Dimensions of ball and socket couplings of string insulator units

Applies to string insulator units of the cap and pin and long rod types and their associated metal fittings for overhead lines. Includes six standard sizes designated by the nominal pin diameters which form the basis of the standard. Defines each standard size by the dimensions of the pin ball, of the socket and the hook-on 'Go' gauge. States dimensions of twin-balled pins for coupling of two sockets. Tabulates clearance and locking conditions. Appendices give information on extreme positions of the pin ball in the socket as well as on gauges for checking dimensions.

Dimensions des assemblages à rotule et logement de rotule des éléments de chaînes d'isolateurs

S'applique aux éléments de chaînes d'isolateurs du type capo et tige et du type fût long ainsi qu'à leurs accessoires métalliques pour lignes aériennes. Contient six normes d'assemblage définies par les diamètres de tige nominaux qui constituent la base de la norme. Définit chaque norme d'assemblage par les dimensions de la tige à rotule, du logement de rotule et du calibre d'accrochage "Passe". Indique les dimensions des haltères pour la liaison de deux logements de rotule. Groupe dans les tableaux le jeu et les conditions de verrouillage. Les annexes donnent des informations sur les positions limites de la tige à rotule, l'intérieur du logement de rotule ainsi que les calibres de vérification pour les dimensions.
