The top end of the column leg module 1 and the bottom end of the column breath height adjusting module 2 are respectively fixed with a flange 41, the two flanges 41 are connected through fastening bolts, the top end of the column breath height adjusting module 2 and the bottom end of the terminal platform module 3 are respectively fixed with one flange 41, and the two flanges 41 are connected through fastening bolts.
A plurality of reinforcing ribs 42 are respectively fixed on the other side surfaces of the two correspondingly connected flanges 41 at intervals, and the reinforcing ribs 42 on each flange 41 are uniformly distributed in a circular shape at intervals. A plurality of reinforcing ribs 42 are respectively arranged between the top end of the column leg module 1 and the flange 41 connected with the column leg module, and between the bottom end of the column breath height adjusting module 2 and the flange 41 connected with the column breath height adjusting module. A plurality of reinforcing ribs 42 are respectively arranged between the top end of the column breath height adjusting module 2 and the flange 41 connected with the column breath height adjusting module, and between the bottom end of the terminal platform module 3 and the flange 41 connected with the column breath height adjusting module.
Cylinder shank module 1 includes terminal support post main part 11, draws down cable cross arm 12, and the bottom of terminal support post main part 11 is fixed with ground, and the top is breathed high regulation module 2 with the cylinder and is connected, draws down cable cross arm 12 on terminal support post main part 11 upper portion horizontal installation on its global, and the height L of terminal support post main part 11 is 4500 ~ 5000mm, draws down the interval between cable cross arm 12 and terminal support post main part 11 top and is 500 ~ 800 mm.
The column body height calling adjusting module 2 comprises a terminal support column main body II 21 and a down-leading cable cross arm II 22, the bottom end of the terminal support column main body II 21 is fixed with a terminal support column main body I11, the top end is connected with the terminal platform module 3, the down-leading cable cross arm II 22 is arranged on the terminal support column main body II 21 at least at intervals along the height direction of the down-leading cable cross arm II, the two down-leading cable cross arms are respectively and horizontally arranged on the peripheral surface of the down-leading cable cross arm II, and the height A of the terminal support column main body II 21 is 3000-3500 mm.
The flange 41 may be a circular ring structure, and the diameter of its inner ring is equal to the outer diameters of the first terminal support column body 11, the second terminal support column body 21, and the third terminal support column body 31.
The required calling height is determined according to factors such as operating units, design specification requirements, line importance and the like, and different calling heights of the cable terminal platform are realized by increasing or decreasing the number of the column calling height adjusting modules. After the foundation is finished, the 3 types of different modules are firstly assembled, the number of the column breath height adjusting modules is determined according to the actual needs on site, and the other two modules are respectively assembled by 1.
The installation of the column leg module, the column breath height adjusting module and the terminal platform module is completed from bottom to top; different modules are connected by adopting a flange assembly.

The cable terminal platform of different heights of exhaling can satisfy the passageway requirement that the cable draws down at ordinary times, can directly demolish a grade of cylinder when the cable terminal head trouble is salvageed and breathe out high regulating module (for example demolish first grade regulating module (A) by L + A + T and become forms such as L + T, can continue to use), it breathes out high regulating module height A installation to be about to fall a cylinder of present terminal platform cable terminal, has realized that the surplus cable of cable sets up corresponding function. The removed column breath height adjusting module can be repeatedly used for other projects.
Traditional cable terminal towers need to build surplus cable trenches and matched large terminal field fences (enclosing walls), the occupied area is large, for example, the occupied area of a terminal field needs to be about 80 square meters for a common 110kV overhead line; after reconstruction, only the occupied area of the tower and cable support column foundation is about 10 square meters, and the occupied area is reduced by about 87.5 percent; and traditional cable termination field needs a large amount of surplus cable to lay, and the actual surplus cable utilization ratio is lower, and is extravagant great. The design adopts a relatively standardized cable terminal scheme, so that the land occupation is greatly reduced, and the design is more environment-friendly; the cable material and construction cost are reduced; the convenience of first-aid repair is improved, and the operation and maintenance cost is reduced.
3. For important customers (or other extreme conditions needing to be considered), production operation unit opinions can be combined, an adjustable terminal support is utilized, meanwhile, a terminal field (a residual cable trench and a terminal field fence) is newly built, the combined use of residual cables is achieved, and the problem of 1-2 times of fault first-aid repair of cable terminal outgoing lines can be solved by utilizing the cable terminal support at ordinary times. If the outgoing line is in an extreme condition, the flexible adjusting function of the residual cables in the residual cable trench and the adjustable cable terminal bracket adjusting module can be utilized, the possibility of repairing and utilizing the residual cables m times by n (m is generally determined by the quantity of the residual cables in a terminal field and the quantity of the residual cables used in single repairing, and n is the quantity of the column body height calling adjusting modules of the adjustable cable terminal) is realized, and the guarantee under various extreme conditions is greatly improved.
The standardized cable terminal supports with different specifications can be manufactured according to different voltage grades, and the column breath height adjusting module is arranged according to the tower design concept, so that the adjustment of the cable terminal support under the lead-out can be realized conveniently; different breathing heights are connected by flanges, and the device can be assembled in a split mode and can be reused.
Traditional terminal field generally is limited to surplus cable ditch size, and place in service behavior, surplus cable generally can only use once, and the surplus cable is reserved longer (generally ten several meters at least), only about 3m during actual use, has great waste, and salvagees once after, and this section cable has basically not had the trouble of surplus cable and salvages safeguard function.
And the mode of surplus cable + adjustable cable terminal support adjusting module in the surplus cable ditch in the face of extreme condition makes the surplus cable use amount of single trouble of surplus cable reduce to 3m, not only makes surplus cable adjust the number of times and has realized the multiplier level and increase, has still improved salvage surplus cable utilization efficiency greatly.
