Embodiment
Below in conjunction with accompanying drawing and a specific embodiment, describe.
Referring to Fig. 1 to Fig. 5.The described a kind of porcelain pole arm insulation barrier of the present embodiment, comprise the first insulation barrier 11a and the second insulation barrier 11b, and body, the material of the first insulation barrier 11a and the second insulation barrier 11b are identical.The first insulation barrier 11a and the second insulation barrier 11b are the rectangular slab of the glass steel material that insulation property are good.Fiberglass is to make the reinforced plastics of reinforcing material with glass fibre or its goods, or is fiberglass reinforced plastics, is a kind of common materials of the prior art.The present invention selects light weight and hard, and non-conductive, mechanical strength is high, corrosion resistant fiberglass.The thickness of fiberglass has a certain impact to insulation property, as indicative ground, the invention provides a fiberglass gauge, is 3.2mm.
Two long edge joints of the first insulation barrier 11a and the second insulation barrier 11b close or form an insulation barrier of the rectangle with centre bore while fitting together.As a kind of embodiment, be provided with slot on the composition surface of the first insulation barrier 11a, be provided with cutting on the composition surface of described the second insulation barrier 11b, the first insulation barrier 11a and the second insulation barrier 11b are by socket connection.Certainly, also slot or cutting can be set on the first insulation barrier 11a and the second insulation barrier 11b.Be provided with the first insulation sight shield 12a and the first semicircle breach on the jointing edge of the first insulation barrier 11a, be provided with the second insulation sight shield 12b and the second semicircle breach on the jointing edge of the second insulation barrier 11b.Be equiped with the first semi-ring cushion 21a on the first semicircle breach, be equiped with the second semi-circular cushion 21b on the second semicircle breach, on centre bore, be equiped with annular soft pad, the material of this annular soft pad is silicon rubber.During use, porcelain pole arm is stuck in centre bore, silicon rubber cushion and porcelain pole arm fit tightly, and do not stay gap, and make insulation barrier not loosening, not positioning in the porcelain pole arm installation place.The section of this cushion is herringbone, and its upper end is provided with for blocking the groove of the first insulation barrier 11a or the second insulation barrier 11b.As indicative ground, the thickness of cushion is 3mm.
