For fixing metal sheaths on glass fiber reinforced plastic rods, which rods are used, for example, in composite insulators: the sheath is in a number of sections in a longitudinal array; there is an abutment inside the sheath at each sheath section, there is a shoulder piece on the outside of the rod inside each sheath section; the abutment in a sheath section is at one longitudinal side of the respective shoulder piece in that sheath section; elastic and compliant buffer means, such as springs, or the like, are placed between the abutment and its shoulder piece; the compliance of the buffer means increases toward one end of the arrangement to compensate for the different rates of expansion of the sheath and the rod; other embodiments all have appropriate buffer means in each sheath section, which buffer means increase in compliance moving toward the end of the sheath through which the rod exits. |
