Embodiment Construction
[0012] The present invention will be further explained below in conjunction with specific embodiments, but the present invention is not limited thereto.
[0013] Such as figure 1 , figure 2 As shown, the present invention provides a novel strain clamp, comprising: an aluminum tube 1, a steel anchor 2 and a pre-twisted wire 3, wherein one end of the aluminum tube 1 is tightly connected to the steel anchor 2, and the other end is connected to the steel anchor 2 Aerial wire connection, the outer circumference of the aluminum tube 1 is provided with a groove that matches the pre-twisted wire 3, one end of the pre-twisted wire 3 is wound around the outer circumference of the overhead wire and wound in the groove on the outer circumference of the aluminum tube 1 along the overhead wire And compressed, the other end of the pre-twisted wire 3 is used to be wound on the drainage wire.
[0014] The new strain clamp replaces the bolt fastening structure in the existing strain clamp wi...

The invention discloses a novel strain clamp, comprising: an aluminum tube, a steel anchor and a pre-twisted wire, wherein, one end of the aluminum tube is fastened to the steel anchor, and the other end is connected to an overhead wire, and the aluminum tube The outer circumference of the aluminum tube is provided with a groove that matches the pre-twisted wire. One end of the pre-twisted wire is wound on the outer circumference of the overhead wire and wound in the groove on the outer circumference of the aluminum tube along the overhead wire and pressed tightly. The other end of the pre-twisted wire For wrapping around drain wires. The structure of the new tension clamp is reasonable, and the pre-twisted structure is used to replace the bolt fastening structure of the existing tension clamp. Under the condition of ensuring the mechanical and electrical properties, the problem caused by the loosening of the bolts is avoided from the root. .
Description
technical field [0001] The invention relates to a fixing device in a power transmission line, and in particular provides a novel tension clamp. Background technique [0002] The tension clamp is used to fix the wire or lightning protection wire on the tension insulator string of the non-linear tower, and it acts as an anchor. It is also used to fix the guy wire of the guy tower. It is an important fitting in the transmission line. The overhead transmission line aims to build an "environmentally friendly" project, comprehensively optimize the design of the project, and strictly ensure that the electric field, magnetic field, audible noise and radio interference levels meet the standard requirements. [0003] At present, the commonly used hydraulic tension clamps are mainly divided into double-plate tension clamps and single-plate tension clamps according to the structure of the drainage plate. For areas with severe breeze vibration and frequent galloping, it is often The phe...
