Second National High-Voltage Testing Technology Training and Assessment Held in Xi'an with Xuzhihui Support 2026-10-29 Second National High-Voltage Testing Technology Training and Assessment Held in Xi'an with Xuzhihui Support XI'AN, China — From June 28 to July 5, 2026, the Second National High-Voltage Testing Technology Training and Professional Competence Assessment was successfully held in Xi'an. High-voltage testing specialists from across China's power industry gathered for intensive theoretical training and hands-on assessment, with Xi'an Xuzhihui Electromechanical Technology Co., Ltd. ("Xuzhihui") providing full support throughout the event. Theory Training: Building Solid Foundations Under Expert Guidance From June 28 to July 3, the "2026 Second National High-Voltage Testing Technology Training Program," hosted by the Beijing Electric Power Training Center, opened in Xi'an. The curriculum covered a wide range of specialized topics, including: application of high-voltage testing technology in UHV (ultra-high-voltage) projects; application of series resonant devices in power testing; common fault analysis and testing techniques for instrument transformers; verification techniques for current and voltage transformers; testing methods for on-load tap changers and zinc oxide surge arresters; grounding technology for electrical equipment and partial discharge detection. Drawing on years of technical expertise and on-site experience in high-voltage testing, Mr. Zhang Zhencun, Chairman of Xuzhihui, was invited to serve as a guest instructor and delivered a special session on "Power Cable Testing and Detection." Classroom interaction was lively and the learning atmosphere was enthusiastic. Practical Assessment: Putting Skills to the Test From July 3 to 5, the professional competence assessment for high-voltage testing personnel was organized by the National High-Voltage Metrology Station and hosted by Xuzhihui. The hands-on assessment took place at Xuzhihui's factory, where the company had fully prepared the venue and calibrated testing equipment in advance. On the assessment day, the practice area presented neatly arranged equipment ready for the candidates. Conducted in accordance with specification T/CEC 315—2020, the assessment was divided into Class I and Class II levels, comprehensively evaluating candidates' hands-on ability and on-site adaptability.

XZH TEST Launches Fully Domestic Export-Edition Power Testing Vehicle for Belt and Road Substations 2026-10-24 XZH TEST Launches Fully Domestic Export-Edition Power Testing Vehicle Chinese Intelligent Manufacturing Goes Global to Support High-Quality Power Development Along the Belt and Road XZH TEST Electromechanical Technology Co., Ltd. has launched its Export-Edition Power Testing Vehicle, a fully domestically developed, self-contained mobile test platform designed to address the growing demand for grid operation and maintenance, fault location, and equipment condition assessment across the substations and power networks of Belt and Road countries. As global energy infrastructure investment continues to accelerate, grid construction in many countries along the Belt and Road is advancing rapidly, and the demand for grid operation and maintenance, fault diagnosis, and equipment condition assessment is rising every day. Traditional on-site power testing still faces persistent challenges: a proliferation of scattered and independent test instruments, heavy and laborious equipment handling, complex on-site wiring, and the frequent lack of a reliable power supply in remote field environments. These factors consume considerable manpower and resources, constrain grid operation and maintenance efficiency, and make it difficult to fully safeguard power supply reliability. Building on its independent R&D strengths in domestic power testing equipment, XZH TEST has drawn on years of technical accumulation and engineering experience to develop a fully domestic, export-oriented power testing vehicle. Through scientific spatial layout and a highly modular, integrated design, the vehicle consolidates a complete suite of self-developed professional power testing instruments onto a single mobile platform, creating a mobile “power comprehensive test laboratory” that can be deployed directly to the site. With the strength of Chinese intelligent manufacturing, XZH TEST delivers an integrated testing and maintenance solution for overseas power grids, demonstrating the technical capability and product reliability of domestic power testing equipment. Fig. 1  The XZH TEST Export-Edition Power Testing Vehicle on the road Full-Stack Domestic System Integration Delivers One-Stop Substation Testing Coverage Every core testing instrument inside the vehicle is independently developed and manufactured by XZH TEST, eliminating dependence on external equipment. The integrated platform delivers efficient and accurate on-site testing, commissioning, and comprehensive condition assessment of key primary and secondary substation equipment, covering the full range of testing requirements for power transformers, instrument transformers, high-voltage switches, lightning arresters, power cables, relay protection, and grounding grids. Power Transformer Testing System: integrates the XHTX1318AJ transformer characteristic tester, XHZ1320 DC resistance tester, XHBB128B ratio and group tester, XHZK1620 low-voltage short-circuit impedance tester, XHBX1502 transformer winding deformation tester, XHYS101A transformer oil dielectric loss tester, XHYY102 insulating oil withstand voltage tester, and XHXC105A demagnetizer. Instrument Transformer Testing System: integrates the XHTX206 instrument transformer characteristic tester. High-Voltage Switch Testing System: integrates the XHJJ302AC circuit breaker mechanical characteristic tester, XHHL3200 contact resistance tester, and XHJL309 sulfur hexafluoride (SF6) comprehensive tester. Lightning Arrester Testing System: integrates the XHJS401A arrester monitor calibration tester and XHDD405 live zinc-oxide (ZnO) arrester tester. Power Cable Detection and Testing System: integrates the XHGG502A cable fault tester, XHDD503E cable fault locator, XHGX507C cable comprehensive tester, XHHV5354TSC high-voltage pulse generator, XHHD520 outer-sheath fault comprehensive assessment instrument, XHSC60Q intelligent burn-down bridge, XHDL51X cable quality analyzer, HDPJ80 very-low-frequency (VLF) dielectric loss tester, XHOW56035 cable oscillating-wave partial discharge detector, XHZK550 cable broadband impedance analyzer, XHZS506YS cable piercing device, XHSB505B live cable identifier, and XHZL509 cable length meter.

A domestically produced 6 kW variable-frequency auxiliary generator supports the continuous, stable operation of the entire suite of precision test instruments even in field environments with no external power, so the team can begin work immediately on arrival without building a separate power supply. Instruments inside the vehicle are mounted with shock-proof, reinforced installation to withstand the vibration of long-distance transport. A complete package of safety protection, grounding protection, and ventilation and heat-dissipation systems enables the vehicle to adapt to a wide range of overseas working conditions, including high temperatures and sandstorms, fully meeting the practical requirements of substation inspection, preventive testing, and emergency fault repair in the field.
