Connection；
It includes core that the pillar, which can trample composite insulator, and silicon rubber umbrella skirt is equipped at intervals on the core and can be trampled
Full skirt；
The two sides of the hanging wire fitting be separately connected first press shading ring, the both ends of the suspended compound insulator and
The both ends that pillar can trample composite insulator respectively connect second and press shading ring.
One end that the suspended compound insulator is not connect with hanging wire fitting is also connect with adjustable length structure fitting, is used
It is connect in shaft tower, is easily installed cooperation.
The pillar can trample one end that composite insulator is not connect with hanging wire fitting and also connect with connection gold utensil, for
Shaft tower connection.
It is described that trample full skirt to include but is not limited to be aliphatic epoxy resin or PE modified material.
The beveled structure for trampling full skirt is including but not limited to rectangular, round or ellipse.
The silicon rubber umbrella skirt and the length that can trample full skirt are respectively 30-60cm.Meet adult's stride length rule,
Full skirt can be trampled by trampling conducive to operation maintenance personnel.
The core uses glass fiber reinforced epoxy resin based composites.
The utility model has the beneficial effects that
The advantages of there is the utility model mechanics to carry, easy to connect, and thunder-lightning punctures.
Shaft tower height and width of corridor are reduced, full skirt can trample later period operation and maintenance conveniently, and core voidage is low, electricity
Performance is high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1. pillars can trample composite insulator；2. silicon rubber umbrella skirt；3. full skirt can be trampled；4. the first pressure shielding
Ring；5. suspended compound insulator；6. adjustable length structure fitting, 7. second press shading ring.
Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
Traditional steel construction cross-arm adds the form of suspension insulator, and there are windage yaw accidents, while the form increases whole tower
High and width of corridor；
Most of pillar composite insulation cross arm uses internal composite material core, outer general injection or suit silicon rubber at this stage
The structure type of glue full skirt.The characteristics of silicon rubber is soft material, can not be trampled seriously constrains the operation and maintenance in later period；
Hard full skirt has no prolonged application operating experience, can not be complete under natural conditions and extreme high voltage band electro ultrafiltration
By.
In view of the above problems, the utility model, which provides a kind of extra-high voltage, can trample O&M composite insulation cross arm, steel knot is substituted
Structure cross-arm adds the form of suspension insulator, and so as to reduce transmission tower tower head windage yaw discharge fault, it is wide to reduce corridor
Degree and shaft tower height have ensured the safe and reliable operation of transmission of electricity cable.
As shown in Figure 1, extra-high voltage can trample O&M composite insulation cross arm, including two 5 Hes of pull rod suspended compound insulator
Two compression bar pillars can trample composite insulator 1, and all suspended compound insulators and pillar can trample the one of composite insulator
End is all connect with hanging wire fitting；In the utility model two pull rods, two compression bars by a hanging wire fitting be connected as one it is whole
Body.
It includes core that the pillar, which can trample composite insulator, and silicon rubber umbrella skirt 2 is equipped at intervals on the core and can be stepped on
Step on full skirt 3；
The two sides of the hanging wire fitting are separately connected one first and press shading ring 4, and first presses the size of 4 ring of shading ring
Need to guarantee the area of ring hanging wire fitting packet inside, the both ends of the suspended compound insulator and pillar can trample compound
