本発明を２個連続して吊り下けた状態を示す。Then, the recess 2b of the head 2a of the pin 2 is fitted into the protrusion (center guide) 7 provided with the recess 7a at the center of the interior of the main body 1. So the center is completely capable. Next, main body 1
Casting resin 13 is injected into the bowl-shaped main body 1 to the position shown by the dotted line inside the main body 1, and is left to solidify for several hours, thereby fixing the pin 2 of the main body 1 integrally. At this time, the casting resin 13 permeates into the groove 5 on the inner peripheral surface of the main body 1 and the grooves 2a, 7, and 2b of the head portions 2b of the pin 2, thereby acting as tension between the main body 1 and the pin 2.
In addition, the casting resin has adhesive properties over a wide area and generates a large tensile strength. Afterwards, insert the bolt 3 between the clevises 10 and 1' and tighten the nuts 4 and 4 on both sides.
The pin 2 can be either the hook type pin shown in Figure 6 or the standard type pin shown in Figure 7, depending on the purpose of use. Figures 2 and 3 are shown in the book. This figure shows a state in which two inventions are hung in succession.

がいしを提供することができる。The broken line in FIG. 2 is the surface leakage distance, and indicates that in the present invention, if two or more insulators are used in succession, the leakage distance increases synergistically, and the insulation resistance increases. In the present invention, since there is no metal member between consecutive insulators, it is safe to assume that the capacitance is zero, and in FIGS. 2 and 3, the second series of pins is a hook-shaped pin. This shows that the electric wire 12 is supported by this hook-shaped pin. As mentioned above, the present invention is an insulator in which the main body, pins, and bolts are molded entirely from plastic, so compared to conventional porcelain insulators, it has revolutionary electrical insulation resistance and enormous tensile and bending strength. It has come to meet all the conditions necessary for an insulator, such as heat resistance, cold resistance, weather resistance, non-adhesiveness, water repellency, and oil repellency, as well as absolute capacitance and infinite insulation resistance. and the weight is 6.5 lbs. compared to conventional porcelain insulators.
It is less than half the weight of a porcelain insulator, and is approximately 1C lighter than a porcelain insulator.
It is possible to perform high-speed production of 0 and provide highly durable insulators at low prices.
