Embodiment Construction

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as there is no conflict with each other.

[0032] like figure 1 and figure 2As shown, this embodiment provides a cable terminal rod, which is suitable for the connection of high voltage, especially 220kV and above overhead lines and cable lines, including a rod body 1 and a cross arm assembly installed on the upper end of the rod body 1, the cross a...

Abstract

The invention provides a cable termination pole comprising a pole body and a cross-arm assembly arranged on the pole body top; the cross arm assembly comprises at least three cross arm structures; each the cross arm structure is respectively used for connecting an overhead conductor and a jumper wire connected with the cable terminal; the three layers of cross arm structures comprise the lower cross arm structure, the middle cross arm structure and the upper cross arm structure arranged in order from bottom to top; each cross arm structure layer is respectively connected with one phase overhead conductor, so the three cross arm layers are connected with three phase staggered overhead conductors; the cross arms used for connecting jumper wires in every two cross arm structures can mutually form an angle, so one pole body can enable all cross arms used for connecting jumper wires to be positioned in different vertical planes, thus staggering corresponding jumper wires in the space, and preventing transmission line short circuit or faults; in addition, the pole body takes small land area, is easy to construct, and low in cost.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a cable terminal rod. Background technique [0002] With the rapid development of the current social economy, due to the disadvantages of large space occupation and poor environmental appearance of overhead transmission lines, cable lines are gradually replacing overhead lines in urban areas and become the main transmission form of urban high-voltage transmission lines . At present, 220kV and above transmission lines located in the suburbs mostly adopt the form of overhead transmission, and those located in the urban areas of large and medium-sized cities mainly adopt the form of cable transmission, and the connection structure of 220kV overhead lines and cable lines is the weak point of the current high-voltage transmission network, which directly affects the city. Whether the transmission line can run normally and stably, the connection structure between the e...
