The utility model content:
The purpose of this utility model is that a kind of synthetic insulator with the design of aerodynamics umbrella shape is provided at the deficiencies in the prior art, and it has higher antifouling property.
For achieving the above object, the utility model adopts following technical scheme: it comprises ball-and-socket gold utensil, bulb gold utensil and is used to connect the acidproof plug of ball-and-socket gold utensil, bulb gold utensil; Acidproof mandrel outer is enclosed with silicon rubber; Silicon rubber is umbrella shape; Silicon rubber is arranged with the sequence interval of " gamp, two umbellules ", and the umbrella spacing of homotype umbrella and the ratio of umbrella outreach are more than or equal to 1, and the difference of the outreach of gamp and umbellule is more than or equal to 15mm.
The upper surface inclination angle of each umbrella of described silicon rubber is less than or equal to 2 ° more than or equal to 5 °, lower surface inclination angle, and this can increase the self-cleaning of synthetic insulator greatly.
The edge thickness of each umbrella of described silicon rubber is less than or equal to 12mm more than or equal to 4mm, root thickness, can guarantee once success of vulcanization process when producing.
Described silicon rubber wraps up the thickness of acidproof plug more than or equal to 5mm, and this can protect acidproof plug effectively.
After the utility model adopts said structure, because the difference that gamp and umbellule took up space increases greatly, be that airspace increases greatly, add the inclination angle of each umbrella and the restriction of umbrella spacing, the self-cleaning ability of synthetic insulator is strengthened greatly, simultaneously can avoid rainwater or the bridge joint of sleet between each umbrella, anti-pollution flashover characteristic also strengthens.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
