Description

Technical Field

[0001] This utility model relates to the field of cable tower technology, and in particular to a multi-platform cable terminal pole. Background Technology

[0002] Cable terminal towers are required at the connection points between 220kV and above cable lines and overhead lines. Currently, conventional cable terminal towers use a single-terminal platform method to connect to the overhead line. However, after years of operation, the following problems have been found: First, due to the high clearance requirements of the 220kV voltage level, the distance between each piece of equipment must be greater than 2m to 3.5m. Since there are a total of 6 groups of three-phase equipment, the distance between each pair must be greater than the safe operating distance, resulting in a large cable platform area. Second, in order to reduce electromagnetic circulation, the surge arrester is generally placed close to the tower body, and the cable terminal is placed away from the tower body. Since the cable terminal and the cable must be on the same center line, the area occupied by the cable terminal tower is generally the outer contour area of ​​the cable platform, thus the area occupied is large.
