Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of 10kV distributions uninterrupted operation fixed power source lead wire insulation cross-arm, bag
Include flat cross-arm 1, side phase terminal fixing device 2, middle phase terminal fixing device 3, vertical hack lever 4, rubber washer 5, front rail
6th, fixed hook 7, the flat both sides of cross-arm 1, which are integrally formed, is provided with vertical hack lever 4, and the vertical upper and lower side of hack lever 4 is set with rubber blanket
Circle 5, side phase terminal fixing device 2 is sleeved on the flat both sides of cross-arm 1, and the two side ends of side phase terminal fixing device 2 are welded with horizontal column
Bar 6, the bottom of side phase terminal fixing device 2 are welded with fixed hook 7, and the flat centre position of cross-arm 1 is welded with middle phase terminal and fixed
Device 3.
The flat cross-arm 1 selects epoxy resin fiberglass enhanced type composite material.
The inside of flat cross-arm 1 point filling insulating foams reduce deadweight, and the inside and outside each aspect of cross-arm is carried out with insulated paint
Coating protection.
The side phase terminal fixing device 2 is fixedly mounted using horizontal.
Utility model works principle：Insulator crossarm aid installation process step is few, easy to operate, and three phase terminals can
It is also secured on a secondary cross-arm, insulation safety performance easy to carry is high, and operating personnel only need to be in wire lower work, without wearing
More between the two phases, cost is not high, required main material epoxy resin board；When installation cross-arm uses coupling type, operation vehicle only needs
It can be installed in live wire vertical lower, step is few, simple to operate, and it is convenient that job position is chosen, and during more exchange device, has removed
