Full dielectric layer twisted glass fiber band nylon optical cable resistant to thunder, mice and ants, and manufacturing method thereof

Abstract

The invention discloses a full dielectric layer twisted glass fiber band nylon optical cable resistant to thunder, mice and ants. The cable comprises at least one tight sleeve fiber, a central reinforcement member (2), filling ropes (3), an inner protective layer (7), a glass fiber band (8) and an outer protective layer (9). The tight sleeve fiber comprises a fiber (1), a loose sleeve pipe (6) and fiber paste (5), wherein the fiber (1) is disposed inside the loose sleeve pipe (6), and the fiber paste (5) fills between the fiber (1) and the loose sleeve pipe (6). All the tight sleeve fibers, the central reinforcement member (2) and the filling ropes (3) are disposed inside the inner protective layer (7). Water-resisting ointment (4) fills inside the inner protective layer (7). The glass fiber band (8) and the outer protective layer (9) sequentially wrap the inner protective layer (7). The outer protective layer (9) includes a polyethylene layer and a nylon layer from inside to outside. The optical cable, which is of a full dielectric structure, has great thunder and heavy current shielding properties, and is highly safe and practical.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to an all-dielectric stranded glass fiber ribbon nylon lightning-proof, mouse-proof and ant-proof cable and a manufacturing method thereof. Background technique [0002] With the continuous development of optical network technology, it has become an irreversible trend to implement optical input and copper retreat at the access level of the communication network. Due to the particularity of the laying environment of the optical cable used in the access network, due to poor grounding, the optical cable is introduced into the lightning and damages the communication. Device timing happens from time to time. Although the traditional non-metallic optical cable is also full-dielectric, it does not have the function of preventing rodents and termites. It often occurs that several bites damage the optical cable, and the optical cable is heavy and has a large outer diameter, which is c...

AI Technical Summary

Problems solved by technology

Although the traditional non-metallic optical cable is also full-dielectric, it does not have the function of preventing rodents and termites. The phenomenon of several bites and damage to the optical cable often occurs, and the optical cable is heavy and has a large outer diameter. It is also convenient for construction and has potential safety hazards.

[0003] At present, the sheath is produced by a single extruder in China, that is to say, only one raw material can be processed in one production

In this way, the inner layer is made of high-density PE, and the outer layer is made of nylon sheath, which is less efficient. It must be done twice to complete the sheath, and two times of processing is bound to cause more problems.
