The invention relates to electrical engineering, namely, supporting insulators and Can be used as supports for electrical devices with different potentials. And 1

Structures of supporting insulators are known, the insulating part of Kordpiiix is assembled from btd & insulating elements And with the connecting fittings in the form of rods and sleeve packs. Interconnection of such structural elements; insulators is carried out with the help of the arMyruk Shay link, for example, sand and cement; solution

In view of the fact that insulating seshemengs have reinforced surfaces of different sizes and sizes, they absorb impregnation and various types and sizes of production equipment, and insulators, respectively, have high envelope, material consumption, and mass.

These deficiencies are eliminated in the supports of Yykh izol; ytorah, the insulating part is of the same type of insulating) (elements {2.

The known supporting high-grade insulator is a column consisting of three Multicon-type supporting insulators, each of which is assembled from separate porcelain of the same type with insulating elements with conical connecting surfaces interconnected and connecting fittings with cement mortar. The insulating elements of these insulators have smooth conic joints which, in the assembled insulator, are installed with the possibility of overlapping two or three insulating elements, which contributes to increasing the rigidity and strength of the costructure only if it is subjected to compressive forces. . This also contributes to the annular platform, located at the base of the cone with the possibility of contact, by means of a layer of reinforcing binder, c. the inner edge of the adjacent insulating element. However, due to the low mechanical strength of the cement or sand-cement solution, its weak coupling with the surface to be reinforced, the insulating elements under the action of bending moments and tensile forces are removed from each other, as a result of which insulators have insufficient reliability and durability in operation. In addition, the absence of the Moloi ylRo1MoTru1: y8nSH: 5Lenov to seize the reinforcing linkage and convert the tensile forces to compressively decreases the mechanical characteristics as a reinforcing linkage, as a whole. . .... The purpose of the present invention is to eliminate the indicated disadvantages, i.e., to increase the reliability and mechanical strength of the insulator. This is achieved in that in a known reference insulator; containing an insulating part interposed between the connecting reinforcement consisting of interconnected reinforcing binder of the same insulating elements; On the outer surface of the conical section of each insulating element, a protrusion is made in the form of a truncated cone with a taper, the inverse conicity of the conical section, and on its internal surface in the area of the protrusion of another insulating element, a groove is made, the shape of which repeats protrusion.

The provision of an insulating part of a supporting insulator with conical protrusion and groove sections on the conic sections improves the insulator's reliability, reduces its height and increases the mechurea strength under the action of not only compressive forces and bending moments, but also tensile forces, which makes it possible to use Such an insulator in the core structures of insulators designed for tensioning and supporting a wire of an overhead transmission line. In addition, by making the protrusion with a taper, the reverse taper of the conical section, there is a real possibility of reducing the height of the insulating element, increasing the mechanical strength of their power (reinforced) units, to assemble the supporting and core insulators from a larger number of insulating elements and thereby to minimize the number intermediate connecting metal fittings in the insulator column and, thus, to obtain the optimum value of the ratio of the single leak to the height of the insulator and, therefore, use them in areas with a high level of atmospheric pollution.
