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 purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0045] In the embodiment of the present disclosure, the power cable is used in the main line of the power system to transmit and distribute high-power electric energy, and the control cable directly transmits the power from the power distribution point of the power system to the power supply 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 construction, for example, when laying cables in wire slots, due to the limited space and long length of wire slots, in order to lay more cables, the following requirements are required.

[0047] 1. The cables need to be placed neat...

The cable trough includes: a trough body, a suspension frame and a fixing block, the suspension frame is arranged transversely on the notch of the trough body, and the fixing block is located in the trough body and exists between the trough wall of the trough body gap, the fixed block includes an upper card slot and a lower card slot matched with the upper card slot, the upper card slot and the lower card slot are detachably connected, and the upper card slot and the lower card slot An installation channel for accommodating the first cable is formed between them, and a suspension arm is provided on the upper slot, 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 duct. Background technique [0002] Power cables are cables used to transmit and distribute electrical energy, including power cables. Power cables are used to transmit and distribute high-power electric 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 construction, the power cable can be fixed on the wall or ceiling by using the wire groove. Multiple power cables can be arranged in the trunking. During construction, it is usually necessary to bundle the cables with plastic cable ties in the trunking, or set a bracket in the trunking, and then use plastic straps to bind each cable on the bracket separately. . [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 viol...
