Abstract
The utility model discloses a protection against rodents prevents light -duty layer stranded type optoelectrical composite cable of ant, it includes oversheath (4), the setting in oversheath (4) inner sheath (2) and install a plurality of pine sleeve pipe (1) in inner sheath (2), one of them pine sleeve pipe (1) installs inside has optic fibre (3), be equipped with in in addition loose sleeve pipe (1) copper conductor (5), leave between pine sleeve pipe (1) and optic fibre (3) and between pine sleeve pipe (1) and copper conductor (5) filling layer (6), filling layer (6) intussuseption is filled with superstrong pulling force fibre. The beneficial effects of the utility model are that: this complex cable can be used for laying optical cable and cable simultaneously to it has light in weight, convenient transportation, corrosion -resistant, high temperature resistant, resistant stinging such as bites at the advantage.
Description
Technical field
The utility model relates to composite rope, particularly a kind of light-duty layer stranded optical/electrical 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 light-duty layer stranded optical/electrical 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 light-duty layer stranded optical/electrical composite cable of termite-resistant rodent-resistant, it comprises oversheath, is arranged on the inner sheath in oversheath and is arranged on several Loose tube in inner sheath, one of them Loose tube is built with optical fiber, other Loose tube is built with copper conductor, leave packed layer between Loose tube and optical fiber and between Loose tube and copper conductor, in packed layer, be filled with super-tensile fiber.
Described copper conductor is that SZ type twists together.
Described oversheath is made up of polymeric liquid crystal copolymer.
The utility model has the following advantages:
1. the oversheath by using polymeric liquid crystal copolymer to make, this composite rope is made to have high temperature resistant, corrosion-resistant, anti abrasive performance, when laying at the bottom of ground, due to its corrosion-resistant, anti abrasive performance, this composite rope useful life is improved, and worm, mouse etc. can be prevented to sting bite;
2. 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 oversheath breakage, the super-tensile fiber of filling in packed layer can continue protection optical fiber and copper conductor not damaged;
3. copper conductor is that SZ type twists together and copper conductor effectively can be prevented to be separated thus cause electric power transfer unstable, and facilitates copper conductor to load in Loose tube;
4. the composite rope of each unit length is lightweight, is easy to transport, lays.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of light-duty layer stranded optical/electrical composite cable of termite-resistant rodent-resistant.
In figure, 1-Loose tube, 2-inner sheath, 3-optical fiber, 4-oversheath, 5-copper conductor, 6-packed 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 light-duty layer stranded optical/electrical composite cable of termite-resistant rodent-resistant, it comprises oversheath 4, several Loose tube 1 being arranged on the inner sheath 2 in oversheath 4 and being arranged in inner sheath 2, in the present embodiment, described oversheath 4 is made up of polymeric liquid crystal copolymer, due to polymeric liquid crystal copolymer thermal stability, thermal endurance, chemical proofing, weatherability, radiation resistance is good, has excellent anti-flammability, can knock down the flame and no longer proceed burning, and have excellent electrical insulation capability, its dielectric strength is higher than common engineering plastics simultaneously, and arc resistance is good, therefore, it is possible to available protecting composite rope can not be shocked by electricity, the situations such as fire affect its serviceability, and can effectively prevent by worm due to wear-resistant, mouse etc. sting and bite, one of them Loose tube 1 is built with optical fiber 3, other Loose tube 1 is built with copper conductor 5, in the present embodiment, described copper conductor 5 twists together in SZ type, leave packed layer 6 between Loose tube 1 and optical fiber 3 and between Loose tube 1 and copper conductor 5, in packed layer 6, be filled with super-tensile fiber, because super-tensile fiber has high strength, high fatigue durability, corrosion resistance, non-conductive, low ductility, height rubs number, the excellent properties such as thermal endurance and flexibility, for being filled in composite rope, effectively can improving the performance of composite rope, enabling tension, high temperature resistant, corrosion-resistant, and there is enough flexibilities to adapt to complicated lay landform.
