Pioneered the integration of double-breaker and phase-selective switching technologies, and developed the industry’s first compact dual-break vacuum circuit breaker suitable for high-altitude regions above 3,500 meters.
2016
Introduced the GLS-400 smart seamless power transfer system, integrating no-disturbance transfer technology with high-speed switching for backup power sources.
2015
Released the 40.5kV smart phase-controlled switch, extending our integrated primary-secondary control technology from the 12kV level to 40.5kV, further enhancing power system safety and reliability.
2011
Launched the first 12kV smart phase-controlled switch, which uses permanent-magnet phase-separated switching and phase-selective closing technologies to enable zero-crossing switching of capacitors and reactors, significantly improving power supply safety and quality.
2009
Our microprocessor-based Inrush Current Suppressor became the only phase-selective control product officially certified by State Grid Corporation of China for UHV transmission systems.
2007
Pioneered the seamless power transfer system for backup power, eliminating the fundamental design flaws of traditional ATS schemes and enabling zero-load loss during transfer operations.
2005
Invented an excitation inrush suppressor based on phase-control technology, protected by two invention patents, fundamentally solving voltage fluctuation caused by inrush currents and marking a major breakthrough in power system safety.
2003
Redefined the design principle of power transfer systems by introducing the concept of capturing the motor withstand voltage point instead of conventional synchronism criteria, enabling full-load preservation after primary source failure.
2002
Developed the first “multi-synchronization point shared-line auto-selector,” advancing synchronizing connection schemes in power plants and substations.
1999
Introduced the first microprocessor-based synchronizer capable of automatically identifying grid-connection types, laying the foundation for full automation of circuit breaker operations in substations and power plants.
1987
Established Shenzhen Intelligent Device Development Co., Ltd., the predecessor of GoLead Intelligent, as the first privately-owned high-tech enterprise registered in Shenzhen during the early stages of China’s economic reform.
1984
Our pioneering microprocessor-based synchronizer passed ministry-level appraisal at Chencun Hydropower Station in Anhui Province of China.
1982
Successfully developed and manufactured the world’s first microprocessor-based synchronizer, filling the global gap in this technology field.
