1,076,952. Insulators. COMPAGNIE GENERALE D'ELECTRICITE. Aug. 14, 1964 [Aug. 20, 1963; Jan. 16, 1964], No. 33390/64. Heading H2C. An electrical strain insulator is made by winding glass or other insulating fibres over two shouldered members, which are spaced apart by a rigid insulating connector member, so that a tubular body with approximately spherical end-caps is formed thereupon. As shown in Fig. 2, metal members 5, 6 are joined by a fibreglass tube 1, which can be filled with compatible material through holes 9, 10, glass fibres being wound over the assembly to form coating 8. The fibres follow long pitched spiral paths along the tubular portion and geodesic curves over the ends. They may be impregnated with thermosetting resin. The insulator may have an external coating of arc resistant material such as polytetrafluoride. Discharge guards may be provided along the body of the insulator and it may have a ceramic or other arc-resistant outer casing. |
