Description

A kind of cable core armouring lead is directly put type photoelectricity mixing cable

Technical field

The utility model relates to the optical cable technology field, and it is that a kind of cable core armouring lead is directly put type photoelectricity mixing cable in definite saying.

Background technology

At present, in Communication in China, computerized information industrial field, unification of three nets or even four networks one platform are one of the most popular topics.So-called unification of three nets is exactly that existing traditional electrical letter net (PSTN), computer network and television network broadcast are merged mutually, form a unified network system gradually, comprise the communicating by letter of all business of data, speech and image by the network facilities support of a total digitalization.And " four networks one platform " is also referred to as " 1+3 " technical scheme.1 expression electric transmission network, 3 is exactly three kinds of networks of above-mentioned " unification of three nets ".Certainly, the purpose of unification of three nets or four networks one platform is after several nets merge, and can provide lower price and more efficient, more diversified and service more easily to users, can realize the strategic interests of country again.In this sense, three nets or four networks one platform are our more satisfactory networks.Therefore, unification of three nets is before for many years and even now all praised highly by vast technical specialist.In order to realize this latticed form, will use the cable that is fit to this network, bandwidth becomes a bottleneck of common cable.

The involved optoelectronic composite cable of unification of three nets or four networks one platform, optoelectronic composite cable is applicable in the broadband access network system makes transmission line, be a kind of novel access way, its light harvesting fibre, transmission of electricity copper cash can solve the problem of broadband access, equipment electricity consumption, signal transmission in one.Its advantage is: external diameter is little, and is in light weight, and it is little to take up room.

Common optoelectronic composite cable generally adopts the loose sleeve layer strand type structure, can guarantee the optical cable characteristic, can satisfy electricity needs again, if but on the engineering between local side and the far-end power supply distance far away, when the bigger need of voltage were used than the large size copper line, just there was certain drawback in layer-twisted type structured light photoelectric compound cable; Sleeve pipe is with other twisting element external diameters and with regard to corresponding increasing, so purchase cost is higher concerning the client when producing than the large size copper line; In the stranded process of cable core stranding, exist stranded external diameter wayward, stranded dislocation, the reinforcement phenomenon product that happens occasionally that leaks outside of crossing; To such an extent as to behind the vertical bag of armouring, copper conductor insulating sleeve layer is impaired easily to cause electric leakage; Cause the unequal hidden danger of external diameter behind the sheath simultaneously.

Summary of the invention

The purpose of this utility model provides a kind of cable core armouring lead and directly puts type photoelectricity mixing cable, can overcome deficiency of the prior art, saved the operation of the stranded stranding of copper conductor aborning, not only save the utilization of copper conductor, and greatly reduce the probability of happening of copper cash insulating barrier disrepair phenomenon, improved qualification rate and the coefficient safe in utilization produced.Cancelled the vertical bag of metal compound belt armouring of copper conductor simultaneously,, so just reduced the characteristic property that material cost has guaranteed optical cable again to a great extent only at the enterprising row metal composite belt longitudinal of cable core bag.Realize remote power feeding, photoelectricity one, and optimized structure, simplify production process, reduce product cost.

The technical scheme that the utility model technical solution problem is adopted is: optical fiber surface applies the printing ink that one deck has the protection optical fiber of color; carry out the protection of pine cover then and do packaged tube; in sleeve pipe, charge into simultaneously presumable filler; through stranded sleeve pipe and presumable gasket for packing and metal reinforcement are made cable core; again cable core is carried out the vertical bag of metal compound belt; the vertical bag of cable core back utilizes the polyester band wrapped with the copper conductor that protects insulating barrier, wrappedly carries out oversheath after together, makes the finished product cable.

The advantage of this structure:

1, external diameter is little, and is in light weight, takes up room little (generally the serial problem that could solve with many cables can replace with a composite rope at this);

2, adopt optical fiber and band structure to provide huge bandwidth to insert; Can satisfy long Distance Transmission, also sectional uses;

3, the physical characteristic that still keeps optical cable is as anti-collapse, stretching etc.;

4, client's purchase cost is low, and operating expenses is low, and the networking expense is low;

5, have superior bending property and good anti-side pressure performance, easy construction;

6, provide multiple transmission technology simultaneously, strong with adaptability height, the extensibility of equipment, product is widely applicable;

7, save cost, optical fiber as the usefulness of reserving to the family, has been avoided the secondary wiring;

8, solve equipment electrical problem (avoiding repeating to lay supply line) in the networking.
