Technical Field

[0001] This utility model relates to the field of power transmission line technology, and in particular to a cable slack well. Background Technology

[0002] With the continuous development of society and economy, the demand for urban power supply is increasing, and the power load is mainly concentrated in coastal areas. Power grid investment resources are growing, and the number of power projects is increasing. In order to effectively resolve the contradiction between the high cost of transmission line cable projects and the economic investment of power grid projects, conventional cable slack wells are no longer sufficient. Previously, the commonly used cable slack well methods mainly included the following three types: The traditional U-shaped cable slack well. This type of cable slack well uses a cable trench that wraps around the outside of the cable terminal tower foundation, leading the cable down from the cable terminal tower and winding around the slack well. Excess cable is left around the inner side of the cable well; a traditional square cable well is used, which is built on one side of the cable terminal tower. Relying on the cable terminal tower, a square well of about 5m*5m*2.5m (length, width, depth) is built. The cable is led down from the cable terminal tower and enters through a reserved opening on one side of the square cable well. The cable is left around the well. A D-shaped cable well is used, which is built on one side of the cable terminal tower. The cable is led down from the cable terminal tower and enters through a D-shaped opening on one side for laying. Excess cable is left in the arc section of the D-shaped well.

[0003] However, traditional square cable manholes, rectangular cable manholes, and D-shaped cable manholes have disadvantages such as large footprint, high cost of cable construction, and long cable length. Utility Model Content

[0006] The cable excess cable well body is arranged around the power transmission line tower foundation from the side of the tower, is gathered from the front of the tower, passes through the foundation between the towers, and is connected with the cable line, thereby forming a unique W-shaped cable channel.

[0007] The support columns are symmetrically arranged at a longitudinal distance of 4m on both sides of the channel.

[0008] The cable support is provided with a cable clamp.

[0009] The number of the cable clamps is multiple, and the cable terminal column foundation is located at the hole.
