MEASURES FOR PROLONGING BUSHING LIFE

Measures for prolonging bushing life in actual production,such as the adjustment for bushing temperature difference and bushing deformation,the cleaning of dirt on the bushing support,the replacement of copper clamps and the handling for too big voltage drop between the bushing terminals and copper clamps,are introduced.By these means,the bushing life is prolonged by one tenth cycle in average,resulting in a significant increase of economic benifits.
