Features
Material and Process: The hardware is manufactured using hot-dip galvanized steel, with the zinc coating thickness strictly meeting the standard of ≥85 μm. Through die-forging and heat treatment processes, the material achieves excellent mechanical properties and maintains good toughness even at low temperatures of -40℃. Surface sandblasting and passivation treatments further enhance corrosion resistance, meeting the long-term usage requirements in C4-level corrosive environments.
Mechanical Performance: The hardware's grip strength ranges from 45 to 187 kN, designed with a safety factor of 2.5. Finite element analysis optimizes structural stress distribution, and fatigue life testing meets the requirement of 10^7 vibration cycles. Resonance frequencies are controlled outside the system’s operational range, ensuring strength reserves to withstand sudden impact loads.
Electrical Performance: The hardware design fully considers electrothermal coupling effects, optimizing the structure to reduce eddy current losses. Electromagnetic force calculations under short-circuit conditions comply with system stability requirements, with contact resistance values controlled below 50 μΩ. Anti-corona design ensures that no partial discharge phenomena occur in high-voltage environments.
Environmental Adaptability: The hardware passes 3,000 hours of salt spray testing and 2,000 hours of ultraviolet aging tests, maintaining stable performance during temperature cycling from -40℃ to 60℃. Under humid and hot conditions, insulation resistance remains above 10^4 MΩ. Enhanced anti-corrosion coating solutions are available for special regions.
