Product Overview

Core Product Competitive Advantages

1. Dual AC & DC High-Voltage Output Channels
   Dual-mode high voltage transformer unit delivers AC 0~50kV and DC 0~70kV adjustable output under a 10KVA rated capacity, covering all common power-frequency and DC dielectric test schemes for insulation films, thick plastic slabs and rigid ceramic parts. Independent voltage regulation circuit eliminates cross-interference between AC and DC test modes.
2. Two Optional Automatic Boosting Modes
   Operators freely switch linear uniform voltage rise or segmented ladder boosting programs on the control PC, with adjustable ramp speed ranging from 5V/s to 5000V/s to match different standard test requirements. Once breakdown is detected, the system instantly cuts high voltage and resets the regulator back to zero to avoid secondary ablation of sample surfaces.
3. Stainless Steel Standard Electrode Assembly
   Upper and lower test electrodes adopt polished stainless steel with uniform 25mm diameter and height, ensuring consistent contact pressure and uniform electric field distribution on specimen surfaces. Insulated support stand isolates electrodes from the cabinet base to eliminate stray current interference and improve measurement repeatability.
4. PC Intelligent Data Acquisition & Analysis System
   Dedicated test software synchronously records voltage, leakage current and time curves throughout the whole test cycle, automatically computing dielectric strength after breakdown. All test batches can be saved locally, recalled for comparative analysis, and exported as editable PDF/Excel inspection reports with one-click printing function.
5. Multi-Layer Comprehensive Safety Protection System

• Cabinet door interlock: High voltage output is automatically disabled once the observation window is opened
• Overcurrent & leakage real-time monitoring: Power cuts off immediately when abnormal current surge occurs
• Zero-voltage startup protection: Equipment only allows high-voltage boosting after voltage regulator fully resets
• Built-in ground leakage protection circuit to shield operators from electric shock hazards

6. Mobile Integrated Cabinet Layout
   Whole machine mounted on silent universal casters with adjustable leveling feet, easy to relocate between different lab test zones. Enclosed full observation window blocks high-voltage arc splashes, cabinet shell adopts anti-rust electrostatic baking coating for long-term anti-corrosion service in humid laboratory environments.

Standard Complete Test Operation Flow

1. Equipment Inspection & Parameter Setup
   Check tightness of ground wire and cabinet door interlock function, launch dedicated test software on the control PC, select AC/DC test mode and customize boosting speed, withstand holding time according material standards.
3. Specimen Placement & Electrode Alignment
   Cut insulating material into standard flat specimens, place evenly between upper and lower stainless electrodes, ensure no bubbles or foreign particles exist on contact surfaces to avoid premature breakdown interference.
4. Safety Cabinet Sealing
   Close the double transparent observation door completely; the system will lock high-voltage output permission only after detecting fully closed interlock signal.
5. Automatic High-Voltage Boosting Test
   Click start program; the equipment steadily raises voltage following preset speed, continuously recording real-time voltage and leakage current data and drawing real-time characteristic curves on screen.
6. Breakdown Capture & Data Calculation
   When dielectric breakdown occurs, the system instantly cuts high voltage and auto-resets regulator to zero, locking critical breakdown voltage value and automatically calculating material dielectric strength index.
7. Data Storage & Post-Test Cleaning
   Save single or batch test records, generate and print formal inspection reports; open cabinet door to take out broken specimens, wipe electrode surfaces clean and cut off main power supply after daily testing.

Execute full compliance testing per ASTM D149 and IEC 60243, issue internationally recognized inspection reports for product market access and factory batch acceptance.
