Description

Energy-saving suspension clamp for double conductors

Technical Field

The utility model relates to a suspension clamp technical field specifically is an energy-saving suspension clamp is used to two wires.

Background

Suspension clamps generally have old-fashioned ship type clamps: the wire clamp can be used as a lightning conductor. The cable clamp can bear the installation load of a lead in a vertical span, and the cable clamp is not allowed to slide or separate from an insulator string when a line normally runs or is broken, so that the bearing pressure of a tower using the cable clamp is high. The preformed suspension clamp has the functions and the purposes that: the single-side suspension angle is 15& ordm-18& ordm, and the combination of the inner and outer layers of spiral pre-twisted wires can well protect the optical cable, has no concentrated stress, avoids generating bending stress, and plays roles of protecting and assisting in damping the optical cable. The whole set of suspension clamp comprises: the inner-layer pre-twisted wire, the outer-layer pre-twisted wire, the suspension head and the matched connecting hardware fitting. The grip strength of the cable clamp is 10% -20% higher than the rated tensile strength of the optical cable, and the installation is convenient. The suspension clamp comprises a hanging rack, a U-shaped screw and a ship body. There is a limit to the suspension clamp with respect to maximum deflection angle. When the ship body rotates to a certain angle, the U-shaped screw is blocked by the hanging frame. The maximum deflection angle is also a safe operating condition. The maximum deflection angle is related to the overhang angle of the lead or the ground wire on two sides of a pole tower suspension point and the diameter of the lead and the ground wire (the outer diameter of the lead should include the thickness of an aluminum-wrapped tape or the diameter of a wire protection strip), and the larger the diameter is, the more the U-shaped screw moves upwards, the smaller the maximum deflection angle is. If the deflection angle is larger than the maximum deflection angle, measures are taken, such as changing a double wire clamp, adjusting the tower height, or specially designing a novel wire clamp and the like;

however, most of suspension clamps are rigid at present, and particularly in the process of electric power installation, the working condition of up-down suspension often appears, and the conventional suspension clamp cannot realize the integral suspension of double conductors, so that the operation is inconvenient.
