HARDWARE FOR POWER TRANSMISSION AND DISTRIBUTION EQUIPMENT, STRINGING HARDWARE FOR POWER TRANSMISSION AND DISTRIBUTION AND OUTDOOR EQUIPMENT FOR POWER SUPPLY STATION

摘要

PURPOSE:To develop a high-strength material resistant to salt and acid and appropriate as the material for the hardware for the power transmission and distribution equipment, the stringing hardware for the power transmission and distribution and the outdoor equipment for a power supply station by forming a Zn-Al alloy layer on the surface of an iron-based metallic material. CONSTITUTION:The electrical equipment in the transformer station, power supply station, etc., is susceptible to gaseous SO2 and acid rain and does not withstand long-time use. Accordingly, the hardware for power transmission and distribution equipment, the stringing hardware for power transmission and distribution and the outdoor electrical equipment are produced from an iron-based metallic material, and the material is dipped in a molten Zn-Al alloy contg. about 5-10wt.% Al to form a Zn-Al alloy layer having 40-150mum average thickness on the surface. The electrical part having excellent resistance to salt and acid and high strength and having a longer service life than the conventional galvanized part is obtained.
