摘要： An electric multiple unit car-roof antifouling flash composite insulator comprising a support body (21) and several sets of sheds (22) provided around the sidewall of the support body (21) and arranged in parallel in the axial direction. The sheds (22) protrude in the radial direction from the sidewall of the support body (21). An upper metal fitting (23) is arranged at the upper extremity of the uppermost shed (22). A lower metal fitting (24) is arranged at the lower extremity of the lowermost shed (22). The creepage distance of the sheds between the upper fitting (23) and the lower fitting (24) is 1085 mm to 1095 mm. The arc-flash distance between the upper metal fitting (23) and the lower metal fitting (24) is 245 mm to 255 mm. The insulator employs a long creepage distance in terms of structural design, thus providing great antifouling flash capability, under same pollution conditions, provides great antifouling flash capability that is twice as great as that of a ceramic insulator having a same creepage distance, and is particularly suitable for use in areas having above-average pollutions.

摘要： An interface breakdown-proof locomotive roof composite insulator. The composite insulator comprises: a support body; and at least five shed groups arranged side by side along the axial direction that are provided around the sidewall of the support body, the at least five shed groups includes: at least four shed groups located on the upper end with each group including a large shed and a small shed; and at least one shed group located on the undermost end with each group including two small sheds. For such a shed structure, it is favorable to tolerate impulse voltage, and it is difficult for the interface to be broken down; the electric field on the interface even does not exceed 3kV/mm, and even if a gas exists on the interface, it will not break through the interface.
