Abstract

The invention discloses a pre-twisted fitting for an aerial optical cable, relating to the field of electric power fittings. The optical cable comprises mounting brackets, movable assemblies, a supporting piece, a left fixing assembly, a right fixing assembly and an optical cable assembly. The supporting piece is fixedly arranged in the middles of the mounting brackets, and the two movable assemblies are movably installed on the mounting bracket on the two sides of the supporting piece. The left fixing assembly and the right fixing assembly are connected with the movable assemblies on the twosides respectively, the optical cable assembly penetrates through the left fixing assembly, the supporting piece and the right fixing assembly to be fixedly connected, and the supporting piece is fixedly connected with the left fixing assembly and the right fixing assembly through rigid springs respectively. Through the spiral line structure of the inner and outer double-layer twisted wires, the grip to the optical cable is improved, and the reliability of optical cable connection is ensured; and meanwhile, the wind resistance and the pulling resistance of the connected cable are improved while the rigid strength of connection is ensured, the optical cable is prevented from being broken due to too strong stress, and the service life of the optical cable is prolonged.

Description

technical field [0001] The invention relates to the field of electric fittings, in particular to a pre-twisted fitting for overhead optical cables. Background technique [0002] Power fittings are metal accessories that connect and combine various devices in the power system to transmit mechanical loads, electrical loads and some kind of protection. Iron or aluminum metal accessories widely used in transmission lines are collectively referred to as fittings. There are many types of fittings with different uses, for example, various clamps for installing wires, various hanging rings for forming insulator strings, various crimping tubes and repair tubes for connecting wires, and various types of spacers for splitting wires In addition, there are various types of wire fittings used for poles and towers, as well as the size of the protective wires, which must cooperate with each other. [0003] In overhead lines, it is often necessary to connect overhead and install multiple g...
