Frequently Asked Questions
Is 1000V an AC RMS (alternating current root mean square) or DC (direct current) voltage?
This 1000V rating refers to the peak voltage withstand rating. Whether it refers to AC RMS or DC needs to be confirmed according to the detailed product specifications. Typically, the DC withstand voltage test value for such high-voltage slip rings is higher.
Why is silicone wire used instead of common Teflon wire?
AWG20# silicone wire exhibits excellent performance in terms of high voltage resistance, flexibility, and extreme temperature range (typically -60℃ to +200℃). It also has excellent arc resistance and aging resistance, making it particularly suitable for harsh environments with high voltage and potential thermal shock, thus providing higher safety.
How is long-term safety ensured for high-voltage connections at a rotational speed of 250 RPM?
The product uses precious metal contacts to reduce electrical sparks, an optimized insulation structure and dynamic sealing design to prevent carbon dust accumulation, and rigorous dynamic balancing tests to ensure smooth operation at high speeds. These measures collectively ensure long-term insulation safety and electrical stability of the high-voltage connection at high rotational speeds.
