Abstract

919,534. Cross-arms for posts. BRITISH INSULATED CALLENDER'S CONSTRUCTION CO. Ltd. Oct. 7, 1960 [Oct. 7, 1959], No. 34038/59. Addition to 745,317. Class 20 (1). A cross-arm 1 for supporting an overhead electric line is mainly of the cross-section shown and may be made by supporting eight resin bonded glass fibre rods 9 of uniform cross-section under tension within a mould, the rod ends passing through bushings at either end of the mould. A silica filled epoxy resin is used to fill the previously evacuated mould, and is cured by processing for eight hours at 160‹ C. The cross-arm is then removed from the mould, the projecting ends of the rods are cut flush with the ends of the arm and are coated with an epoxy resin sealant. Annular porcelain or resin rings 4 may be provided along the length of the arm.
