Embodiment Construction

[0011] like figure 1 As shown, the present invention includes a FRP mandrel 1 and a sheath 2 and an umbrella shed 5 located outside the FRP mandrel 1 . The diameter of the end 3 where the above-mentioned FRP mandrel 1 is connected to the hardware is larger than the diameter of the FRP mandrel 1 .

[0012] In order to meet different needs, the above-mentioned end 3 can be one of spherical, elliptical, semicircular and semielliptical.

[0013] A connection device between a fiberglass tensile insulator and a fitting, which includes a fiberglass insulator and its connecting fitting 4, the terminal 3 connecting the fiberglass insulator to the fitting is one of a sphere, an ellipse, a hemisphere, and a semiellipse, and the connecting fitting 4 The joint with the fiberglass mandrel 1 is a round hole.

[0014] The diameter of the above-mentioned circular hole is larger than the diameter of the FRP mandrel 1, and smaller than the diameter of a sphere, an ellipse, a semi-sphere or a s...

Abstract

The invention discloses a glass fiber reinforced plastic stretching insulator that comprises a glass fiber reinforced plastic core rod, a sheath and a parachute skirt, wherein the sheath and the parachute skirt are arranged outside the glass fiber reinforced plastic core rod; besides, the diameter of an end socket where the glass fiber reinforced plastic core rod is connected with a hardware fitting is larger than the diameter of the glass fiber reinforced plastic core rod. According to the above-mentioned technical scheme in the invention, because the core rod is glass fiber that has been extruded much, the core rod can bear great forces; therefore, the structure enables forces to be directly exerted on the glass fiber reinforced plastic core rod and the core rod can bear great forces.

Description

technical field [0001] The invention relates to a fiberglass stretch insulator and a connecting device, which connects the fiberglass stretch insulator and fittings together. Background technique [0002] Existing FRP insulators are fixed fittings at the mandrel end, which are connected with other components, so that the fixing method of the fittings and the mandrel is the occlusal fixing of the FRP and the fittings. This way is only the force on the periphery of the mandrel, and cannot maximize the use of the mandrel to transmit force. Contents of the invention [0003] The object of the present invention is to provide a fiberglass stretch insulator which utilizes mandrel to transmit force to the maximum, and provide a connecting device between the fiberglass stretch insulator and a fitting. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] The invention comprises a fiberglass core rod, a sheath and an umbrell...
