Reinforced type all-dielectric and rodent-resistant cable and manufacturing process thereof

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...

Problems solved by technology

Usually the armor layer uses metal armor layer or non-metal armor layer. The metal armor layer is used because the metal texture is hard, and rodents such as mice cannot bite it. The disadvantage is that the weight is too large and the cost is high; the use of glass fiber armor Layering is because the glass fiber can hurt the mouth of rodents. The disadvantage is that the glass fiber layer of this kind of rodent-proof optical cable must be very thick, otherwise it will not be able to achieve a good rodent-proof effect.

[0004] With the implementation of the broadband China strategy, the demand for anti-rodent optical cables in urban sewer pipes and mountainous areas is also increasing. The anti-rat optical cables currently on the market either have poor anti-rat effect, heavy weight, or high cost. , so that the use and construction of the anti-rat optical cable have brought many changes
