The 2025 Shanghai Power Storage Exhibition has begun, and XZH TEST invites you to visit N5E03! 2025-11-19 Today, the Shanghai New International Expo Centre welcomes the grand opening of the 32nd China International Power Equipment and Technology Exhibition & Shanghai International Energy Storage Technology and Application Exhibition, a major annual event for the power industry. This year's exhibition has reached a record scale, with over 2,000 domestic and international companies gathering in an 86,000-square-meter exhibition area to jointly envision an innovative future for the power industry. Xi'an Xuzhihui Electromechanical Technology Co., Ltd. made a grand appearance at this exhibition with a brand-new image. Their booth, located at E03 in Hall N5, featured an exquisite layout and a rich array of exhibits, attracting numerous professional visitors. On the first day of the exhibition, the Xuzhihui booth was bustling with visitors, drawing many professionals. The company's key product series for cable fault testing became the focus of attention. Exhibited equipment included: cable fault rangefinders, cable fault locators, lever-type and trolley-type high-voltage pulse generators, high-voltage bridges, cable path meters, cable outer sheath fault locators, cable identifiers, cable puncture detectors, overhead line fault testers, cable quality analyzers, cable fault testing systems, cable fault verification devices, ultra-low frequency withstand voltage testing equipment, demagnetizers, and surge arrester monitor calibrators. These products, with their innovative design, superior performance, and user-friendly operation, won high praise from the audience, fully demonstrating the company's technical strength in the field of power testing.
Science Popularization Class: Polyvinyl Chloride Insulated Cables 2025-11-17 PVC cables are mainly used in medium and low voltage systems of 6/6, 6/10kV and below, with the largest application in 1kV distribution lines. PVC cables come in single-core, two-core, three-core, four-core, and multi-core configurations. A typical structure of a 1kV PVC power cable is shown in the figure. Most cables have a circular structure and lack a metal shielding layer. For special-purpose cables, such as some mining cables, airport lighting cables, and oilfield well cables, a single-core independent metal shield or a parallel flat structure may be used. The structure of PVC insulated cables with a rated voltage of 6kV and above can be referenced from the cross-linked polyethylene cable structure diagram. These cables are less commonly used in practice. Due to the widespread use of PVC insulated low-voltage cables in power distribution systems, regular testing and maintenance are rarely performed, resulting in a high failure rate. A significant portion of these cables operate with defects, often manifesting as high-resistance leakage faults between phases or between phases and ground, and open-circuit (broken line) faults.
