Heavy-Duty Impulse Voltage Generator & Lightning Testing System for Power Transmission Grids, GIS & Power Cable Testing (3600kV-4800kV)

• 1. Product Overview: Built for mega-scale power transmission testing, our Heavy-Duty Impulse Voltage Generator delivers massive energy output ranging from 80 kJ to 320 kJ across ultra-high voltage tiers (3600kV to 4800kV). Engineered with robust structural stability, high-capacity stage capacitors (0.5μF to 1μF per stage), and automated earthing safety systems, it is the ultimate testing powerhouse for high-voltage cables, Gas Insulated Switchgear (GIS), and long-distance transmission line components.

• 2. Core Test Functions:

  • UHV Power Cable & GIS Testing: Simulates extreme atmospheric transient overvoltages on underground power cables and GIS sub-assemblies.

  • High-Energy Impulse Stress Testing: Delivers high energy ratings (up to 320 KJ) to test thermal and mechanical endurance limits of heavy electrical apparatus.

  • Automated Protective Earthing: Features failsafe pneumatic or electromagnetic grounding mechanisms that engage automatically when testing halts or doors open.

  • Multi-Stage Synchronization Control: Synchronized multiple sphere gap triggering ensures simultaneous firing and minimal jitter across all generator stages.

• 3. Customer Frequently Asked Questions (FAQ):

  • Q1: What are the space and ceiling height requirements for installing a 4800kV impulse system?

  • A1: High-voltage laboratories require specific clearances based on impulse voltage ratings. Our engineering team provides custom layout design blueprints and safety clearance calculations tailored to your building dimensions.

  • Q2: What maintenance is required for the sphere gaps and capacitor banks?

  • A2: Regular inspection and cleaning of the sphere gaps to prevent pitting, along with periodic calibration of the divider resistors and voltage meters, ensure long-term operational precision.
