Description
Technical field
The present invention relates to transmission line of electricity technical fields, and in particular to a kind of cable terminal pole.
Background technology
With the rapid development of current social economy, since overhead transmission line has, space is larger, environmental beauty
The disadvantage of difference, within the scope of city proper, cable run gradually substitutes overhead transmission line, becomes city ultra-high-tension power transmission line
Main transmission of electricity form.Currently, 220kV and the above transmission line of electricity, which are located at suburb, mostly uses overhead power transmission form, it is located at large and medium-sized city
City urban district mainly uses cable power transmission form, and the connecting structure of 220kV overhead transmission lines and cable run is current high voltage power transmission
The weak spot of network, can directly affect city transmission line of electricity normally, steadily run, existing 220kV overhead transmission lines and electricity
Cable road connecting structure is commonly cable and angle steel tower connection type, and this connection type takes up a large area, and construction requirement is high, straight
Connect influence project progress.
The patent document of Publication No. CN203951149U discloses a kind of double loops 220kV cable terminal pole and corresponding
Transmission system, cable terminal pole include the long and short two root body of rod, coupling beam, cross-arm, expenditure insulator and cable termination holder；Coupling beam
The long and short two root body of rod is connected to form double-rod structure, cross-arm includes upper layer, middle level and lower layer's cross-arm, and cross-arm is pacified at the middle and upper levels
On compared with long rod, middle level cross-arm is mounted in the coupling beam of the top, and lower layer's cross-arm is mounted on compared on quarter butt body；Aerial condutor with
Strain insulator-string connection on cross-arm, and jumper connection is supreme draws string, above draws to go here and there and is connected to cable termination by lead, and cable termination is placed on
On cable termination holder, every one end of cross-arm, which is all connected on a strain insulator-string and one, draws string, since the cable terminal pole is applicable in
