Description

A support frame for cable maintenance

technical field

The utility model relates to a support frame, in particular to a support frame for cable maintenance, which belongs to the maintenance equipment of electric facilities.

Background technique

Cable is a general term for items such as optical cables and cables. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, power transmission, etc. It is a common and indispensable thing in daily life. Since the cables are live, installation requires special care. Power cables are extruded (winded) around the conductor with an insulating layer, such as overhead insulated cables, or twisted with several cores (corresponding to the phase wire, neutral wire and ground wire of the power system), such as overhead insulated cables with more than two cores, or additional Sheath layer, such as plastic/rubber sheathed wire and cable. Main technology has drawing, stranded, insulation extruded (wrapped), stranding, armouring, sheath to extrude etc., and the different process combination of various products has certain difference. Since power cables are generally erected in the air for power transmission, under the long-term effects of the natural environment, etc., local cracks or pollution of the cables will occur, which will affect the power transmission. In this case, maintenance is required. In some places, the roads are inconvenient, large-scale lifting equipment cannot enter, and maintenance personnel can only enter the site with their own tools. The cable is erected in the air and is set between two cables. Go to the pole or tower and then move along the cable to the position that needs maintenance. Some individual cables are suspended in the air and have a small diameter. The maintenance personnel cannot step on the cable to operate, which makes it very troublesome for the maintenance personnel to reach the maintenance personnel, and there is a big problem for the maintenance personnel. security risks.
