Embodiment Construction

[0042] The present invention will be further described below with reference to the accompanying drawings.

[0043] see Figure 1 to Figure 4 As shown, the present invention provides an embodiment: a method for erecting an all-dielectric self-supporting optical cable based on a double angle steel main material iron tower includes the following steps:

[0044] Step S1, selecting the hanging point position of the all-dielectric self-supporting optical cable 10 according to the distribution of the electromagnetic field intensity and the distribution position of the cable drain wire 14;

[0045] Step S2, by selecting the special ADSS splint 12 of the cross-type double-joint angle steel main material iron tower, it is used for the hanging of the tower body double-joint angle steel main material 9 below the lower rung, thereby solving ADSS in the cross-type double-joint angle steel main material iron tower the hanging problem;

[0046] Step S3, hanging the all-dielectric self-suppo...

Abstract

The invention provides a method for erecting a full-dielectric self-supporting optical cable based on a double angle steel main material iron tower, comprising the following steps: step S1, selecting the hanging point position of the full-dielectric self-supporting optical cable; step S2, selecting a special ADSS splint ; Step S3, the all-dielectric self-supporting optical cable is solved by hanging on the special ADSS splint to solve the problem of tower overload and electromagnetic field strength distribution; Step S4, making the round head flat steel length of the special ADSS splint longer than The length of the insulator of the iron tower diversion line solves the situation where the optical cable and the diversion line collide with the wind; step S5, calculate the maximum critical sag value of the optical cable in the tension section; step S6, check the tower load; step S7, if the tower load cannot be satisfied Strength, it is necessary to increase the position of the hanging point of the optical cable under the premise of step 01, adjust and increase the sag; step S8, if the load of the iron tower is met, adjust the sag within the range; the present invention can be solved by a special ADSS splint The problem of hanging the main material tower of cross-shaped double angle steel.

Description

technical field [0001] The invention relates to the technical field of arc sag erection of all-dielectric self-supporting optical cable (ADSS) power transmission lines, in particular to the erection of all-dielectric self-supporting type of terminal towers of cross-shaped double-jointed angle steel main materials for power transmission lines of various voltage levels from 110kV to 500kV The method of erecting an all-dielectric self-supporting optical cable based on the double-spliced ​​angle steel main material iron tower is designed in the optical cable. Background technique [0002] With the rapid development of my country's power communication network construction, all-dielectric self-supporting optical cable (ADSS) can solve some large spans, excessive wire sag, etc. The advantages of 110kV and above voltage level lines cannot be powered off when OPGW is erected and the existing line tower ground frame optical cable cores are not enough. It is widely used in power communi...
