Abstract
Deep-well waterproof-type earthquake-situation monitoring signal transmission cables belong to the field of cable technology and comprise cable cores which form the cables through insulating wires with insulating layers in insulating bodies and external protecting covers, and are characterized in that the cable cores are provided with internal cores and external cores, the internal cores comprise two opposite stranded-wire groups which surround and wrap polyester PE with internal insulating layers after constituting the cables, the external cores comprise many opposite stranded wire groups surrounding around the internal cores, the polyester PE with external insulating layers are wound and wrapped in the cable cores, tin-plating copper-wire shielding layers are knitted in the external insulating layers, the external protecting covers are arranged at the shielding layers. The utility model has the advantages that the structure is reasonable and simple, producing and manufacturing are easy, and cost is low. The cables have the advantages of excellent insulating performance, enduring high or low temperature, water resistence, moisture resistence, corrosion prevention, quick signal transmission speed, stability, reliability, satisfaction of demand for earthquake monitoring and forecaste with modern instrument and meter systems. The utility model is used to monitor the earthquake-situation monitoring signal transmission before earthquake in deep wells.
Description
Technical field
The utility model relates to a kind of structure of signal-transmitting cable, and particularly deep-well earthquake situations monitor signal transmission cable belongs to the cable technology field.
Background technology
Because earthquake brings in various degree threat and loss in the generation of different degree from different places, for people's lives and properties.For strengthening monitoring and forecast work to earthquake situations before the shake of earthquake, carry out the precautionary measures of resisting earthquake disaster conscientiously, assure the safety for life and property of the people, various places have been strengthened the earthquake situations monitoring of earthquake and the input of forecast work.Existing cable can not satisfy seismic monitoring and forecast the requirement of using the modern equipment instrument system, is badly in need of a kind of earthquake situations monitor signal transmission cable that is used for deep-well monitoring waterproof.
The utility model content
The purpose of this utility model is exactly for satisfying the needs in market, a kind of good insulation preformance is provided, waterproof, high-low temperature resistant, the deep-well water proof type earthquake situations monitor signal transmission cable that signal transmission performance is good.
The purpose of this utility model is to realize like this, deep-well water proof type earthquake situations monitor signal transmission cable, comprise cable core and oversheath by the insulated wire stranding of tape insulation layer on the conductor, it is characterized in that described cable core is provided with inner core and outer core, the interior separator of wrapped polyester PE band constituted after inner core was formed cable by two groups of twisted pair wires, outer core constitutes around being enclosed in inner core by many groups twisted pair wire group, the outer separator of wrapped polyester PE band on the cable core, weave the tinned copper wire screen outside on the separator, oversheath is arranged on the screen.Described conductor is a multiply silver-gilt copper wire twisted bundles.Insulating barrier is a polytetrafluoroethylene.Be provided with the nylon rope filler in the cable core.Oversheath is a waterproofing type silicon rubber, is extruded on the screen.
The utility model is rational in infrastructure simple, and the manufacturing is easy, cost is low.Cable has good insulation preformance, and high-low temperature resistant is waterproof and dampproof, and is corrosion-resistant, and signaling rate is fast, and is reliable and stable, satisfies seismic monitoring and the requirement of forecast with the modern equipment instrument system, can be used for the preceding earthquake situations signal-transmitting cable of deep-well monitoring shake.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
1 conductor among the figure, 2 insulating barriers, 3 fillers, 4 interior separators, 5 outer separators, 6 screens, 7 oversheaths.
Embodiment
Outer surface at multiply silver-gilt copper wire twisted bundles conductor 1 extrudes teflon insulation layer 2 formation insulated wire, becomes the twisted pair wire group by two insulated wire pair twists.Form behind the cable by two groups of twisted pair wires that separator 4 constitutes inner core in the wrapped polyester PE band.The outer core of 11 groups of twisted pair wire groups formations is set around inner core and is twisted into cable core, in inner core, outer core, nylon rope filler 3 is set with inner core.The outer separator 5 of wrapped polyester PE band on the cable core, braiding tinned copper wire screen 6 on the separator extrudes waterproofing type silicon rubber oversheath 7 on screen 6 outside.
Claims (5)
1, a kind of deep-well water proof type earthquake situations monitor signal transmission cable, comprise cable core and oversheath by the insulated wire stranding of tape insulation layer on the conductor, it is characterized in that described cable core is provided with inner core and outer core, the interior separator of wrapped polyester PE band constituted after inner core was formed cable by two groups of twisted pair wires, outer core constitutes around being enclosed in inner core by many groups twisted pair wire group, the outer separator of wrapped polyester PE band weaves the tinned copper wire screen outside on the cable core on the separator, and oversheath is arranged on the screen.
