Core Performance Breakthroughs

1. Ultra-High Electrical Insulation: The product is made of power-supply-specific modified PEEK material, with electrical insulation resistance up to 10¹⁴Ω·cm and breakdown voltage ≥35kV/mm, fully complying with IEC electrical safety standards. It effectively isolates electrical circuits, prevents leakage and short-circuit risks caused by transmission component contact, and ensures the safe operation of power supply equipment—solving the key safety hazard of traditional metal nuts being prone to electrical conduction.

2. Stable Low-Speed Load Transmission: Optimized for the low-speed continuous operation characteristics of power supply equipment (≤150 RPM), the product adopts precision thread shaping technology to achieve zero clearance fit with the screw, ensuring smooth, non-jitter transmission even under long-term low-speed load. Its low friction coefficient (0.09-0.26) reduces energy loss, avoiding transmission jamming and switching failure caused by wear—common issues in power supply transmission systems.

3. Anti-Corrosion & Anti-Dust Protection: Equipped with anti-static and anti-corrosion surface treatment, the product can resist mild corrosive media (such as electrical cleaning agents) and prevent electrical dust accumulation. This avoids material degradation and thread blockage caused by dust and corrosion, ensuring stable transmission performance in power supply cabinets and harsh outdoor power supply environments, and reducing equipment failure rate.

4. Compact & Lightweight Design: With a density of only 1.32g/cm³, the product features a compact structural design, perfectly adapting to the narrow installation space of power supply cabinets, UPS power supplies, and power transformers. Its excellent mechanical properties (tensile strength of 98-118MPa) ensure stable load-bearing capacity despite its small size, meeting the low-load, high-stability transmission needs of power supply equipment without increasing the overall weight of the device.

5. Long-Life & Low-Maintenance: The modified PEEK material has excellent wear resistance, which is 3-4 times that of ordinary PEEK materials and 4-5 times that of traditional plastic nuts. Under normal use and regular maintenance, the service life can reach 9-13 years, effectively reducing the frequency of component replacement and maintenance costs for power enterprises—addressing the pain point of frequent maintenance of power supply transmission components.
