The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, the CCTV special combination cable that a kind of low-smoke non-halogen flame-retardant, protection against rodents, tension, shielding and Electro Magnetic Compatibility are good, cost is low, wiring is neat, non-maintaining is provided, can be widely used in field of network communication.
the technical scheme that the utility model adopts is: a kind of protection against rodents type of the utility model CCTV special combination cable, comprise protection against rodents type low-smoke and halogen-free flame retardant polyolefin jacket layer and be arranged on the interior braided steel wire screen of low-smoke and halogen-free flame retardant polyolefin jacket, be provided with the low smoke halogen-free flame-retardant polyolefin sheath in described braided steel wire screen, the low smoke halogen-free flame-retardant polyolefin sheath is provided with the polyester film lapping layer, be set in the polyester film lapping layer with many shadow data line, power line, the cable core that twists together around coaxial cable, wherein every pair of data lines is provided with individual screen layer and restrictive coating, described data wire is for twisting respectively to and be provided with aluminum foil composite tape and zinc-plated channelizing line and independent restrictive coating, coaxial cable is provided with individual screen layer and restrictive coating, and model is RG59 characteristic impedance 75 Ω.The utility model is not only power supply power transmission and data-signal, video signal transmission is multi-functional unites two into one, and guaranteed better the Electro Magnetic Compatibility that power and signal transmit, also have simultaneously the functions such as low-smoke non-halogen flame-retardant, tension, mouse bite preventing and cable laying operation convenience.
A kind of protection against rodents type of the utility model CCTV special combination cable, it is characterized in that: comprise a described coaxial cable, many to separate unit data wire and power line, be cable core around the concentric stranding of coaxial cable, the wrapped surface at cable core of described polyester film, described low smoke halogen-free flame-retardant polyolefin inner sheath is extruded in the surface of polyester film, described steel wire braid is woven in the surface of low smoke halogen-free flame-retardant polyolefin inner sheath, and described protection against rodents type low smoke halogen-free flame-retardant polyolefin oversheath is extruded in the surface of steel wire braid.
Described separate unit data wire is wrapped on coaxial cable, and it is right that the separate unit data wire should be twisted into, and aluminium-plastic tape is wrapped on zinc-plated channelizing line and the right surface of line, and the low smoke halogen-free flame-retardant polyolefin external sheath layer is extruded in the surface of aluminium-plastic tape.
In described separate unit data wire and power line and be in the outer surface of the described coaxial cable of center, be provided with flexibility material filler.
The beneficial effects of the utility model are:, due to described coaxial cable of the utility model, many to separate unit data wire and power line, around the concentric stranding of coaxial cable, are cable core, formed compact conformation, and the Electro Magnetic Compatibility that has cross-talk not, do not disturb; The wrapped surface at cable core of described polyester film, described low smoke halogen-free flame-retardant polyolefin inner sheath is extruded in the surface of polyester film, form the protection to internal structure, particularly, to the protection of outside braided steel wire structure, improved again fire resistance simultaneously; Described steel wire braid is woven in the surface of low smoke halogen-free flame-retardant polyolefin inner sheath, has not only played reinforcement and protection to internal structure, and the destruction that prevents mechanical stress can prevent that again biting of muroid from causing the generation of cable short circuit or short trouble simultaneously; Described protection against rodents type low smoke halogen-free flame-retardant polyolefin oversheath is extruded in the surface of steel wire braid; namely to utilize muroid to the nature of capsaicin sensitive (muroid never bite capsicum); the physics repellant of employing environmental type muroid sensitivity-artificial capsicim; muroid is protected; have again simultaneously the low-smoke halogen-free flame-retardant sheath function, the protection internal structure is not damaged and disturbs.Because described combination cable comprises many to separate unit data wire and power line, not only can realize visualization function, can also realize simultaneously multi-line control function, the instrument of especially the terminal unregulated power being supplied, can also implement supply of electric power, be mainly the support of building subzone network supervisory control system, so can select various cable configurations numbers described in described combination cable according to user's demand, not only increased the flexibility that the utility model is selected, simultaneously also make laying installation become more simple, can realize non-maintaining.
