Problems solved by technology

[0004] When the cable radiation is in a strong electromagnetic environment, at the moment when the power cable is powered on and off, the power cable will jump violently due to the electrical stress, and the cable jump is easily damaged by the cable tie under the restraint of the cable tie (such as the cable The outer shielding layer is damaged) and cause the bundle to loosen; when there is a gap between the power cable and the tie, the power cable jumps again will have a greater displacement relative to the tie, and will be further damaged by the tie

Embodiment Construction

[0044] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the following further describes the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0045] In the embodiments of the present disclosure, the power cable is used to transmit and distribute high-power electrical energy in the main line of the power system, and the control cable directly transmits electrical energy from the power distribution point of the power system to the power connection lines of various electrical equipment and appliances. The rated voltage of power cables is generally 0.6 / 1kV and above, and the rated voltage of control cables is mainly 450 / 750V.

[0046] In cable laying facilities, for example, when laying cables in wire troughs, due to the limited space and long length of wire troughs, in order to lay more cables, there are the following requirements.

[0047] 1. The cables need to be neatly arranged in the w...

Abstract

The invention provides a cable duct, and belongs to the field of electrician tools. The cable duct comprises a cable duct body, a suspension frame and a fixing block, wherein the suspension frame is transversely arranged on a groove opening of the groove body; and the fixing block is located in the groove body, and a gap exists between the fixing block and the groove wall of the groove body. The fixing block comprises an upper neck and a lower neck matched with the upper neck, the upper neck is detachably connected with the lower neck, an installation channel used for containing a first cableis formed between the upper neck and the lower neck, a suspension arm is arranged on the upper neck, and the suspension arm is movably connected with the suspension frame.

Description

Technical field [0001] The present disclosure relates to the field of electrical appliances, in particular to a cable trunking. Background technique [0002] Power cables are cables used to transmit and distribute electric energy, and include power cables. Power cables are used to transmit and distribute high-power electrical energy in the main line of the power system, and the rated voltage is generally 0.6 / 1kV and above. [0003] In the power cable laying facility, the power cable can be fixed on the wall or ceiling by using a wire slot. Multiple power cables can be arranged in the wire trough. During construction, it is usually necessary to bundle the cables with plastic ties in the wire trough, or set up a bracket in the wire trough, and then tie each cable to the bracket with plastic ties. . [0004] When the cable is radiated in a strong electromagnetic environment, when the power cable is energized or cut off, the power cable will produce violent jumps due to electrical str...
