Cable pay-off supporting bracket

Abstract

The invention discloses a cable pay-off support bracket, and relates to a leather cable pay-off rack. An upper groove plate (2) with a downward groove opening is arranged on the lower surface of an upper frame body (1), two ends of two upper wheel shafts (6) are fixedly connected to the positions, close to the front side face and the rear side face, of the upper groove plate correspondingly, upper groove wheels (5) are arranged in the middles of the two upper wheel shafts correspondingly, a lower groove plate (16) with an upward groove opening is arranged on the upper portion face of a lower frame body (17), the two ends of two lower wheel shafts (12) are fixedly connected to the positions, close to the front side face and the rear side face, of the lower groove plate correspondingly, lower groove wheels (13) are arranged in the middles of the two lower wheel shafts correspondingly, the upper frame body and the lower frame body are integrated through two upper and lower frame body connectors, and the middle parts of the two side surfaces of a frame body with the integrated structure are correspondingly provided with V-shaped recess used for being clamped at a step, a wall corner or a wellhead right angle. According to the cable pay-off supporting bracket, through the V-shaped recesses on the two sides of the frame body, the cable is prevented from being abraded by the step, the wall corner or the wellhead right angle during paying off.

Description

technical field [0001] The invention relates to a sheathed cable pay-off frame, in particular the invention relates to a cable pay-off support bracket. Background technique [0002] It is known that in view of the needs of urban development and aesthetics, cables are buried underground through cable trenches in many areas. Compared with overhead lines, buried cables have the advantages of small footprint, reliable power transmission performance, and strong anti-interference ability, which are very suitable for overall planning. ;Buried cables are roughly divided into two categories: copper casing and aluminum casing. Due to the high insulation performance required, a metal protective layer with a wall thickness of not less than 1.2mm needs to be installed on the outside of the buried cable. An isolation layer "insulation inner lining" is set between the cables. When the cable is erected into the well, because it is hard, the appearance is easily worn by the steps, corners an...

[0002] It is known that in view of the needs of urban development and aesthetics, cables are buried underground through cable trenches in many areas. Compared with overhead lines, buried cables have the advantages of small footprint, reliable power transmission performance, and strong anti-interference ability, which are very suitable for overall planning. ;Buried cables are roughly divided into two categories: copper casing and aluminum casing. Due to the high insulation performance required, a metal protective layer with a wall thickness of not less than 1.2mm needs to be installed on the outside of the buried cable. An isolation layer "insulation inner lining" is set between the cables. When the cable is erected into the well, because it is hard, the appearance is easily worn by the steps, corners and right angles of the wellhead when the site is restricted. In the long-term use The service life of the cable will be greatly shortened if the worn part is attacked by moisture, soaked in rain, etc. When a short-circuit current occurs, it will cause a great impact or serious accident on the substation equipment
