Problems solved by technology

The cause of malfunction is: the distributed capacitance increases. When the control circuit is DC grounded or AC is connected in series, the power supply forms a circuit with the relay through the distributed capacitance of the cable. When the control contact is not closed, the relay of the control equipment will malfunction. verb: move

Embodiment Construction

[0013] Further illustrate the present invention in conjunction with accompanying drawing and embodiment, as shown in Figure 1, the present invention comprises conduction core wire 1 and is arranged on the insulation inner sheath 5 of conduction core wire 1 outside successively, flame-retardant tape 6, polyester tape 7, A shielding layer 8 and an outer sheath 9 , wherein the conductive core wire 1 includes a conductor wire 2 and an insulating layer 3 covering the conductor 2 .

[0014] The present invention strengthens the insulation between the cable core and the shielding layer through the insulating layer 3 on the periphery of the conductor 2 and the insulating inner sheath 5, and reduces the distributed capacitance value of the cable, so that the distributed capacitance is reduced to 80r-F~120r·F, In the process of signal transmission, it can effectively avoid the occurrence of equipment malfunction and increase the reliability of the circuit. The present invention does not...

Abstract

The invention relates to a control cable, is used for long-distance signal transmission, and belongs to the technical field of industrial control cables. According to the control cable, insulation situation between a cable core and a shielding layer is reinforced both in an insulation sleeve in the periphery of a conductor wire and an insulation inner sheath, thereby reducing a distributed capacitance value of the cable, the distributed capacitance is reduced to 80rlF to 120rlF, generation of equipment misoperation is effectively prevented in a signal transmission process, and reliability of a loop is increased.

Description

technical field [0001] The invention relates to a control cable, which is used for long-distance signal transmission and belongs to the technical field of industrial control cables. Background technique [0002] In some large-scale industrial projects, there are long distance control loops. Due to the increase in the number of units, the distance between the switch station and the units gradually increases, and some will reach nearly two kilometers. The distributed capacitance of the cable will not cause misoperation when the distance is short, but when the distance is too long, the distributed capacitance cannot be ignored, and it is easy to cause equipment misoperation when the DC is grounded and the AC is connected in series. [0003] The malfunction caused by the long cable is mainly through the distributed capacitance between the core and the shield (ground). The cause of malfunction is: the distributed capacitance increases. When the control circuit is DC grounded or...
