2021, Sinok founded the Xi’an Sinok New Energy Technology Research Institute, engraving R&D and innovation into its brand DNA. Today, Sinok boasts a core product portfolio including excitation fuses, smart fuses, relays, BMS, and BDU, providing robust impetus to new energy vehicles, constructing intelligent protection for PV and energy storage systems, and creating unbreakable safeguards for data centers.
The story of Sinok is one of adhering to original aspirations, breaking through difficulties, and a group of dream-chasers contributing to the new energy industry with professionalism and dedication.

Technical Advantages

Outstanding Active Protection Capability

Outstanding Active Protection Capability

Controllable Protection Technology: Receives system control commands and actively disconnects at zero or low current, covering scenarios such as power cutoff during EV collision and overcharge protection of energy storage batteries. Full-Range Protection Technology: Achieves 0~30kA full-range breaking capacity, solving industry challenges including PV small current backfeed, energy storage cascading protection, and EV low-multiple overload protection. Multi-Loop Synchronous Disconnection: Meets collaborative protection requirements for complex topologies such as three-phase AC sides of electric drives.

Extreme Withstand and Breaking Performance

Extreme Withstand and Breaking Performance

High Short-Time Withstand Technology: Uses Maxwell simulation for electromagnetic force, Holm force, Lorentz force and compensation force matching to optimize design. Short-circuit withstand capability is further enhanced under the same product volume. High Breaking Capacity Technology: By using arc motion analyzers and high-speed cameras, this technology captures arc paths and monitors voltage-current relationships. Multi-dimensional technological innovation effectively raises the upper limit of voltage and current breaking. Low Resistance Technology: By using contact resistance analyzers, we study the influence of materials, pressure, contact form, spot quantity and process parameters on resistance. Through low-resistance materials, optimized contact structures and high-cleanliness control, contact resistance is greatly reduced.

Integrated and Intelligent BDU Architecture

Integrated and Intelligent BDU Architecture

Wiring-Free Design: Modular layout of core components + overmolding injection process, reducing circuit redundancy and structurally lowering failure risks. Electronic Pre-Charging Instead of Mechanical Solutions: Innovatively adopts electronic pre-charging to avoid relay fatigue failure at the source and improve space utilization. Intelligent BDU Solution: Integrates core BMU functional modules, enabling real-time data communication and precise remote control. Equipped with an autonomous safety protection mechanism, it provides comprehensive safeguarding for the stability of the power distribution system.
