An Environmental-Friendly Al-Cu Alloy Material for Electric Power Grounding Grid

Abstract:

Galvanized steel, a general grounding material, has a short service life due to high corrosion rate in alkaline soil environment. An Al-4.5Cu-Re alloy was developed to overcome the shortcoming of galvanized steel. The properties of Al-4.5Cu-Re alloy were studied by accelerated corrosion test, grounding resistance test, electrochemical test and comprehensive electrical performance test in alkaline soil. The results show that the Al-Cu alloy with shot blasting and pre-oxidation exhibited low grounding resistance, high corrosion resistance, good comprehensive electrical performance and environment friendly feature. Al-Cu alloy with shot blasting and pre-oxidation can be used as grounding material.
