    Abstract: This paper simulated and calculated the discharge silicone rubber bushing to improve the insulation capacity. It studied the influence of the ground shield on the center conductor of the silicon isolator and the surface electric field of the umbrella group. It optimized and improved the ground shield of the silicone rubber bushing in terms of size and shape.The surface electric field margin has been promoted by using the improved center conductor of the silicone rubber bushing. This research carries out the insulation test of the improved silicone rubber bushing and verifies that the insulation performance meets the requirements.
    Key words: silicone rubber bushing; insulation capacity; optimization and improvement; insulation test
