Abstract
Discloses is a composite bracket insulator for a subway. The insulator has an integral structure, and comprises a solid rod at the middle part, connecting steel caps at two ends and big umbrella skirts; and crimping connections are provided between the solid rod and the steel caps, and an outer part of the solid rod are wrapped with silicone rubber to form the three big umbrella skirts. The composite bracket insulator has the advantages of good mechanical strength, good electrical performance and good breaking strength; the umbrella skirts employs open type big umbrellas, and the composite bracket insulator also has the advantages of good anti-pollution performance, the increased creepage distance, the high pollution class, high voltage resistance and the good dustproof effect; and the composite bracket insulator can be widely applied to subway and city light rail lines.

The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of high performance subway composite wrist-arm insulator.
The technical solution of the utility model is: a kind of subway composite wrist-arm insulator, described insulator is as a whole, it comprises the connection steel cap at middle solid bar, two ends, large full skirt, and wherein solid bar and the crimping of steel cap, is rolled into three large full skirts in solid bar outside with silicon rubber.
Described insulator height is 343mm, and the diameter of solid bar is 80mm, and the external diameter of the steel cap at two ends is 92mm, and the internal diameter of steel cap is 80mm, and the diameter of large cluster parachute is 200mm.
Described steel cap is divided into upper end connection steel cap and is connected steel cap with lower end, wherein upper end connects steel cap and is divided into two-stage structure, with solid bar crimping be the cylinder hollow cylinder of internal diameter 80mm, degree of depth 35mm, what be connected with joint outer part is the cylinder hollow cylinder of internal diameter 62mm, degree of depth 85mm; It is the cylinder hollow cylinder of an internal diameter 80mm, degree of depth 35mm that lower end connects steel cap.
On described cylinder hollow cylinder, all have a flat cuboid, cuboid is provided with the circular mounting hole that a diameter is 22mm.
The utility model has the advantages that: the utlity model has good mechanical strength, electric property and breakdown strength, full skirt adopts open gamp, anti-pollution characteristic is good, and creepage distance increases, and gradation for surface pollution is high, high pressure resistant, good dustproof effect, can be widely used in subway and urban light rail route.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As shown in Figure 1, a kind of subway composite wrist-arm insulator, described insulator is as a whole, and it comprises the connection steel cap at middle solid bar 1, two ends, large full skirt 3, wherein solid bar 1 and the crimping of steel cap, be rolled into three large full skirts 3 in solid bar 1 outside with silicon rubber.Insulator height overall is 343mm, and the diameter of solid bar 1 is 80mm, and the external diameter of the steel cap at two ends is 92mm, and the internal diameter of steel cap is 80mm, and the diameter of large cluster parachute 3 is 200mm.
Steel cap is divided into upper end connection steel cap 2.1 and is connected steel cap 2.2 with lower end, wherein upper end connects steel cap 2.1 and is divided into two-stage structure, with solid bar 1 crimping be the cylinder hollow cylinder of internal diameter 80mm, degree of depth 35mm, what be connected with joint outer part is the cylinder hollow cylinder of internal diameter 62mm, degree of depth 85mm; It is the cylinder hollow cylinder of an internal diameter 80mm, degree of depth 35mm that lower end connects steel cap 2.2.On cylinder hollow cylinder, all have a flat cuboid, cuboid is provided with the circular mounting hole that a diameter is 22mm.
Such composite insulator for subway has good mechanical strength, electric property and breakdown strength, and full skirt adopts open gamp, anti-pollution characteristic is good, and creepage distance increases, and gradation for surface pollution is high, high pressure resistant, good dustproof effect, can be widely used in subway and urban light rail route.
