GDZX Unveils ZXBXZ Series: Revolutionizing AC Withstand Voltage Testing for Global Substations

Wuhan, China — July 24, 2025 — GDZX Power Equipment Co., Ltd. ("GDZX"), a leading innovator in high-voltage testing solutions based in Wuhan, China, proudly announces the global launch of its flagship ZXBXZ Series AC Withstand Voltage Resonant Test System. Engineered to meet IEC and international safety standards, this cutting-edge system sets a new benchmark for reliability and efficiency in substation electrical testing worldwide.

Unmatched Technical Excellence

The ZXBXZ Series leverages advanced series resonance technology to deliver precise high-voltage AC testing for critical substation equipment up to 500kV, including transformers, GIS systems, cables, circuit breakers, and insulators. Key innovations include:

• Pure Sine Wave Output (<1.0% distortion) across 30–300Hz frequency range, ensuring compliance with IEEE and CIGRE testing protocols.

• Dual Auto/Manual Modes: Automatically locates resonance points and adjusts voltage, or allows full manual control for complex scenarios.
• Configurable Reactors: Dry epoxy-cast reactors (25–200kV) support series/parallel combinations, enabling flexible adaptation to test objects from 10kV to 500kV.
• Smart Grid Compatibility: Real-time voltage stabilization against grid fluctuations, powered by universal 220V/380V input.

  Global Applications, Localized Solutions

  Designed for field and lab versatility, the ZXBXZ Series offers preconfigured systems for diverse global substation needs:

  Model	Max Voltage	Key Applications
  ZXBXZ-200/200/50	200kV	110kV transformers, GIS, 35kV cables ≤1.0km1
  ZXBXZ-800/400/50	400kV	220kV transformers, 110kV cables ≤0.7km4
  ZXBXZ-1600/800/200	800kV	500kV GIS, 220kV cables ≤1.0km6
  Customizable configurations available for specialized projects.
