Why do you need to replace the tower crane wire rope with a new one when it encounters high voltage?

The steel wire rope is conductive. When the steel wire rope conducts electricity, it will generate heat. If the temperature of the steel wire exceeds 200 degrees, the metallographic structure of the steel wire will change, reducing the strength and breaking tension of the steel wire rope. If it reaches 200 degrees, the wire rope grease will generally burn. If the wire rope grease is normal. It is estimated that the strength of the steel wire rope will not change. In addition, the manganese-based phosphate-coated steel wire rope has been treated with manganese-based phosphating. The steel wire is wear-resistant, corrosion-resistant and has increased resistance. The service life of the steel wire rope is greatly improved compared with the smooth steel wire rope of the same structure. . For reference only
