Problems solved by technology

[0006] 1) The stainless steel belt is used to prevent mice. Since the base belt is made of stainless steel, it is relatively high compared to ordinary steel, which is more than 3 times the price of ordinary steel. It is difficult for users to accept and the promotion degree is poor.
[0007] 2) Extruding a layer of nylon on the outside of the PE sheath, the cost is also high and the process is complicated

Embodiment 1

[0042] The present embodiment provides a kind of manufacturing method of anti-rat optical cable, such as figure 1 or 2, including:

[0043] The rodent-proof optical cable is PE sheath 1 and nylon-coated steel belt 2 from the outside to the inside. The nylon-coated steel belt 2 is provided with a central reinforcement 5, a number of filling ropes 6 and the cable core, and the inner wall of the nylon-coated steel belt 2 is Coated with cable paste 3 , the cable core includes a loose tube 41 and a colored optical fiber 43 inside the loose tube 41 , and the loose tube 41 is also filled with fiber paste 42 .

[0044] The method specifically includes the following steps:

[0045] S1: coloring the optical fiber;

[0046] S2: Sleeve a number of colored optical fibers with loose tubes;

[0047] S3: Stranding the loose tube, central reinforcement and filling rope;

[0048] S4: Nylon-coated steel strips are installed on the loose tubes, central reinforcements and filling ropes after s...

Embodiment 2

[0052] A method for manufacturing an anti-rat optical cable, comprising the following steps:

[0053] S1: coloring the optical fiber;

[0054] S2: Sleeve a number of colored optical fibers with loose tubes;

[0055] S3: Stranding the loose tube, central reinforcement and filling rope;

[0056] S4: Nylon sheathing is provided on the loose tube, central reinforcement and filling rope sheath after stranding

[0057] Membrane steel belt;

[0058] S4: A polyethylene sheath is placed outside the nylon-coated steel belt.

[0059] The nylon coated in the nylon-coated steel belt is nylon 1010, and the outer diameter after stranding is R. In the step S4, the inner diameter of the pipe formed by the nylon-coated steel belt is 1.5%-2% R, and then after cooling, the nylon coated steel belt is clamped. For example, heating to about 80°C makes the nylon-coated steel belt first expand, then shrinks and cools down, so that the nylon-coated steel belt clamps the inner loose tube, central r...

Embodiment 3

[0064] This embodiment provides a rat-proof optical cable, which is prepared by the method for manufacturing the rat-proof optical cable described in Embodiment 1 or 2.

Abstract

The invention relates to a manufacturing method of a rat-proof optical cable and the obtained rat-proof optical cable, the rat-proof optical cable directly uses a film-coated steel belt, so that the process procedures are reduced, and the process is simpler. The surface of a conventional steel belt is coated with a nylon material, the lubricating effect is improved, a PE sheath can be convenientlyarranged outside the steel belt in a sleeving mode, and meanwhile the nylon material is coated to enable the common steel belt to achieve the rust-proof effect. The bonding strength of the common steel belt and the nylon covering film is guaranteed, and the covering film can achieve a good rat-proof effect.

Description

technical field [0001] The application belongs to the technical field of optical cable preparation, and in particular relates to a method for manufacturing an anti-rat optical cable and the obtained anti-rat optical cable. Background technique [0002] At present, the new manufacture of anti-rat optical cable by optical cable manufacturers mainly includes the following types: [0003] 1) Optical fiber coloring→secondary plastic coating→loose tube cable stranding→stainless steel tape polyethylene sheath; [0004] 2) Optical fiber coloring→secondary plastic coating→loose tube cable stranding→steel polyethylene sheath+nylon sheath; [0005] These two methods have the following disadvantages: [0006] 1) The stainless steel belt is used to prevent mice. Since the base belt is made of stainless steel, it is relatively high compared to ordinary steel, which is more than 3 times the price of ordinary steel. It is difficult for users to accept and the promotion degree is poor. ...
