Embodiment Construction

[0010] Now in conjunction with accompanying drawing, the present invention is further described.

[0011] Such as figure 1 As shown, a composite arm insulator for subway, the insulator is a whole, it includes a solid rod 1 in the middle, connecting steel caps at both ends, and a large umbrella skirt 3, wherein the solid rod 1 is crimped with the steel cap, and the solid rod 1 is crimped with the steel cap. The outside of the rod 1 is wrapped with silicon rubber to form three large umbrella skirts 3 . The total height of the insulator is 343mm, the diameter of the solid rod 1 is 80mm, the outer diameter of the steel caps at both ends is 92mm, the inner diameter of the steel cap is 80mm, and the diameter of the large umbrella group 3 is 200mm.

[0012] The steel cap is divided into the upper end connection steel cap 2.1 and the lower end connection steel cap 2.2, wherein the upper end connection steel cap 2.1 is divided into two sections of structure, and the cylindrical hollow...

Abstract

The invention relates to a composite bracket insulator for metros. The composite bracket insulator is integrated and comprises a solid bar positioned in the middle, connection steel caps positioned at two ends, and large umbrella shirts, wherein the solid bar is in pressing connection with the steel caps, and silicone rubbers wrap the solid bar to form three large umbrella shirts. The composite bracket insulator for the metros is good in mechanical strength, electrical performance and damage strength, good in fouling resistance by means of large open umbrellas of the umbrella skirts, large in creepage distance, high in pollution grade, resistant to high pressure, good in dustproof performance and capable of being widely applied to the metros and urban light rail lines.

Description

technical field [0001] The invention relates to the field of composite electrical materials, in particular to a composite arm insulator for subways. Background technique [0002] At present, most of the insulators used in subways use ceramic insulators. The processing technology of ceramic insulators is complicated, the processing process is very difficult to control, the quality is also difficult to grasp, the mechanical strength is low, easy to break, and the electrical performance is unstable. Contents of the invention [0003] In view of the deficiencies in the prior art above, the purpose of the present invention is to provide a high-performance composite arm insulator for subways. [0004] The technical solution of the present invention is: a composite arm insulator for subway, the insulator is a whole, it includes a solid rod in the middle, connecting steel caps at both ends, and a large shed, wherein the solid rod and the steel cap are crimped, The outside of t...
