Description
Technical field
The present invention relates to a kind of cable, especially a kind of communication, monitoring cable.
Background technology
It is monitoring circuit running situation, master control room understands circuit operation conditions at any time, along height when ultra-high-tension power transmission line is laid
Pressure transmission line by parallel lay-up monitor and guide cable.But when ultra-high-tension power transmission line is struck by lightning, switching overvoltage occurs or
When failure punctures, larger induced voltage is will appear from neighbouring monitoring and guide cable, typically can reach 15kV or so.Simultaneously
Above-mentioned monitoring and guide cable each pair core are responsible for transmitting different signals, control different electric devices to act, to avoid letter
Interfered between number, special design structure need to be used, ensure the accurate of signal transmission.Therefore it is parallel along ultra-high-tension power transmission line
Monitoring/guide cable of laying, it is impossible to common control signal cable is used, except conductor and insulation size external diameter, line are to process
Pitch should be controlled accurately, ensure that signal is undistorted, not outside interaction crosstalk, it is also necessary to cover electrostatic screen and steel wire using copper strips+lead
Magnetic shielding is combined, and effectively shields electromagnetic field caused by high-tension line, ensures that monitoring and signal of communication are interference-free, it is ensured that
Power distribution equipment normal work.
General control cable is only capable of bearing 3kV or so induced voltage, and single metallic shielding structure can not be effective
Shield ultra-high-tension power transmission line electromagnetic field effects, it is impossible to be used in ultra-high-tension power transmission line.And the project cable can bear 15KV or so senses
Voltage is answered, available for ultra-high-tension power transmission line.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of communication, monitoring cable, ensure that cable core unit is normal
Operation, signal stabilization transmission.
In order to solve the above technical problems, the technical solution adopted in the present invention is：One kind communication, monitoring cable, including it is more
Group insulated wire pair, the insulated wire provided with two insulated wire cores, the insulated wire cores to including conductor and PE insulating barriers；It is described exhausted
Ointment is filled between edge line pair, is coated with PET strip, MDPE inner sheaths, copper strips, lead set and first successively outside insulated wire pair
Non-woven fabrics belting layer, steel wire armor layer is externally provided with the first non-woven fabrics belting layer.
Preferably, the steel wire armor layer is located at the inside of bitumen layer.
Preferably, the bitumen layer is externally provided with the second non-woven fabrics belting layer and oversheath.
Preferably, the insulated wire is to there is 20 groups.
Preferably, the twisting pitch of adjacent insulated wire pair is different.
Preferably, the bitumen layer uses anti-water complex pitch.
Preferably, the cable and high voltage power cable parallel lay-up.
One kind provided by the invention communicates, monitoring cable, has the advantages that：
1st, the wrapped PET strip of cable core external series gap, cable core factice for filling, it is the longitudinal water-blocking characteristic for realizing cable.
2nd, insulation thickness and external diameter accurately control, and each adjacent lines ensure cable during 1kHz to using different pair twist pitches
Mutual capacitance is not more than 54nF/km, and capacity unmbalance can reach within 20pF/500m between line pair, and decay is not more than 0.5 dB/
km。
3rd, cable core peripheral hardware copper strips is wrapped and extrusion lead sheath electrostatic screen layer adds wire armoring magnetic shielding layer to be：When super
When ultra-high-tension power transmission line occurs short-circuit, electromagnetic field caused by high-tension cable can be effectively shielded.In addition, steel wire armor layer can be born
Larger mechanical external force, it can effectively protect lead set and cable core internal structure injury-free.
4th, only once mounting is needed to lay, you can to ensure the stability of line signal transmission to greatest extent, save tradition
Control and time and the expense of signal cable later maintenance and replacing, effectively reduce every cost.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
