High voltage-withstanding bus duct for wind power/nuclear power/hydroelectric power

The utility model discloses a high voltage-withstanding bus duct for wind power/nuclear power/hydroelectric power, which comprises a shell, current-carrying conductors and insulating material, wherein the shell is made of composite resin. Since the linear expansion coefficient of the composite resin is close to that of the conductor, the circumstance of mutual 'extensional occlusion' cannot occur in the bus duct after the materials with different expansion coefficients are assembled together, consequently, the insulating protection of the bus duct is enhanced, the insulating property is extremely high, the safety of the bus duct is enhanced, in particular, the safety of the bus duct is guaranteed when operating under high voltage, and the bus duct can withstand 35KV of high voltage. Meanwhile, since the composite resin has high water-resisting and corrosion-resisting properties, the bus duct cannot be corroded after operating under the water for a long time, consequently, the current-carrying conductors in th
