High -tension bushing and cable termination with uniform electric field function

The utility model discloses a high -tension bushing who has the uniform electric field function, the inside tube hole that uses of high -tension bushing is as the center pin around being provided withthe shielding net, high -tension bushing's longitudinal profile's outside edge in be close to shielding net department from down up gradually inside the extension form continuous curve or the straight line of smoothness, high -tension bushing uses on the plane that to be the inner wall that uses its tube hole enclose with high -tension bushing's the outside edge tube hole to surround the materialthat the forms sleeve pipe as solid dielectric insulation as the center pin, curve or straight line can effectively reduce the voltage gradient on solid dielectric insulation surface, play the effectthat reduces solid dielectric insulation surface electric field. 本实用新型公开种具有均匀电场功能的高压套管，高压套管内部以管孔为中心轴环绕设置有屏蔽网，高压套管的纵向剖面的外侧边缘于靠近屏蔽网处从下往上逐渐向内延伸形成平滑连续的曲线或直线，高压套管是以其管孔的内壁与高压套管的外侧边缘围成的平面以管孔为中心轴环绕形成的材料为固体绝缘介质的套管，曲线或直线能够有效降低固体绝缘介质表面的电
