Description
Technical field
The present invention relates to electric wire field, refer in particular to a kind of security type optical fiber composite medium-pressure cable.
Background technology
The world today is the stepped into information epoch, information has become the strategic resource of economic development and unique production factors, to combine the present information transmission system and complete information service system set up with multimedia terminals such as telecommunications network, computer, videos, become the important symbol of a country economic development level.Optical fiber composite cable is the important kind of one in information transmission, main be used as radio transmission or receiving equipment feeder and various communication, electronic equipment machine intraconnections or be interconnected line.
Optoelectronic composite cable is applicable to make transmission line in broadband access network system, is a kind of novel access way, and its light harvesting fibre, transmission of electricity copper cash, in one, can solve the problem of broadband access, equipment electricity consumption, Signal transmissions.Its conventional structure be copper conductor together with fiber unit stranding, or using the filling part of fiber unit as other cables.
The shortcoming that this technology exists in important goal or military use, is easily intercepted fiber-optic signal by people cause the leakage of a state or party secret; In addition, the difference very of the crushing resistance existing for existing technology.
Summary of the invention
It is little that the technical problem to be solved in the present invention is to provide a kind of external diameter, lightweight, take up room little, cost is low, waterproof good, security type optical fiber composite medium-pressure cable.
For solving the problems of the technologies described above, the invention discloses a kind of security type optical fiber composite medium-pressure cable, comprising cable core, being provided with lapping layer, inner sheath and oversheath successively outward at cable core; Described cable core forms by three optical fiber compound wire core are stranded; Described optical fiber compound wire core by bosom fiber unit, be arranged on the hollow conductor outside fiber unit and be extruded in conductor shield outside hollow conductor successively, insulating barrier, insulation screen, the first compression tube form; The second compression tube is provided with between inner sheath and oversheath.
Further improvement, described fiber unit is made up of two optical fiber placed side by side and the copper pipe be enclosed within outside optical fiber.
Further improvement, the first described compression tube is the plastic flexible pipe of left-hand thread type structure.
Further improvement, the second described compression tube adopts that internal layer is crossed through insulation processing, that skin is provided with PVC plastic film galvanized steel strip.
Compared with prior art, its beneficial effect is in the present invention:
1, the present invention in use, cable conductor normal power-up uses, the fiber unit transmission light signal of telecommunication in the middle of conductor, because the conductor outside fiber unit is charged, except non-fully destroys cable, others cannot steal the fiber-optic signal in the middle of charged conductor, does not then also exist divulged a secret as destroyed cable completely; Fiber unit is placed on cable conductor center, and the core of conduction protects optical fiber unit, can effectively prevent from being stolen signal by people from fiber unit.
2, flexible pipe has splendid waterproof, insulating properties, pull resistance, and hose surface adopts PVC material, and to the addition of fire-proof flame-retarded agent structure in PVC plastic be left-hand thread type, add tensile strength, be not easy to fracture or be out of shape, good bending property, inside smoothly constructs, when connecting electric wire and easily.
3, the second compression tube adopts that internal layer is crossed through insulation processing, that skin is provided with PVC plastic film galvanized steel strip, and have shield effectiveness function, mechanical strength is high, compressive property good, and moistureproof and good airproof performance, can improve its bending property.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
