The cable bridge comprises a horizontal section and an inclined section, and when the cable bridge is arranged on the horizontal section, one plane of the angle steel is parallel to the cable laying. However, if the cable is laid on a slope section, particularly at the intersection of the horizontal section of the bridge and a large slope angle, the right angle of the angle steel forms a tangent angle with the cable.
If the cable is laid on a slope, particularly at the intersection of the horizontal section of the bridge frame and the large slope angle, the right angle of the angle steel and the cable can form a point contact, and the outer sheath of the cable can be extruded and deformed by the right angle of the angle steel under the long-term action of the gravity of the cable and the action of the electric power formed when the cable is short-circuited. In the past, the outer sheath of the cable can be cut at the right angle of the angle steel, the outer shielding conducting layer of the cable is in direct contact with the angle steel, the outer shielding conducting layer discharges electricity to the angle steel, the cable runs for a long time, the cable main insulating layer at the discharging position of the cable and the angle steel is damaged in an insulation mode due to ignition and finally is completely broken down, and the cable conductor can cause a short-circuit accident due to grounding discharge, so that the cable cannot run safely.
The inventor also found that such accidents occur in practical applications with single core cables of the 35kV voltage class, which are caused by the unreasonable structure of the rack and the method of laying the cables. The construction specification does not have specific construction requirements in the aspect, so that the construction structure and method at the intersection of the horizontal section of the bridge and the large slope angle need to be improved, and a reasonable support structure and arrangement method are adopted to improve the operation safety of the cable and avoid the occurrence of cable grounding and short circuit accidents.
