Abstract

A repeater type photoelectric composite cable for a metal armouring wire has a structure similar to that of a common photoelectric composite cable and consists of an optical fiber, a PBT (polybutylece terephthalate) sleeve, a polyester belting, a copper wire, a metal reinforcing part, an insulated protective sheathing material, a plastic coated metal composite belt and a PE (polyethylene) protective sheathing material; oil ink with a color for protecting the optical fiber is coated on the surface of the optical fiber; the optical fiber is sheathed into a loose sleeve made of PBT; the loose sleeve surrounds the metal reinforcing part to be twisted into a cable core; the loose sleeve, the metal reinforcing part and the copper wire are wrapped by the polyester belting; the metal composite belt is armored at the outer layer; and a PE protective sleeve is sheathed at the outermost layer. A plurality of single-core copper wires or a soft copper stranded wire can be adopted as an element to provide power source in a long scope; the optical fiber with high quality can guarantee the wideband signal transmission; the problems in the application occasions such as a remote unattended machine room, a district machine room, a mobile station, a user access and the like can be solved; equipment can be accessed directly; and the photoelectric synchronous transmission can be realized.

Description

The metal 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 metal 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.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 and other twisting element external diameters are 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 metal armouring lead and directly puts type photoelectricity mixing cable, can overcome deficiency of the prior art, saved the consumption of copper conductor, greatly reduce the probability of happening of copper cash insulating barrier disrepair phenomenon, improved qualification rate and the coefficient safe in utilization produced, improved production efficiency simultaneously and reduced product cost.

The technical scheme that the utility model technical solution problem is adopted is: optical fiber surface applies the ink lay that one deck has the protection optical fiber of color; optical fiber is inserted in the loose sleeve pipe that PBT makes; in the pine sleeve pipe filler is arranged; copper stranded conductor and loose sleeve pipe (and gasket for packing) are twisted into cable core around central reinforce member; utilize polyester band 4 wrapped cable core and the copper conductor that protects insulating barrier again; wrapped waterstop 9 and the vertical bag of metal compound belt 10 armourings of carrying out after together, last oversheath is made 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.
