A cable pay-off support bracket

Abstract

A cable pay-off support bracket relates to a sheathed cable pay-off frame. The lower surface of the upper frame body (1) is provided with an upper groove plate (2) with a downward notch, and two upper axles (6) are respectively provided at both ends of the upper groove plate (2). It is fixedly connected to the front and rear sides of the upper groove plate, and the upper groove plate (5) is respectively provided in the middle of the two upper wheel axles; Both ends of the two lower axles (12) are fixedly connected to the front and rear sides of the lower groove plate, respectively, and lower sheaves (13) are respectively arranged in the middle of the two lower axles; the upper frame body and the lower frame body are connected with the lower frame body through the two upper The device is integrated, and the middle of the two sides of the frame body of the integrated structure is respectively provided with a V-shaped depression for being stuck on a step, a wall corner or a right angle of the wellhead; the present invention obtains the cable through the V-shaped depression on both sides of the frame body. Right-angle wear at corners or wellheads.

Description

technical field [0001] The invention relates to a sheathed cable pay-off rack, in particular 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 bushings and aluminum bushings. Due to the high insulation performance required, a metal protective layer with a wall thickness of not less than 1.2mm needs to be set on the outside of the buried cable. An isolation layer "insulation lining" is set between the cables. When the cable is erected and inserted into the well, the surface is easily worn by the steps restricted by the site, the corners of the wall and...

[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
