The company's leading products are tires, covering more than 3,000 specifications and varieties such as high-performance passenger car radial tires, passenger and light truck radial tires, and all-steel truck radial tires, with an annual production capacity of up to 35 million units.
The internal mixers, as the loads in the system, feature rapid load changes and contain a large number of harmonic components. Therefore, power quality measurement and analysis are carried out to provide customers with safe, effective and economical solutions.

The recommended solution is to install NCSTD Tuned Filters to achieve rapid compensation, significantly mitigate the voltage drop issue during the operation of internal mixers, and improve power supply quality.
Quantity: 2 sets
Fast switching response, specifically designed for rapidly varying loads
Switching response time: 20 ms
Protection class: IP20
