Abstract
The utility model relates to a wire insulation and supporting device on a single-loop overhead line, in particular to a casing insulator for a concrete pole on an overhead line. The casing insulator comprises a frustum-shaped insulation device, wherein a U-shaped groove is formed on the top of the insulation device; and a fixed aluminum plate is fixed above the groove through bolts. The casing insulator has the advantages that the structure is simple; the insulation device is frustum-shaped, and the insulation device is matched with the top of the concrete pole, so that the insulation device can be directly and conveniently sleeved on the top of the telegraph pole during assembly.
Description
Technical field
The utility model relates to wire insulation and the bracing or strutting arrangement that uses on single time overhead transmission line, and a kind of specifically overhead transmission line cement pole is used the bushing type insulator.
Background technology
At present when the mesolow list returns the overhead transmission line design and construction; Middle phase conductor generally is fixed on masthead; Fixture generally is made up of anchor ear, strutting piece, porcelain insulator; There is following shortcoming ironware processing time consuming effort in time in use, ironware, the installation of porcelain insulator masthead is wasted time and energy, in use owing to Exposure to Sunlight, rainwater factor strutting piece can get rusty even come off.
Summary of the invention
To above deficiency, the utility model provides a kind of installation simple in structure, with low cost easy, guarantees that the overhead transmission line cement pole of the normal operation of circuit is used the bushing type insulator.
For achieving the above object, the technical scheme of the utility model is: a kind of overhead transmission line cement pole is used the bushing type insulator, comprises seal, and described seal top is provided with groove, and fixedly aluminium sheet is through being bolted to the groove top.
Described seal is taper type, and described groove is " U " type.
The beneficial effect of the utility model is: simple in structure, seal is frustum, conforms to electric pole top size, directly seal is enclosed within the electric pole top when mounted and gets final product, and is easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of the utility model.
Fixing aluminium sheet 4 bolts of 1 seal, 2 grooves 3 among the figure.
Embodiment
Further specify a kind of overhead transmission line cement pole according to accompanying drawing and use the bushing type insulator, comprise seal 1, described seal 1 top is provided with groove 2, and fixedly aluminium sheet 3 is fixed on groove 2 tops through bolt 4.Described seal is taper type, and described groove 2 is " U " type.
In use, seal is enclosed within the electric pole top gets final product, easy for installation.
Claims (2)
1. an overhead transmission line cement pole is used the bushing type insulator, comprises seal (1), it is characterized in that: described seal (1) top is provided with groove (2), and fixedly aluminium sheet (3) is fixed on groove (2) top through bolt (4).
2. use the bushing type insulator according to the said a kind of overhead transmission line cement pole of claim 1, it is characterized in that: described seal is taper type, and described groove (2) is " U " type.
