Abstract
The utility model relates to a DC two-sided anti-interference control cable for track traffic, which comprises a plurality of pair conductive bodies with twisted pair wires, an inner lining layer and an oversheath coated outside the pair conductive bodies with twisted pair wires, wherein an isolating layer and a shielding layer are coated outside each pair conductive body with twisted pair wires, and a shielding layer with a copper belt and a shielding layer with a high-magnetism guiding steel belt are orderly arranged between the inner lining layer and the oversheath. The utility model has favorable insulating and shielding properties, and interference of an extraneous signal can be excluded by using the utility model in a two-sided anti-interference control system for track traffic. Meanwhile, external disturbance of a direct-current pulse is decreased, misoperation can not be generated by controlled equipment and running security and reliability are enhanced.
Description
Technical field
The utility model relates to a kind of electric equipment control cable, especially track traffic DC control cable.
Background technology
The control cable that is used for the direct current interlock tripper in the existing track traffic control cable that adopt common system strand more, the characteristics that this cable incompatibility direct current signal is carried, the frequent break-make that connection is jumped device can produce impulse disturbances, may make controlled device produce misoperation, thereby cause major accident.
Summary of the invention
Be not suitable for the problem used in order to solve existing general control cable in this particular surroundings of track traffic, the utility model provides a kind of bilateral jumping control cable that can satisfy the control of DC traction electric power, can satisfy the requirement of using in track traffic.
The track traffic that the utility model provides comprises uplink and downlink with the bilateral jumping of direct current control cable many twisted pair wires are to conductor (1) and be coated on its outer inner covering (5) and oversheath (9), every twisted pair wire is surrounded by separator (3) and screen (4) to conductor (1) is outer, sets gradually copper strips screen (6) and high magnetic conduction steel band screen (8) between inner covering (5) and oversheath (9).
For the twisted pair wire that makes the utility model uplink, downlink to reducing impulse disturbances between conductor, the twisted pair wire of uplink or downlink is provided with unequal to the pair twist pitch of conductor.
The beneficial effects of the utility model are: have good insulation performance and shielding properties, satisfied the electromagnetic compatibility requirement of track traffic with cable, the transmission that is used for control signal in the bilateral jumping of track traffic control system can be got rid of the extraneous signal interference, signal externally disturbs in preventing simultaneously, controlled device can not produce misoperation, improves the fail safe and the reliability of operation.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1. twisted pair wire is to conductor, 2. insulating layer of conductor, 3. separator, 4. screen, 5. inner covering, 6. copper strips screen, 7. drainage thread, 8. high magnetic conduction steel band screen, 9. oversheath.
Embodiment
Twisted pair wire adopts copper cash to make through continuous casting and rolling, annealing, crosslinked polyetylene insulated layer of stranded back outsourcing to conductor (1); Separator (3) adopts wrapped the forming of two-layer polyester band; Screen (4) adopts soft copper band vertical bag outside separator (3) to form; Copper strips screen (6) and high magnetic conduction steel band screen (8) compound wrapped forming outside inner covering (5); The contact of two screens is also established drainage thread (7) betwixt; Inner covering (5), oversheath (9) adopt the halogen-free and low-smoke flame-retardant polyolefin material to extrude and form.
Claims (2)
1, a kind of track traffic bilateral jumping of direct current control cable, many twisted pair wires that comprise uplink and downlink are to conductor and be coated on its outer inner covering and oversheath, it is characterized in that every twisted pair wire is surrounded by separator and screen outward to conductor, between inner covering and oversheath, set gradually copper strips screen and high magnetic conduction steel band screen.
2, by the described track traffic of claim 1 with the bilateral jumping of direct current control cable, the twisted pair wire that it is characterized in that uplink and downlink is provided with unequal to the pair twist pitch of conductor.
