Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway overhead line construction, in particular to a conductor clamping hardware for a straight pole tower of a railway overhead through-line which is convenient for fastening. Background Art
[0002] At present, pin-type or column-type insulators are generally used in the straight pole towers of railway overhead through-line, and the conductors and insulators are mostly tied and fixed by the "cross-tying method". The tying method mainly has the following problems: First, the conductor tying is a high-altitude operation, which is inconvenient to operate and takes a long time to tie; second, improper construction or vibration of the conductor during operation due to strong winds and ice cover will cause the tying wire to loosen and cause a flying accident, and the flying of the tying wire may cause a short circuit between phases or a grounding short circuit fault; third, under the influence of load current and external temperature during operation, the conductor and the tying wire have different degrees of thermal expansion and contraction, and the contact area between the tying wire and the conductor is small, causing the insulation of the insulated conductor to be damaged or the outer strands of the bare conductor to be scattered. Therefore, in order to improve the reliability of the railway overhead through-line and ensure the safe operation of the railway, it is necessary to design a new type of conductor clamping hardware for the straight pole tower of the railway overhead through-line.
