Cable terminal steel pipe pole

Abstract

The invention discloses a cable terminal steel pipe pole which comprises a main pole provided with cross bars, a lightning arrester and a cable terminal joint and further comprises a cable terminal support layer used for concentrated arrangement of cable terminal joint, a lightning arrester support layer used for concentrated arrangement of the lightning arrester and a silicon stick support layer. The main pole is provided with the cable terminal support layer, the lightning arrester support layer, the silicon stick support layer and a plurality of cross bars in sequence from bottom to top. The cable terminal joint is arranged on the cable terminal support layer. The lightning arrester is arranged on the lightning arrester support layer. The cable terminal support layer, the lightning arrester support layer and the silicon stick support layer are additionally arranged on the main pole so that concentrated installation and debugging of the cable terminal joint and the lightning arrestor can be achieved, working intensity of field installation, debugging and overhauling by a worker is reduced greatly, the length of a cable needed is reduced greatly, cost is reduced effectively and copper materials are saved.

Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a steel pipe pole for a cable terminal. Background technique [0002] The steel pipe poles at the cable terminals are usually used to lead the cables to the cross-arm brackets of each layer. The length of the poles on each cable varies greatly, and a lot of precious non-ferrous metals (copper) will be consumed in vain. Since my country's copper reserves are not large, and copper is a valuable national defense material, most of it can only be imported, so it is very meaningful to save copper. [0003] figure 1 and figure 2 Shows the basic structure of a traditional cable terminal steel pipe pole. When building traditional steel pipe poles for cable terminals, workers need to install and debug cable terminals and lightning arresters layer by layer, which is inconvenient for construction and labor-intensive. At the same time, in the later work of cable lead-in...

Problems solved by technology

When building traditional steel pipe poles with cable terminals, the staff need to install and debug the cable terminals and lightning arresters layer by layer, which is inconvenient for construction and labor-intensive

At the same time, in the later work of cable lead-in corresponding to the cable terminal head and lightning arrester, it also needs to be installed and debugged layer by layer, which is inconvenient for construction and labor-intensive. is longer, such as figure 1 For the traditional cable terminal steel pipe pole with three layers of cross arms shown, the cable length required for the uppermost layer is often tens of meters longer than that required for the bottom layer

In addition, there are still such defects in the use of traditional steel pipe poles for cable terminals: it is difficult to fix the cables, it is difficult to handle the electrical gaps, and the iron parts around the cables are prone to heat, and special technical treatment is required for the iron parts, etc.
