Anti-rodent and anti-pecking layer stranding optical cable and manufacturing method thereof

Abstract

The invention relates to an anti-rodent and anti-pecking layer stranding optical cable and a manufacturing method thereof. The anti-rodent and anti-pecking layer stranding optical cable comprises a layer stranding cable core and an external sheath. The anti-rodent and anti-pecking layer stranding optical cable is characterized in that the layer stranding cable core is externally wrapped by an armor layer which is externally wrapped by the external sheath. The external sheath comprises an external sheath internal layer and an external sheath external layer. The external sheath internal layer is a chemical rat-proof layer. The external sheath external layer is a hard high-density polyethylene layer. The anti-rodent and anti-pecking layer stranding optical cable is reasonable and simple in structural arrangement, great in flexibility and low in manufacturing cost so that the anti-rodent and anti-pecking layer stranding optical cable is anti-rodent and anti-pecking, high in protection performance and convenient to manufacture without pollution to working environment The double-cladding external sheath wraps the internal layer with rodenticide inside, and the internal and external layers are formed simultaneously in processing by adopting a co-extrusion formation mode so that volatilization of the rodenticide in the process of processing can be isolated, and environmental pollution in the process of processing can be avoided.

Description

technical field [0001] The invention relates to an anti-bite and anti-peck layer-twisted optical cable and a manufacturing method thereof, which are anti-rat bite and anti-bird peck. Background technique [0002] The optical cable used for anti-biting and pecking is to prevent the laid optical cable from biting and pecking by various rodents and some birds during use. Among them, optical cables laid on the ground will be damaged by rats, some overhead optical cables, and woodpecker birds will damage the optical cables. In the prior art, there are two types of rodent-proof methods for optical cables: physical rodent-proof and chemical rodent-proof. Physical rodent protection is mostly provided with double-layer steel strips or steel wires in the outer sheath. Not only are the materials and production costs expensive, but the optical cable is heavy, and the cable is relatively stiff, which is inconvenient for laying and maintenance. Chemical rodent protection refers to addin...

Problems solved by technology

Experiments have shown that mice are sensitive to capsicum, which is an effective rodent repellant recognized in the industry. However, since capsicum is directly added to the cable sheath, a large amount of pungent odor will be produced during the mixing and extrusion process. Pollution of the surrounding air seriously affects the normal work of production personnel and brings great inconvenience to production
