Abstract

The invention discloses a reinforced type all-dielectric and rodent-resistant cable and a manufacturing process of the reinforced type all-dielectric and rodent-resistant cable, and relates to the technical field of communication cables. The reinforced type all-dielectric and rodent-resistant cable comprises multiple optical fibers, fiber paste, a loose casing pipe, a center reinforcement piece, a cable core water-resistant compound, an inner sheath, multiple rod-shaped FRPs 7 and an outer sheath, wherein the multiple rod-shaped FRPs 7 are arranged between the inner sheath and the outer sheath; the multiple optical fibers are arranged inside the inner sheath; the loose casing pipe is arranged outside the optical fibers; the position between the optical fibers and the loose casing pipe is filled with the fiber paste; the position between the loose casing pipe and the inner sheath is filled with the cable core water-resistant compound; the center reinforcement piece is arranged in the center of the optical fibers. According to the reinforced type all-dielectric and rodent-resistant cable and the manufacturing process of the reinforced type all-dielectric and rodent-resistant cable, the weight of FRP sheathed rodent-resistant cables is reduced greatly, the difficulty of laying construction is not added under the condition that the cables have the good rodent-resistant effect, and the solution is provided for optical communications at areas with serious damage caused by rodents, such as mountainous areas and sewer lines of cities.

Description

technical field

[0001] The invention relates to the technical field of communication optical cables, in particular to a reinforced all-dielectric anti-rat optical cable and a manufacturing process thereof. Background technique

[0002] At present, there are two types of anti-rodent methods for optical cables: chemical anti-rat and physical anti-rat. Chemical anti-rat means adding a rodent repellant in a certain proportion to the outer sheath of the optical cable to achieve the purpose of rodent protection. Usually, synthetic chili is used. This rodent-proof method can make the optical cable achieve a good rodent-proof effect. The construction process will cause harm to the human body, and the spicy agent migrates and volatilizes from the sheath material in a long-term environment, so it is difficult to guarantee the rodent-proof effect and effective time of the optical cable sheath material containing the spicy agent. Physical rodent protection is armored with multi-layer s...
