Abstract

PURPOSE:To enable to fasten tentatively the title thermal recovery article under a positioning state without holding a material to be coated even if the same is in a round shape and a perpendicular state by placing the material to be coated into a narrow width part which is in an odd-shaped cross-sectional shape when the same is fitted over the material to be coated, by forming synthetic resin into a cylindrical shape which is in an odd-shaped cross-sectional shape by making use of synthetic resin to which thermal recovery treatment has been applied. CONSTITUTION:In case coating is applied to a perpendicular part of a power cable 2, a thermal recovery article 1 is fitted over a position of the cable 2 whereon the article 1 is going to be coated. As the thermal recovery article 1 is formed into an odd-shaped cross-sectional shape, a narrow width part is put to the power cable 2 from both sides of the same and positioning is performed under a tentatively fastened state without falling down even if the power cable 2 is in a round cross section and, moreover, in a perpendicular state. As for the thermal recovery article 1, similar tentative fastening is obtained even if it is ellipse or square. In addition to the above, in case the coating is applied to a plurality of the articles at a time, it is easily possible to fasten the articles tentatively under a positioning state without generating a separation or fall even if the articles each connected in order with each other into a partly fitting state are fitted over the power cable.
