On May 27, 2026, Wrindu warmly welcomed overseas customers to visit the factory and experience a live demonstration of multiple high-voltage testing systems. The visit gave customers a closer look at Wrindu’s manufacturing process, product performance, and technical service capabilities, further strengthening confidence in the company’s solutions for the power industry.
During the factory tour, Wrindu engineers introduced a wide range of electrical testing equipment and demonstrated real testing procedures in a professional working environment. The demonstrations included:
- Series resonance withstand voltage testing
- Transformer DC resistance testing
- Transformer tan delta testing
- SF6 gas comprehensive analysis
- Circuit breaker mechanical testing
- Transformer oil dielectric strength testing
Live Demonstration of Advanced High-Voltage Testing Equipment
One of the highlights of the visit was the live operation of the RDXB(WJ)-450kW Frequency Modulation Series Resonance Test System. The system successfully performed induced voltage withstand testing and partial discharge testing for power transformers up to 400kV/350MVA. Customers observed its automatic resonant frequency tracking, stable voltage output, low waveform distortion, and multiple safety protection functions, all of which help ensure safe and reliable high-voltage testing.
Wrindu engineers also demonstrated the RD6000A Transformer Tan Delta Tester. With advanced frequency conversion anti-interference technology, the device can provide highly accurate dielectric loss measurements even in substations with strong electromagnetic interference. This helps maintenance teams improve transformer condition assessment and testing reliability.
For SF6 gas analysis, the RDZHF-709B SF6 Comprehensive Tester attracted strong customer interest. The equipment integrates dew point measurement, gas purity testing, and decomposition product analysis into one system, helping utilities improve maintenance efficiency while reducing SF6 gas consumption and operating costs.
The demonstration continued with the RDGC-8A Circuit Breaker Comprehensive Tester, which can accurately measure opening and closing time, speed, travel distance, and bounce characteristics for vacuum, GIS, SF6, and oil circuit breakers. Customers appreciated the tester’s high accuracy and user-friendly operation.
In addition, Wrindu presented the RDJJD-100kV Oil Dielectric Strength Tester. The system automatically performs insulating oil breakdown voltage testing with stable performance, strong anti-interference capability, and high testing precision, helping ensure transformer insulation reliability.
