TECHNICAL FIELD

[0002] Cable is a kind of power or signal transmission device, which is usually composed of several or several groups of wires and has the characteristics of internal power supply and external insulation. Cable can be used to transmit electric (magnetic) energy and information, and realize electromagnetic energy conversion. There are various types of cables, including power cables, control cables, compensation cables, shielded cables, high-temperature cables, etc. They are composed of single or multiple wires and insulation layer, used to connect circuits and electrical appliances. Cable bridge is divided into slot type, tray type and ladder type, net type structure, which is composed of support, supporting arm and installation accessories, etc. The bridge in the building can be independently erected, or attached to various buildings and pipe gallery supports, which should have the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance, etc. All parts need to be galvanized.

[0003] In the process of laying some cables, the functional characteristics of cable bridges are applied to various industry application scenarios, and the stepped cable bridge has the characteristics of good ventilation effect and light weight and is widely used. However, due to the characteristics of cable bridge, the cables are disordered when laying cables, the space in the bridge is crowded (more than 40% to 50% of the cross-sectional area) due to too many cables, the heat dissipation is poor and insulation aging is easily caused, and the cables in the vertical bridge are not fixed or not fixed firmly, which may cause loose connection or outer skin wear due to gravity sagging. The existing stepped cable bridge lacks the function of limiting and fixing the cables and lacks the function of adjusting the width according to the actual needs, thereby causing poor use effect.
