Description
(1), technical field: the utility model relates to a kind of cable, and particularly one row hangs and uses flat cable.
(2), background technology: along with development and the progress of society, the security performance that row hangs more and more causes the attention of people.Existing row hangs in the process of walking, does not have voice message, does not have warning device, does not also have monitor video, so, very in situation of easily causing danger in the course of the work, time serious, also personnel death's accident can be caused.Trace it to its cause, wherein have a very important problem exactly: the flat cable that existing row hangs middle use only can transmit power electric, does not have signal transfer functions, is unfavorable for installing and using very much of alarm monitor.
(3), utility model content:
The technical problems to be solved in the utility model is: provide a kind of row to hang with flat cable, this cable has voice, video, alarm signal and electric power transfer function, and its transfer function is strong, transmission quality good.
The technical solution of the utility model:
A kind of row hangs with flat cable, containing oversheath, outer shielding layer and cable core, outer shielding layer is located at the outside of cable core, oversheath is located at the outside of outer shielding layer, cable core contains insulation fill stratum and N root cable, N root cable is located in insulation fill stratum side by side, containing two composite signal lines and N-2 root power transmission line in N root cable, containing O root voice signal line in every root composite signal line, P root alarm signal line and a video signal cable, video signal cable is positioned at the central authorities of composite signal line, O root voice signal line and P root alarm signal line are positioned at around video signal cable, voice signal line is two heart yearns, alarm signal line is single-core line, video signal cable is the single-core line of sheath and screen in addition, N be more than or equal to 5 natural number, P be more than or equal to 2 natural number, O be more than or equal to 1 natural number.
Two composite signal lines lay respectively at the both sides of N-2 root power transmission line.
The span of the span of N to be the span of 5 ~ 7, P be 2 ~ 5, O is 1 ~ 4.
Outer shielding layer contains metal wire knitted screen and insulation screen, and metal wire knitted screen is located at the outside of insulation screen.
Flexible wire ropes is embedded with, the pulling force of flexible wire ropes on load-bearing cable in the both sides of oversheath.
The material of power transmission line is high-test metal soft copper, and insulation fill stratum is extruded by cross-linking polyethylene materials and forms, and insulation screen is extruded by semiconductive material and forms, and oversheath is extruded by high-strength polyurethane and forms.
The beneficial effects of the utility model:
1. power transmission line both sides of the present utility model are provided with two composite signal lines, containing voice signal line, alarm signal line and video signal cable in composite signal line, like this, the utility model can not only carry out electric power transfer, can also realize the transmission of voice, video, alarm signal, transfer function is strong, and does not interfere with each other between each signal, effectively ensure that transmission quality, and construction install convenience.
(4), accompanying drawing illustrates:
Fig. 1 is the structural representation that row hangs with flat cable cross section;
Fig. 2 is the structure for amplifying schematic diagram of composite signal line cross section.
(5), embodiment:
