Abstract
The present invention discloses a high-rise building engineering used mobile monitoring signal cable with an ethylene propylene rubber insulated chlorinated polyethylene sheath. The cable is characterized by comprising three power core main conductors which are arranged in a triangle, and a sheath layer, wherein the power core main conductor is coated by a power core and a data signal core insulation layer; the power core and the data signal core insulation layer are coated by a shielding layer; each adjacent two power core main conductors is provided with a neutral conductor therebetween; three communication cable conductors are arranged at the center of the triangle of the three power core main conductors; and the neutral conductor and the communication cable conductors are both coated by a power core and a data signal core insulation layer. According to the invention, the communication cables are designed to be on the inside of the power cables, and the protection layer of the power cables can protect the thin communication cables as well, so that the safety of the operation of the communication cables is ensured, the image is clearer than that of wireless monitoring, and the interference of external power supply signals is prevented.
Description
Technical field
The present invention relates to cable; The field specifically belongs to a kind of high building project ethylene-propylene rubber insulated chlorinated polyethylene sheath mobile monitoring signal cable.
Background technology
Along with China's skyscraper is built more and more, architectural engineering is in operation with elevator, the phenomenon of people, same year of goods or overload is comparatively general, so that architectural engineering elevator security incident constantly occurs, all bring greater loss for country and victim family, use wireless signal monitoring, can't satisfy on distance and the height transmission to data-signal, designed for communications cables is inner at power cable, can solve the smooth problem of the clear and distance of wireless surveillance poor TV signal transmission, as long as the elevator operation just can implementing monitoring.
Summary of the invention
The purpose of this invention is to provide a kind of high building project ethylene-propylene rubber insulated chlorinated polyethylene sheath mobile monitoring signal cable; designed for communications cables is in the inside of power cable; the protective layer of power cable has been protected tiny telecommunication cable simultaneously; guaranteed the safe operation of telecommunication cable, more clear than the image of wireless monitor.Not being subject to extraneous power supply signal disturbs.
Technical scheme of the present invention is as follows:
A kind of high building project ethylene-propylene rubber insulated chlorinated polyethylene sheath mobile monitoring signal cable, include three and be the power core leading body that triangle is arranged, external sheath layer, power core leading body is coated with power core and data signal line core insulation layer, power core and data signal line core insulation layer are coated with screen, be respectively equipped with neutral conductor between the adjacent power core leading body, be positioned at three centers that are the power core leading body that triangle arranges and be provided with three telecommunication cable conductors, neutral conductor, the telecommunication cable conductor is coated with power core and data signal line core insulation layer.
Be filled with packed layer in the described external sheath layer.
Beneficial effect of the present invention is as follows:
1. electrical source of power is designed to mobile flexible cable with cable.
2. designed for communications cables is shield type network data line, prevents that power supply is to the interference of data-signal.
3. cable conductor copper bar: oxygen-free copper bar, the resistivity of copper is less than 0.017241 Ω .mm2/m (20 ℃).
4. after the annealed copper wire after the wire drawing carries out annealing in process, adopt compound bundle strand, the twisting pitch ratio is less than 14 times.Make the conductor of cable more soft, be easy to bending.
5. the composite material of ethylene-propylene rubber insulated is adopted in insulation, guarantees that namely the superior isolation performance guaranteed again softness and mechanical performance.
6. the conductor of the conductor of telecommunication cable and power cable is consistent, and medium density polyethylene is adopted in insulation, has guaranteed the clarity of signal of transfer of data.
7. at the plastic-aluminum combined screen of outer wrapped one deck of telecommunication cable, solved the interference of power supply to data-signal.
8. the insulated wire cores of telecommunication cable and power cable is carried out when the semi-finished product stranded so that telecommunication cable and power cable are safe and reliable when bending is moved.
Description of drawings
Fig. 1 is structural representation of the present invention.
