Abstract

The invention relates to a bundled conductor supporting armor clamp. The armor clamp comprises a connecting base plate fixedly connected to a supporting insulator, a direction corresponding to an extension direction of a bundled conductor is defined as an installation direction, the connecting base plate is provided with at least two spacer installing plates which are distributed separately along the installation direction successively, each spacer installing plate is provided with a spacer in the side surface vertical to the installation direction, each spacer includes lead clamps arranged along the circumferential direction of the spacer, and the number of the lead clamps of each spacer is the same with that of the other spacers. Separate distribution of the bundled conductor is realized, and the bundled conductor is supported so that the bundled conductor is prevented from downward swinging due to the deadweight. The connecting base plate is provided with at least two spacer installing plates which are distributed separately, multi-point support for the bundled conductor is formed, stress concentration in the bundled conductor is alleviated effectively, bearing of the bundled conductor is optimized, and the power transmission stability and reliability of the bundled conductor are improved.

Description

technical field [0001] The invention relates to a split wire supporting hardware. Background technique [0002] With the rapid development of domestic DC converter station technology, the UHV converter stations are connected by aluminum stranded wires, and the aluminum stranded wires are connected according to a certain split spacing to reduce the surface potential gradient and prevent the gap between wires in the case of short circuit. There is no electromagnetic force that causes mutual attraction and collision, and the influence of vibration caused by strong winds is suppressed. In order to ensure the spacing of the aluminum strands, wire spacers are usually set between the aluminum strands. [0003] Traditional wire spacers, such as the "six-split wire spacer for transmission lines" disclosed in the Chinese patent literature with the authorized announcement number CN201018242Y, include a hollow support frame, and six are evenly distributed around the circumference of the...
