Suspension hardware fitting for optical phase conductor

Abstract

The invention relates to a suspension hardware fitting for an optical phase conductor. The suspension hardware fitting comprises internal twisted wires, external twisted wires, a rubber fixture block, a cast aluminum shell, a socket clevis, an insulator string, a ball eye and a U-shaped suspension loop, wherein the external twisted wires clad the optical phase conductor; the external twisted wires clad the internal twisted wires; the rubber fixture block is arranged between the internal and external twisted wires; the cast-aluminum shell is arranged outside the rubber fixture block and the external twisted wires; the lateral surface of the cast-aluminum shell is sequentially connected with the socket clevis, the insulator string consisting of a plurality of series-wound insulators, the ball eye and the U-shaped suspension loop; the other end of the U-shaped suspension loop is connected with a tower and a fixed suspension hardware fitting; and the U-shaped suspension loop may be of an A type, a B type or a C type. The suspension hardware fitting provided by the invention is used for suspending an optical phase conductor cable on the tower; and due to the adoption of a pre-twisted suspension clamp, the suspension hardware fitting greatly improves the stress bearing capability of the optical cable on the basis of meeting a supporting function, and can prolong the service life of the optical cable.

Description

technical field [0001] The invention relates to a matching fitting for an optical fiber composite overhead phase line (OPPC), in particular to a hanging fitting for an optical fiber composite overhead phase line. Background technique [0002] Suspension fittings, that is, suspension clamps, can fix wires on insulator strings or hang lightning conductors on straight poles and towers. They are also used to support transposed wires on transposition towers, and to fix jumpers on tension-resistant and corner towers. The hanging fittings mainly play a supporting role, and each straight tower is equipped with a set. [0003] The general technical requirements for pendant fittings are as follows: [0004] The hanging angle of the hanging fittings is not less than 25°; [0005] The radius of curvature of the hanging fittings is not less than 8 times the diameter of the wire to be installed; [0006] The percentage values ​​of the holding force of the hanging fittings on different ...

AI Technical Summary

Problems solved by technology

[0009] Stress concentration, the gravity of the wire in the entire span section is concentrated on the hanging fittings, which will easily cause the optical fiber unit in the OPPC wire to deform, thereby affecting the communication channel

[0010] The bending radius is small. Although the existing hanging fittings are protected by protective wires, the entire clip body is too short, resulting in too small bending radius, which easily leads to damage to the quality of the optical fiber in the wire.
