Abstract
The utility model discloses a kind of novel three core high-strength waterproof fiber optic cables, comprise the cable core be made up of an identical cable core of volume and two strengthening cores laying respectively at the cable core left and right sides, described cable core respectively with two strengthening core co-extrusion one deck waterproof oversheaths; Described cable core extrudes the total oversheath with tongue outward again.This construction of cable is simple, it is convenient to manufacture, production cost is low, and anti-wear performance is high, by the steel wire rope of 2 outside oversheath, strengthens the intensity of whole cable, extends the useful life of cable; Total oversheath is provided with tongue, when the extruding be subject to, has a space that can alleviate, not easy to crack; Extend the useful life of cable further; This cable also has better water resistance.
Description
Technical field
The utility model belongs to power cable field, is specifically related to a kind of three core high-strength waterproof fiber optic cables.
Background technology
As everyone knows, fire-retardant and the flame resistance of cable can significance level in use, fireproof cable in the past have employed the structure such as the mineral insulations such as magnesium oxide and metallic copper sheath, due to the restriction of each side, causing can not large produced in lengths continuously, and can not bend, be not easy to mounting and installation, so there is flexible fire-proof cable, by contrast can large produced in lengths continuously, cross section is also unrestricted, there is good bending property simultaneously, mounting and installation is also very convenient, fire protecting performance is excellent, fire resistance rating not only meets the regulation in GB GB/T 19666-2005 and rower GA 306.2-2007, also can meet the A level 650 DEG C of 3h specified in Britain BS6387, B level 750 DEG C of 3h, C level 950 DEG C of 3h, the combustion requirements of S level 950 DEG C of 20min, simultaneously, water spray and mechanical impact can be tolerated in burning.
At present, along with the development of society, the speed of designed for communications cables Cheng Genggao and transmission frequency, the isolation of insulation builds
Verified is being unsuccessful by crosstalk reduction to tolerable injury level, and the known twisting of at least some is to the isolation comprised cable as shield member work, and these interlayers comprise metal insert, and these metal inserts are enclosed in the insulating element of insulation.These traditional insulating elements make and assemble costly.In addition, these shielding interlayers keep relatively thick, thus cause cable bulky, when staff is carrying out, in cable laying process, being easy to destroy outer jacket in laid processes.
In sum, the deficiency that prior art exists, flexible poor, water proofing property is poor, fire resistance is poor, is easily bent arbitrarily and draws, easily cause disconnected core in the use procedure of cable; In addition, in the case of crushing, oversheath easily ftractures.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide that a kind of flexibility is better, water-and fire-proof is good, can bend arbitrarily and draw, not easily broken core, three core high-strength waterproof fiber optic cables not easy to crack.
The novel three core high-strength waterproof fiber optic cables of one described in the utility model, comprise the cable core be made up of an identical cable core of volume and two strengthening cores laying respectively at the cable core left and right sides, cable core and strengthening core are in same level position; Described cable core is made up of conductor, insulating barrier, plastic-aluminum combined vertical covering and waterproof oversheath from inside to outside successively, is provided with an optical fiber in cable core waterproof oversheath; Two described strengthening core structures are identical, are made up of successively from inside to outside steel wire rope and waterproof oversheath; Described cable core respectively with two strengthening core co-extrusion one deck waterproof oversheaths; Described cable core extrudes the total oversheath with tongue outward again.
Further improvement, the gap of described cable core is provided with waterstop.
Further improvement, described insulating barrier is made up of multi layer cloud master tape.
Further improvement, described waterproof oversheath and total oversheath all adopt outer protective polyethylene cover.
The beneficial effects of the utility model are:
Compared with prior art, this construction of cable is simple, it is convenient to manufacture, production cost is low, and anti-wear performance is high, by the steel wire rope outside oversheath, strengthens the intensity of whole cable, extends the useful life of cable; Add one deck oversheath cable core is external, well can protect the structure of cable core, not fragile, extend further cable useful life; This cable also has better water-and fire-proof performance; In addition, use 2 strengthening cores, more can strengthen the intensity of cable, make cable core not easily broken, more firmly; Total oversheath is provided with tongue, when the extruding be subject to, has a space that can alleviate, not easy to crack; The utility model has merged the function of optical fiber communication and electric power transfer, has the features such as high reliability data is transmitted, price is low, easy to connect.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the novel three core high-strength waterproof fiber optic cables of one described in the utility model, comprise the cable core be made up of an identical cable core of volume and two strengthening cores laying respectively at the cable core left and right sides, cable core and strengthening core are in same level position; Described cable core is made up of conductor 1, insulating barrier 2, plastic-aluminum combined vertical covering 3 and waterproof oversheath 4 from inside to outside successively, is provided with an optical fiber 6 in cable core waterproof oversheath 4; Two described strengthening core structures are identical, are made up of successively from inside to outside steel wire rope 5 and waterproof oversheath 4; Described cable core respectively with two strengthening core co-extrusion one deck waterproof oversheaths 4; Described cable core extrudes the total oversheath 8 with tongue 7 outward again.
The gap of described cable core is provided with waterstop 9; Described insulating barrier 2 is made up of multi layer cloud master tape; Described waterproof oversheath 4 and total oversheath 8 all adopt outer protective polyethylene cover.
The utility model provides a kind of novel three core high-strength waterproof fiber optic cables; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
