Abstract

The utility model discloses a water line optical cable used for performing submarine communication transmission. The utility model adopts high strength aluminum wrapped steel wire to replace galvanized mild steel wire in the common water line optical cable, and the utility model is manufactured by squeezing and wrapping the high purity soft electrical aluminum onto the high strength steel wire, the outer layer aluminum wrapped layer has more excellent corrosion resistance performance than the galvanization layer, the strength of the steel wire is 1000 to 1600 GPa, being 2 to 3 times of the mild steel wire, therefore less aluminum wrapped steel wire can be used to reach higher tensile strength, the diameter and the weight of the optical cable are effectively reduced, and the purposes of reducing the cost and convenient transportation are achieved.

Description

The modified Water line optic cable

Relate to the field:

The utility model relates to a kind of Water line optic cable that is used for communicating transmission under water.

Background technology:

Water line optic cable is a kind of special optical cable that lays under water, requires to have good Corrosion Protection and tension, compressive property usually.Common Water line optic cable all is outside the optical cable core of armouring aluminium strip, one or more layers zinc plated mild carbon steel silk of armouring again, and the outside adds one deck PE oversheath more then.Because mild steel wire intensity is relatively low, be generally 343～490GPa, when requiring the waterline cable to reach bigger tensile property, the zinc plated mild carbon steel silk quantity that is adopted is just more relatively or steel wire diameter is relatively large, this has just increased the diameter and the weight of Water line optic cable virtually, cost is relatively just higher, returns transportation and brings certain difficulty.Because the cable footpath is bigger, therefore the sabot amount will be restricted, that is factory length can be restricted.In addition, if just in case be subjected to the destruction of accidentalia (as cast anchor, trawlnet etc.) restrictive coating is damaged, the zinc-plated anticorrosive coat of zinc plated mild carbon steel silk will be difficult to resist the erosion of water, and the corrosion of mild steel wire will be difficult to avoid.But, shape easily, so still continue again at present to use because the zinc plated mild carbon steel silk is soft.

Summary of the invention

Problem to be solved in the utility model is intended to overcome the deficiency that above-mentioned prior art exists, and a kind of follow-on Water line optic cable is provided

The technical scheme that the utility model adopted is: adopt high-intensity aluminum cald steel wire to replace zinc plated mild carbon steel silk in the common Water line optic cable.This high-intensity aluminum cald steel wire, be with highly purified soft electrician's aluminium continuously extruded be coated on the high-tensile steel wires to make form, its outer field aluminium covering has the corrosion resistance more excellent than zinc coat, and intensity of steel wire wherein is 1000～1600GPa, be 2～3 times of mild steel wire, can reach advantages of higher tensile strength with more a spot of aluminum cald steel wire like this, thereby reduce the diameter and the weight of optical cable effectively, reach and reduce cost, the purpose of being convenient to transport, simultaneously also can make the sabot length and the factory length of optical cable longer, this will mean the joint quantity that can reduce optical cable, thereby reduce the failure rate and the maintenance cost of optical cable.

Description of drawings:

Fig. 1 is the utility model waterline cable sectional view

Below in conjunction with description of drawings the concrete exemplifying embodiment of the utility model is further described below:

As shown in Figure 1, go up coating one deck PE bed course (5) at the central reinforce member (6) of optical cable, loose sleeve pipe (1) (can use gasket for packing generation part pine sleeve pipe wherein) in its peripheral layer strand Unit 5～12, can place 2～12 optical fiber (3) or fibre ribbon in the every loose sleeve pipe and fill fine ointment (2), cable ointment (4) is filled in gap between the pine sleeve pipe, the pine sleeve pipe is outward to prick yarn (7) and two-sided plastic-coated aluminium strip (8), the bonding PE inner sheath of aluminum-polyethylene (9), being the high-intensity aluminum cald steel wire of armouring (10) afterwards, is tygon oversheath (11) at last.

Claims

1, a kind of Water line optic cable is characterized in that adopting aluminum cald steel wire to replace zinc plated mild carbon steel silk in the common Water line optic cable.

2, aluminum cald steel wire according to claim 1 is characterized in that continuously extruded being coated on the steel wire of soft electrician's aluminium made.

3, aluminum cald steel wire according to claim 1 is characterized in that intensity of steel wire is 1000～1600GPa.
