らなる支持体１、ここでは円錐台形の中空管を含む。The main structure of the insulator is manufactured by shrinking a mineral or organic fiber or filament, such as glass fiber, which is hardened by a curable synthetic resin containing, for example, an epoxy resin, to form a layered insulating layer of a composite material. It comprises a support 1 made of material, here a hollow tube of frusto-conical shape.

The insulating material is used to expand the leakage path of the insulator and enhance the airtightness of the casing.

Before fixing 3 and 3 to the support 1, each metal fitting and each contact surface at the end of the support are cut so that the diameter of each ring is slightly smaller than the diameter of the contact surface into which the ring is inserted. And are processed. In the case of a support having an outer diameter of 100 to 300 mm, a tightening margin of several mm, which is about 0.4 mm, is suitable. Of course, in order to obtain a mechanical clamping force that remains within the elastic limits of the materials of which the supports and fittings are made, the working tolerances of the rings and abutment surfaces must be defined.

グの直径の方が若干大きくなる。Next, the metal fitting is placed in a heater and heated at about 160 ° C. for several hours. Due to the action of this thermal stress, the ring of each metal fitting expands, and the diameter of the ring becomes slightly larger than the diameter of the contact surface on which the ring is attached.

られる。During the heating operation of the metal fittings, the support 1 made of a layered material is used to position and insert each metal fitting at each end of the support along the longitudinal axis of the support, such as a steady rest. It is mounted on a lathe equipped with suitable centering means.
【００１６】金具を加熱器から取り出す数分前に、当接

る。During assembly, a rotary groove (annular band) is machined on the surface of each ring in order to form a packing made of an adhesive and ensure its airtightness. In order to ensure the airtightness, it is appropriate that the thickness of the groove is about several tenths of a millimeter.

も必要ではない。It should be noted that the work of inserting the respective metal fittings into the end of the support must be carried out extremely quickly, in less than 5 minutes. This is because the ring of each metal piece tends to shrink rapidly at room temperature of about 20 ° C. However, since the support 1 made of the layered molding is already installed at a position where the metal fitting can be easily inserted, the same holding time is sufficient even if the correct work is performed, and a complicated tool is not necessary.
