Pass through technique scheme, when lightning protection pillar insulator is installed on support on utility poles, can first adjust the direction of unwrapping wire groove, unwrapping wire fluted shaft line direction and electric wire arragement direction are overlapped, then use monkey wrench to be stuck in prevent revolving in plane, prevent owing to turning the fixing post insulator period of the day from 11 p.m. to 1 a.m of nut owing to location and retaining part do not cause insulator body to be rotated preferably, fluted shaft line direction, direction and electric wire arragement direction are not overlapped, makes the electric wire after installation can not obtain good supporting role.
Preferably, upper end, described installation portion is provided with circular convex ring, prevents that revolving plane is arranged on circular convex ring.
Pass through technique scheme, it is possible to avoid affecting the intensity at this place of insulator body owing to the anti-setting revolving plane causes the thickness at this place of insulator body to reduce.
Preferably, being provided with striking nut above the convex ring of described circle, insulator body is provided with threaded hole, and striking nut is connected in threaded hole by threaded rod.
When occurring when being struck by lightning; flashover is caused to discharge between starting rod and striking nut; form short-channel; the power frequency arc continued moves to and burns between starting rod and striking nut, avoids burn for the protection of wire, owing to burning occurs between starting rod and striking nut; striking nut is often damaged; need to change, only need to change striking nut when replacing is set between striking nut and threaded rod like this, more save cost.
Preferably, described wire pressing block is provided with fin, and fin is in unwrapping wire groove both sides.
By technique scheme, fin the degree of depth that can increase unwrapping wire groove is set, it is possible to increase the contact area between unwrapping wire groove and electric wire, electric wire fixed more firm.
Preferably, described insulator body upper end is coated with insulation covering, and wire pressing block is in insulation covering.
Pass through technique scheme, it is possible to effectively prevent rainwater from entering in wire pressing block and electric wire, cause the guiding of electric wire inside to be corroded.
In sum, the utility model in contrast to the useful effect of prior art: can when installing lightning protection pillar insulator for fixing lightning protection pillar insulator provide effectively location and a holding section by preventing revolving arranging of plane, monkey wrench can be stuck in during installation and prevent revolving in plane, prevent from producing to rotate due to insulator body during fastening nut, unwrapping wire fluted shaft line direction is caused not overlap with electric wire arragement direction, prevent that revolving arranging of plane has an impact to insulator body intensity to avoid simultaneously, it is provided with circular convex ring in upper end, installation portion, to prevent that revolving plane is arranged on circular convex ring, striking nut and threaded rod split are arranged only need to change striking nut when striking nut is destroyed, save cost.
