Fig. 40. Suspended or Disk Type of Insulator Many line insulators are of the yetiicMat type and are made upin various shapes and sizes. The larger size porcelain insulators aremade up in two or more pieces which are fastened together by meansof a paste formed of litharge and glycerin. The advantages ofthis form of construction are greater uniformity of structure, andthat each part may be tested separately. For the higher potentials—voltages from 60,000 to 110,000—asuspended or disk type of insulator is now in use, its constructionbeing shown in Fig. 40. The advantages of this insulator are: (1) 74
