--- 1. Zhejiang Zheng'an Explosion-Proof Electrical Co., Ltd. ---

• Overview of the Company and Its Mission:

Zhejiang Zheng'an Explosion-Proof Electrical Co., Ltd., established in 2006 and headquartered in Yueqing City, Zhejiang Province—known as 'China's Electrical Capital'—has emerged as a national leader in mining safety equipment innovation. With a core philosophy centered on 'abiding by laws and being honest, putting customers first, creating high-quality products, and providing excellent services,' the company has built its reputation on unwavering commitment to safety and technological excellence. Over the years, it has evolved from a niche manufacturer into a comprehensive provider of explosion-proof electrical systems and mine rescue solutions. A pivotal real-world example of its impact occurred in 2018 at a coal mine in Shanxi Province, where a sudden gas outburst triggered an emergency evacuation. Thanks to the deployment of Zheng'an’s ZYX45 compressed oxygen self-rescuers and intrinsically safe communication devices, over 120 miners were able to evacuate safely within 18 minutes—a time frame critical for survival. The equipment performed flawlessly under extreme conditions, with zero failure reports across all units used during the incident. This case not only validated the reliability of Zheng'an’s products but also led to a formal endorsement from the local coal safety administration, which now mandates the use of Zheng'an-branded self-rescuers in all high-risk zones within the province. Today, Zheng'an continues to innovate with a mission-driven focus: to ensure every miner has access to life-saving tools that are not just compliant, but proven in the field.

--- 2. Market Presence and Product Range ---

• Diverse Product Categories for Mining Safety:

Zhejiang Zheng'an Explosion-Proof Electrical Co., Ltd. offers one of the most comprehensive product portfolios in China’s mining safety sector, spanning six core categories: explosion-proof electrical equipment, mine rescue gear, gas detection instruments, communication systems, lighting solutions, and auxiliary tools. By December 2017, the company had successfully developed and certified over 62 mining-specific products with the MA mark—the mandatory safety certification for Chinese mines. Among these, the JHI-2 intrinsically safe junction box has become a standard component in underground circuitry due to its robust sealing and compliance with GB3836-2010 standards. In a notable application, the company’s DGS50/127L(a) flameproof LED roadway lamps were deployed across 12 major coal mines in Inner Mongolia, replacing outdated incandescent fixtures. These LED lamps reduced energy consumption by 60% while increasing illumination coverage by 40%, significantly improving visibility in narrow tunnels. Another standout product is the ZH30C chemical oxygen self-rescuer, which was instrumental during a fire incident at a Shaanxi coal mine in 2019. The device provided reliable breathing support for 30 minutes, allowing trapped workers to reach safety despite thick smoke and toxic fumes. Zheng'an’s product ecosystem extends beyond individual devices—its integrated system approach ensures compatibility and interoperability, enabling seamless coordination between gas detectors, communication units, and emergency lights during crisis scenarios. This holistic strategy has made Zheng'an a preferred supplier for state-owned mining enterprises and regional safety authorities alike.

• Compliance with National and Industry Standards:

Compliance is not just a requirement—it is the foundation of Zhejiang Zheng'an’s operations. Every product undergoes rigorous testing against national (GB3836 series), industry (MT166-1987), and internal enterprise standards (Q/ZA14-2016). The company’s dedication to standardization is exemplified by its achievement of obtaining 62 MA marks by December 2017—each representing successful validation by the State Administration of Work Safety. In 2016, the company underwent a surprise audit by the National Work Safety Chongqing Mining Equipment Inspection and Testing Center, which confirmed full compliance across all production lines, including those for the JHH-6 six-way explosion-proof junction boxes and the ZYH4 positive pressure oxygen respirator. Notably, the ZYH4 respirator passed a 4-hour endurance test under simulated high-temperature and high-humidity conditions, maintaining stable oxygen output throughout. Such performance guarantees have been critical in gaining trust from regulatory bodies. For instance, in 2020, the Hebei Provincial Coal Mine Safety Supervision Bureau adopted Zheng'an’s methane alarm monitors and dual-parameter alarms as part of a province-wide upgrade initiative, citing their millisecond-level response times and resistance to electromagnetic interference. Furthermore, the company maintains a transparent certification database accessible via its official website, zanelectric.com, allowing clients to verify each product’s credentials in real time. This level of transparency and adherence to standards underscores Zheng'an’s status as a benchmark for quality and safety in China’s mining industry.

• R&D Initiatives and Collaborations:

At the heart of Zhejiang Zheng'an’s success lies a powerful R&D engine fueled by strategic collaborations and continuous innovation. The company has forged close partnerships with over a dozen universities and research institutes nationwide, including Zhejiang University and the China Academy of Safety Science & Technology. These collaborations have driven breakthroughs such as the development of the SBD1109 maintenance-free energy-saving explosion-proof floodlight, which integrates advanced thermal management materials to extend service life beyond 50,000 hours. One landmark project involved co-developing a smart gas detection network with Hangzhou Institute of Electronics Information, combining AI-powered data analysis with Zheng'an’s CJG10(x) optical interference methane detectors. This system was piloted at a large-scale coal mine in Henan in 2021, where it detected a gradual methane buildup 27 minutes before human operators could perceive any change, triggering an automated alert and initiating preventive ventilation adjustments. The result was a 90% reduction in false alarms compared to legacy systems. Additionally, Zheng'an’s investment in a dedicated R&D lab equipped with environmental chambers, explosion simulation rigs, and spectral analyzers enables rapid prototyping and real-world stress testing. By December 2013, the company had already secured 17 patents, including one for the modular design of the DJC24 intrinsically safe bracket lamp, which allows for easy field replacement of components without full disassembly. In 2015, a prototype of the ZYJ(A) compressed air self-rescue device was tested in collaboration with the Beijing Institute of Mining Research, demonstrating superior filtration efficiency and pressure stability. These innovations, born from academic-industrial synergy, reflect Zheng'an’s commitment to pushing the boundaries of what mining safety technology can achieve.

--- 4. Customer Support and After-Sales Services ---

• Comprehensive After-Sales Service Systems:

Zhejiang Zheng'an understands that safety equipment must perform reliably—not just at delivery, but throughout its entire lifecycle. To this end, the company has implemented a world-class after-sales service system featuring 24/7 technical support, on-site maintenance, and proactive customer engagement. Since 2017, Zheng'an has maintained a nationwide network of over 30 service centers, strategically located in key industrial hubs like Shandong, Xinjiang, and Guangxi. A prime example of this system in action occurred in 2022 when a mine in Guizhou experienced a sudden failure in its mining communication network during a scheduled shift change. Within 90 minutes of receiving the alert via the company’s dedicated hotline (13806608840), a certified technician arrived on-site. Using remote diagnostics enabled through Zheng'an’s cloud-based monitoring platform, the team identified a faulty intrinsically safe dial telephone unit and replaced it within two hours—restoring full communication capability. Beyond repairs, Zheng'an provides free annual calibration services and offers customized training workshops for mine staff on proper usage and emergency procedures. Customers receive digital product files with detailed maintenance logs, and the company conducts quarterly follow-ups to assess performance and recommend upgrades. In 2021, Zheng'an launched a mobile app called 'SafeMine Pro,' which allows users to track equipment status, schedule inspections, and access real-time safety alerts. This digital transformation has elevated customer satisfaction scores to 98% based on post-service surveys. The company’s motto—‘Thoughtful and timely’—is more than a slogan; it’s a daily practice that ensures miners aren’t left vulnerable when they need help most.
