As requested, specific embodiment of the present utility model will be disclosed here.It is to be understood, however, that institute here
The embodiment of disclosure is only exemplary of the present utility model, and it can be presented as various forms.Therefore, disclose here
Detail be not to be considered as limiting, and be merely possible to claim basis and as be used for instruct this area
Technical staff by practice it is any it is appropriate in a manner of differently apply representational basis of the present utility model, including using here
The feature that disclosed various features and combination may not disclosed clearly here.
Embodiment one：
It is the power transmission rod 1000 of the present embodiment as shown in Figure 1, the power transmission rod 1000 includes cross-arm 100 and the body of rod 10, cross-arm
100 are fixed on the body of rod 10 by fixing device 11.Fixing device 11 includes cross-arm accommodating member 110, connecting plate 120 and the body of rod and connected
Fitting 12, cross-arm accommodating member 110 are used to house cross-arm 100, and connecting plate 120 is used to be fixedly connected with cross-arm 100 and cross-arm accommodating member
110, body of rod connector 12 is used for be connected connecting plate 120 and the body of rod 10.
Referring to Fig. 1 and Fig. 2, in the present embodiment, cross-arm 100 is compound cross-arm, including plug 101, insulating barrier 102 and is held
Power part 103, insulating barrier 102 and bearing member 103 are coated and fixed on the outer peripheral face of plug 101, and bearing member 103 is located at plug 101
The middle part being connected with the body of rod 10, insulating barrier 102 is positioned at other regions in addition to middle part.Certainly, the utility model is also not limited to
This, cross-arm 100 can also use the metal cross arms such as traditional iron cross arm, steel cross-arm.
Specifically, in the present embodiment, plug 101 is the main composition important document of compound cross-arm 100, it is necessary to there is enough branch
Intensity is held, typically by pultrusion after glass fibre and resin mixing, it is of course also possible to after by glass fibre and resin mixing
Compression molding, or other technological formings are used, this is not limited.The optional polyurethane of resin, epoxy resin or vinyl tree
Fat etc..
Plug 101 can be solid, or at least have the body of a chamber, and the cross sectional shape of plug 101 is optional
Circular, polygon or I-shaped, can be selected as needed in practical engineering application.The plug 101 of the present embodiment is solid
Rectangular configuration.
Plug 101 is chronically exposed in air, easily by the corrosion of various natural causes such as light, electricity, water, acid etc., is made
Phenomena such as intensity decreases being produced into surface aging, therefore usually require to handle the surface of plug 101, conventional way is
In the Surface coating fixed insulation layer 102 of plug 101, the insulating properties of plug 101 can be further provided for and play corrosion-resisting function.
Insulating barrier 102 is chosen as full skirt 1021 and the sheath 1022 extended on plug 101, or is directly to be coated on core
The sheath 1022 on the surface of rod 101, full skirt 1021 or sheath 1022 can use the silicon rubber of molding sulfidization molding to be made, or adopt
It is made of the silicon rubber of integral injection molding, the insulating barrier 102 has good hydrophobicity and ageing resistance, service life height.
But the insulating barrier 102 does not have the ability of bearing load, if load is acted directly on insulating barrier 102, easily cause absolutely
The cracking of edge layer 102 or come off, so that plug 101 exposes in atmosphere, intensity decreases, mechanical properties decrease.
Therefore, the compound cross-arm 100 of the present embodiment, a bearing member is preset at the position that plug 101 is connected with the body of rod 10
103, the bearing member 103 be usually metal bearing member 103, be also not excluded for certainly using the material that other have sufficient intensity as
