    Abstract: A method is disclosed for producing an optical fiber composite insulator, including the steps of: preliminarily heating the insulator body in its entirety at not less than 70.degree. C., then filling said organic insulating material into the through hole while said at least one optical fiber is being stretched straight, and then curing the organic insulating material by heating in a temperature range of not less than 75.degree. C. but not more than 90.degree. C. while at least one optical fiber is kept stretched straight.

    Abstract: An excellent optical fiber built-in type composite insulator is provided having a reliable and durable sealing portion in a central axis penetration hole of the insulator for sealing the optical fiber in a very quick, simple and economical way with reduced members, devices and production steps. The composite insulator includes a ceramic insulator having a penetration hole in its central axis portion, at least one optical fiber inserted in the penetration hole, and sealing portions made of inorganic glass arranged at both ends of the penetration hole for sealing the optical fiber therein, and comprises recessed portions of the ceramic insulator arranged around the ends of the penetration hole, and heat generating elements arranged in the recessed portions for heating and melting the inorganic glass to form the sealing portions at the both ends of the penetration hole. The present invention provides also a method of producing the composite insulator.

    Abstract: The invention provides an electrical insulator comprising a cylindrical core (2) of an insulating refractory material, such as porcelain, onto a portion of the curved surface of which a sleeve (8) of insulating polymeric material is fitted. Metal end-caps (4), for electrically connecting the insulator, are fitted to the ends of the porcelain core such that there is an exposed portion (10) of the curved surface of the core between the sleeve and each end-cap. Thus, any damaging electrical activity which takes place at the metal end-caps is directed primarily onto the surface of the porcelain core (2), and not onto the surface of the electrically vulnerable polymeric sleeve (8), which serves to protect mechanically the relatively brittle porcelain core. Optionally, the polymeric sleeve (8) may have a convoluted or a shedded outer surface (12) to increase the leakage path length of the insulator, or to prevent the formation of a continuous moisture path, or both.

    Abstract: In an overhead electric and optical transmission system in which at least one of the overhead electric conductors incorporates an optical guide, the overhead electric conductor is mechanically secured to a tower or other rigid support structure by a mechanical connection in which an end of the overhead electric conductor is mechanically secured to and is electrically insulated from the tower or other rigid support structure by an elongate tension insulator having at least one throughbore, the optical guide of the conductor passes from the conductor through the throughbore of the tension insulator to an optical guide joint remote from the insulator, and the electric conductor is electrically connected to another electric conductor. The tension insulator may be a shedded body of porcelain or glass having a central throughbore or it may be a rod or tube of resin bonded glass fibre surrounded by a shedded sleeve of plastics material having at least one throughbore extending throughout the length of the wall of the sleeve.
