Forging integrated type oiling strain clamp for aluminum alloy stranded wire

Abstract

The invention provides a forging integrated type oiling strain clamp for an aluminum alloy stranded wire. A strain clamp is arranged on an overhead transmission line terminal and is used for anchoring a wire and keeping the electric and mechanical properties of the wire; the strain clamp is characterized in that the strain clamp comprises a pull ring, a connecting pipe and a drainage wire clamp; the connecting pipe and the pull ring are integrally formed along an axial direction; a fixing component and a pulling pin are respectively arranged on the inner wall and the outer wall at one end of the connecting pipe; an oiling hole is arranged in the side wall of the connecting pipe at a joint of the connecting pipe and the pull ring. Compared with the prior art, the forging integrated type oiling strain clamp for the aluminum alloy stranded wire provided by the invention has the advantages that the strain clamp is prevented from being damaged by inner frozen accumulated water, the strength of the strain clamp is increased, the holding capability of the strain clamp for the wire is increased, and a mature crimping technique is adopted so that the crimping quality is excellently ensured.

Description

technical field [0001] The invention relates to a strain clamp, in particular to a forged integral oil-filled strain clamp for aluminum alloy stranded conductors. 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, which plays an anchoring role, and is also used to fix the guy wire of the guy tower. It is an important fitting in the transmission line. [0003] The UHV project aims to build an "environmentally friendly" project, comprehensively optimizes the design of the project, and strictly ensures that the electric field, magnetic field, audible noise and radio interference levels meet the standard requirements. For this reason, a new type of all-aluminum alloy twisted wire structure wire is designed to ensure the current carrying capacity of the transmission conductor. While ensuring the power transmission capacity of the wire, the weight of the wire is reduced, and ...

Problems solved by technology

[0004] Due to the wide coverage of the UHV project, the geographical environment involved, and the complex weather, some areas have long-term low temperature and more rainfall. In this environment, if the tension clamp has a certain upward angle, the rain It will flow into the tension clamp along the gap inside the wire, causing the corrosion of the tension clamp. If it encounters low temperature weather, the accumulated water inside the tension clamp will freeze. There will be phenomena such as pipe expansion, which is prone to accidents
