Description

A kind of central beam tube type optoelectronic composite cable of termite-resistant rodent-resistant
Technical field
The utility model relates to composite rope, particularly a kind of central beam tube type optoelectronic composite cable of termite-resistant rodent-resistant.
Background technology
At present, photoelectric mixed cable widely uses in d. c. remote is powered, solve the loss occurred when optical fiber switch and optical transceiver utilize the-48V direct current in machine room directly to transmit large, transmission range is near, power cannot meet switch and the normal need of work of optical transceiver, subjects to the problems such as thunderbolt summer, without the need to again laying supply line, ensure that the Internet interchanger connects uninterrupted, not by all weather operations of external interference.
The photoelectric mixed cable that market generally uses is that optical fiber, transmission of electricity copper cash, copper holding wire is stranded in one, forms the optical cable of rounding, solves the problems such as broadband access, equipment electricity consumption, emergency parachute transmission simultaneously.But along with client requires more and more higher to the comprehensive each side such as efficiency of construction, security performance introducing circuit, how photoelectric mixed cable product reaches the segregative object of photoelectricity is also the focus paid close attention in the market.Existing optical cable mostly is optical fiber outer jacket sleeve pipe, and coordinates the structure of oversheath, and its mechanical performance is poor, easily go wrong during long distance bracing wire, secondly cable outer sheath adopts PE sheath usually, and its pressure-proof and snap-resistent ability is poor, once be dug or touch by mistake by mistake, be easy to occur the situations such as breakage, fracture.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides the central beam tube type optoelectronic composite cable of simple, the lightweight termite-resistant rodent-resistant of a kind of structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of central beam tube type optoelectronic composite cable of termite-resistant rodent-resistant, it comprises oversheath, the steel band be arranged in oversheath, the water blocking layer be arranged in steel band, be arranged on Loose tube in water blocking layer and cable core, interval packed layer between Loose tube and cable core, be filled with super-tensile fiber in packed layer, in oversheath, be provided with some steel wires.
Described steel band is plastic-coated steel band.
Described steel wire is provided with two, two steel wires with the axis of oversheath for line of symmetry is symmetric.
Described oversheath is nylon sheath wire.
The utility model has the following advantages:
1. by adopting nylon sheath wire, the resistance to wear of this composite rope can be improved, wearing and tearing when reducing the wearing and tearing of steel band when poling with this and lay, and can effectively prevent stinging of worm, mouse etc. from biting, improve the useful life of composite rope, and improve the pliability of optical cable, make optical cable enough adapt to complicated laying environment and have good anti-pressure measurement performance;
2. effectively can shield extraneous signal disturbing by arranging plastic-coated steel band, such that this composite rope anti-pressure ability is strong, insulation property strong, and impulse-free robustness, tube wall are smooth, wear electric wire, cable or optical fiber when being applicable to construction;
3. by filling super-tensile fiber in packed layer, this composite rope is made to have high strength, high fatigue durability, the performance such as high temperature resistant, corrosion-resistant, shock-resistant, effectively can improve the tensile strength of this composite rope, and make this composite rope have good flexibility, what can adapt to complexity when laying lays environment, when after the parts against wear outside packed layer, it is not damaged that the super-tensile fiber of filling in packed layer can continue protection cable core;
4. can improve tensile strength and the compression strength of this composite rope by arranging steel wire, this composite rope can be protected to avoid being subject to damage with this;
5. can effectively prevent cable core from making moist by arranging water blocking layer, avoiding cable core be damaged in a humid environment or leaky occurs with this.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of central beam tube type optoelectronic composite cable of termite-resistant rodent-resistant.
In figure, 1-oversheath, 2-steel wire, 3-steel band, 4-Loose tube, 5-packed layer, 6-cable core, 7-water blocking layer.
Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection range of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of central beam tube type optoelectronic composite cable of termite-resistant rodent-resistant, it comprises oversheath 1, be arranged on the steel band 3 in oversheath 1, be arranged on the water blocking layer 7 in steel band 3, be arranged on the Loose tube 4 in water blocking layer 7 and cable core 6, in the present embodiment, described oversheath 1 is nylon sheath wire, resistance to wear because nylon sheath wire has, easily bending, can be effectively antirust, the features such as non flouling behaviour alluvial, the oversheath 1 being used as this composite rope can improve the resistance to wear of this composite rope, described steel band 3 is plastic-coated steel band, interval packed layer 5 between Loose tube 4 and cable core 6, super-tensile fiber is filled with in packed layer 5, some steel wires 2 are provided with in oversheath 1, in the present embodiment, described steel wire 2 is provided with two, two steel wires 2 with the axis of oversheath 1 for line of symmetry is symmetric, steel wire 2 can guarantee the physical property that optical cable is nearly all and mechanical performance, can play a part to support in this composite rope with tension, thus make cable core exempt from external force and guarantee its stability of laying.
