Abstract
The utility model discloses a kind of digital monitor system dedicated leveling pair twist UTP cables, including conductor, the conductor is coated with insulating barrier, conductor and insulating barrier formation cable insulation wire；Two thoroughly do away with edge wire stranding into insulated wire pair；Some insulated wires are to composition cable core；When for indoor type UTP cables, outer jacket is extruded on the outside of cable core；When UTP cables universal for indoor and outdoor, extruded on the outside of cable core and extrude outer jacket outside sheath, sheath.The utility model patent has the beneficial effect that：By increasing conductor, electric property is designed according to digital security monitoring system feature, have the advantages that decay surplus is big, long transmission distance, its transmission range is 3 times of same type Ethernet cable, the transmission range of cable is greatly reinforced, and do not interfere with normal lay of cable and use, solve traditional ethernet UTP cables be used for digital security monitoring system decay surplus it is small, the problem of transmission range is short.
Description
Technical field
The utility model patent is related to a kind of information transfer cable, specially a kind of digital monitor system dedicated leveling pair twist
UTP cables.
Background technology
UTP cables refer to unshielded twisted pair (Unshielded Twisted Pair, abridge UTP), are that a kind of data are passed
Defeated line, is made up of some transmission lines to different colours.UTP is wrapped up in without metal shield materials, only one layer insulating cement suitcase, valency
Lattice are relatively cheap, networking flexibility, and its circuit advantage is good flame retardation effect, it is not easy to cause fire.It is widely used in Etherloop.
With developing rapidly for digital security monitoring system in recent years, traditional ethernet standard UTP cables are increasingly popular big
Amount is applied to the occasion of the indoor and outdoors such as digital security monitoring system, this occasion have to the transmission range of electric UTP cables compared with
High requirement, and former ethernet standard UTP products, design transmission range are not far (being usually no more than 90 meters), and line is to logarithm one
As for four pairs and digital security monitoring system transmission signal only need two pairs；By traditional ethernet standard UTP cable applications in number
Word safety defense monitoring system exist transmission range do not reach digital security monitoring system requirement (typical transmission distance for 300 meters with
It is interior) situation, and exist wasting of resources situation (wire rod have four insulated wires pair and only be applicable two insulated wires to transmission signal,
Remaining two lines are to idle waste).
Utility model content
The purpose of the utility model patent is to provide for a kind of digital monitor system dedicated leveling pair twist UTP cables, with
Solve problem present in existing application and technology.
The purpose of the utility model patent is achieved through the following technical solutions.
A kind of digital monitor system dedicated leveling pair twist UTP cables, including conductor, the conductor are coated with insulating barrier,
Conductor and insulating barrier formation cable insulation wire；Two thoroughly do away with edge wire stranding into insulated wire pair；Some insulated wires are to composition
Cable core；When for indoor type UTP cables, PVC protective layers are extruded on the outside of cable core；When UTP cables universal for indoor and outdoor, cable core
Outside to extrude and extrude PE protective layers outside PVC protective layers, PVC protective layers.
Described conductor is single bare copper wire, and a diameter of 0.6mm anaerobics copper conductor greatly reduces the direct current of conductor
Resistance, adds system attenuation surplus.
Described insulated wire is to for two pairs.
The insulated wire is left-hand, pair twist as counterclockwise to pair twist direction.
Indoor type UTP cables, the sheath material is high-quality PVC plastic.Insulated wire cores are protected not damaged by external force.
The universal UTP cables of indoor and outdoor, the sheath is high-quality PVC plastic, and the oversheath closely coats sheath
On, oversheath uses high-quality PE plastics, wear-resisting, anti-aging, antiultraviolet.
The utility model patent has the beneficial effect that：By increasing conductor, set according to digital security monitoring system feature
Electric property is counted, has the advantages that decay surplus is big, long transmission distance, its transmission range is 3 times of same type Ethernet cable,
The transmission range of cable has been greatly reinforced, and has not interfered with normal lay of cable and has been used, traditional ethernet UTP has been solved
Decay surplus that cable is used for digital security monitoring system is small, the problem of transmission range is short.
Brief description of the drawings
Fig. 1 is a kind of cross-sectional view of embodiment of indoor type UTP cables.
Fig. 2 is a kind of cross-sectional view of embodiment of the universal UTP cables of indoor and outdoor.
In figure：1st, conductor 2, insulating barrier 3, PVC protective layers 4, PE protective layers.
Embodiment
The utility model patent is elaborated with reference to the accompanying drawings and examples.
A kind of digital monitor system dedicated leveling pair twist indoor type UTP cables described in Fig. 1, including conductor 1, the conductor
1 is coated with insulating barrier 2, conductor 1 and the formation cable insulation wire of insulating barrier 2；Two thoroughly do away with edge wire stranding into insulated wire pair；If
The insulated wire is done to composition cable core；PVC protective layers 3 are extruded on the outside of cable core.
A kind of universal UTP cables of digital monitor system dedicated leveling pair twist indoor and outdoor as shown in Figure 2, including conductor 1,
The conductor 1 is coated with insulating barrier 2, conductor 1 and the formation cable insulation wire of insulating barrier 2；Two thoroughly do away with edge wire strandings into exhausted
Edge line pair；Some insulated wires are to composition cable core；Extruded on the outside of cable core and PE protections are extruded outside PVC protective layers 3, PVC protective layers 3
Layer 4.
Described conductor 1 is single bare copper wire, and a diameter of 0.6mm anaerobics copper conductor greatly reduces the direct current of conductor
Resistance, adds system attenuation surplus.
Described insulated wire is to for two pairs.Designed by insulating barrier differentiation, reached characteristic impedance, return loss etc.
The stabilization of transmission characteristic.
The insulated wire is left-hand, pair twist as counterclockwise to pair twist direction.
The material of PVC protective layers 3 is high-quality PVC plastic, protects insulated wire cores not damaged by external force.
PE protective layers 4 use high-quality PE materials, wear-resisting, anti-aging, antiultraviolet.
