Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment 1
With reference to figure 1, a kind of windage yaw preventing composite insulator, it includes insulator main body and wire fitting.
Described insulator main body mainly is made of plug 1, silicon rubber full skirt cover 2, upper end gold utensil 3 and lower end gold utensil 4.
Upper end gold utensil 3 has upper cannula portion 31 and shaft tower connecting portion 32, and shaft tower connecting portion 32 arranges that for the T font it has 2 bolts hole with upper cannula portion 31, and upper end gold utensil 3 fixedly is placed in an end of plug 1 by upper cannula portion 31.
Lower end gold utensil 4 has setting of casing section 41 and wire clamp connecting portion 42, and lower end gold utensil 4 fixedly is placed in the other end of plug 1 by setting of casing section 41.
Outside the plug 1 that silicon rubber full skirt cover 2 is wrapped between upper end gold utensil 3 and the lower end gold utensil 4, its two ends are tightly connected with upper cannula portion 31 ends and setting of casing section 41 ends respectively.
The wire clamp connecting portion 42 of lower end gold utensil 4 has 2 bolts hole and by bolt the wire fitting is installed, described wire fitting is tabular wire clamp 5, the bolt hole of tabular wire clamp 5 corresponding lower end gold utensils 4 has perforation, tabular wire clamp 5 has been horizontally set with wire casing 50 near the middle part, a side of lower end gold utensils 4, the bolt hole that bolt 51 passes lower end gold utensil 4 be connected the perforation of wire clamp 5 the insulator main body be connected with the wire fitting.
When using the windage yaw preventing composite insulator of present embodiment, the shaft tower connecting portion 32 of upper end gold utensil 3 is connected on the cross-arm 7 by cross-arm 7 belows of bolt by shaft tower, wire is preset in the wire casing 50 of tabular wire clamp 5, the wire clamp connecting portion 42 of tabular wire clamp 5 and lower end gold utensil 4 also is fixedly connected with by bolt 51, make the wire clamp connecting portion 42 of lower end gold utensil 4 and tabular wire clamp 5 with the conductor clamping in the wire casing 50, finish installation.The characteristics that the windage yaw preventing composite insulator of present embodiment has is simple in structure, be easy to install, production cost is low.
