Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulating tape technology, and in particular to an insulating tape for communication cables. Background Technology
[0002] Communication cables play a crucial role in various communication systems, especially in high-frequency and long-distance signal transmission. To ensure the stable operation of communication cables in different environments, protecting them with insulating tape is essential. Insulating tape not only effectively prevents current leakage and ensures electrical safety, but also provides physical protection against cable damage caused by external factors. As the communication industry places increasingly higher demands on cables, particularly in terms of environmental adaptability and cable durability, traditional insulating tape can no longer meet these high standards. To address these challenges, more advanced insulating tapes have been developed, providing more efficient protection and ensuring the long-term stable operation of communication cables in harsh environments.
[0003] Traditional communication cable insulation tapes are typically made of a single insulating material, such as PVC or PE, designed to prevent current leakage and protect cables from physical damage. While these tapes generally possess a certain level of insulation and mechanical strength during application, their performance gradually deteriorates due to external factors such as ultraviolet radiation, moisture, and tensile stress. To enhance cable insulation and water resistance, some tapes employ a multi-layered structure, including a waterproof layer and a base insulation layer, to provide better protection. The design principle of these tapes utilizes the electrical insulation properties of the material to prevent short circuits or current leakage, while employing a reinforced mechanical structure to withstand external pressure or tension.
[0004] However, traditional communication cable insulation tapes have certain drawbacks. Especially when exposed to sunlight for extended periods, the tape is susceptible to UV radiation and denaturation, leading to a gradual decline in its insulation and waterproofing properties. This aging process not only reduces the tape's lifespan but also increases the risk of electrical failures caused by external factors. The structure and materials of traditional tapes are insufficient to withstand the long-term damage from UV radiation, limiting their application in demanding environments and making it difficult to meet the high standards of durability and performance required in modern communications. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an insulating tape for communication cables, which aims to improve the problem that the insulating tape is easily deformed by sunlight and ultraviolet rays, resulting in a decrease in its waterproof and insulating properties.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 and Figure 2This utility model provides an embodiment of an insulating tape for communication cables, comprising a roll 1, a tape body 2 disposed on the outer wall of the roll 1, a reinforcing layer 5 disposed inside the tape body 2, an anti-ultraviolet layer 4 fixedly connected to the top of the reinforcing layer 5, a protective layer 3 fixedly connected to the top of the anti-ultraviolet layer 4, a basic insulation layer 6 fixedly connected to the bottom of the reinforcing layer 5, a waterproof layer 7 fixedly connected to the bottom of the basic insulation layer 6, and an adhesive layer 8 fixedly connected to the bottom of the waterproof layer 7. The tape body 2 is composed of the protective layer 3, the anti-ultraviolet layer 4, the reinforcing layer 5, the basic insulation layer 6, the waterproof layer 7, and the adhesive layer 8. The reinforcing layer 5 is used to increase the tensile strength of the tape, enhance its durability and tear resistance, effectively resist external tension or compression, and prevent the tape from breaking due to external forces during use. The anti-ultraviolet layer 4 is used to protect the cable from the effects of ultraviolet rays in sunlight, reduce the damage of ultraviolet radiation to the tape, prevent the tape from aging, deteriorating, or degrading due to long-term exposure to sunlight, thereby extending the service life of the tape. The protective layer 3 protects the tape body 2 from physical damage, providing additional mechanical protection and preventing the tape from breaking when it comes into contact with hard objects or is subjected to friction, ensuring its stability and reliability in harsh environments. The base insulation layer 6 provides electrical insulation protection, ensuring the tape effectively prevents current leakage, prevents short circuits in the cable, and improves the electrical safety of the cable. The waterproof layer 7 prevents moisture, humidity, or other liquids from entering the cable, avoiding electrical faults or corrosion caused by moisture infiltration, and protecting the cable's stable operation in humid environments. The adhesion layer 8 adheres to the communication cable, ensuring the tape firmly adheres to the cable surface during use and preventing the tape from losing its protective function due to loosening.
[0027] Reference Figure 3 The reinforcing layer 5 has transverse warp threads 9 inside, and longitudinal warp threads 10 on the outer wall of the transverse warp threads 9. The transverse warp threads 9 and longitudinal warp threads 10 are arranged in a crisscross pattern. The diameter of both the transverse warp threads 9 and longitudinal warp threads 10 is 0.1mm. The transverse warp threads 9 are used to increase the transverse tensile strength of the reinforcing layer 5, ensuring that the tape can withstand horizontal tension or compression without easily breaking. The longitudinal warp threads 10 mainly improve the tensile strength of the tape in the longitudinal direction, preventing the tape from breaking or being damaged due to longitudinal pulling during use. The crisscrossing structure of the transverse warp threads 9 and longitudinal warp threads 10 effectively enhances the overall tensile strength of the tape, allowing the tape to distribute tension evenly and avoiding excessive stress concentration in any one direction, thereby improving the durability and reliability of the tape. The diameter of both is 0.1mm, ensuring that the weave structure of the reinforcing layer 5 is tight and stable, effectively improving the overall strength and compressive strength of the tape, and preventing damage to the surface or structure of the tape due to external factors.
[0028] Working principle: When using this communication cable insulating tape, the tape body 2 is composed of a protective layer 3, an anti-UV layer 4, a reinforcing layer 5, a basic insulation layer 6, a waterproof layer 7, and an adhesive layer 8. The reinforcing layer 5 mainly increases the tensile strength, abrasion resistance, and tear resistance of the tape, and is made of aramid fiber material. The protective layer 3 is used to resist physical damage, such as friction and impact, and uses materials such as PVC, PE, and polyurethane. The anti-UV layer 4 effectively protects the cable from the ultraviolet radiation in sunlight, extending the service life of the tape, and uses materials such as polyvinyl chloride (PVC) and polyolefins. The basic insulation layer 6 provides basic electrical insulation. The cable is protected against current leakage or short circuits using materials such as PVC, polyethylene, and rubber. The waterproof layer 7 is used to prevent moisture, humidity, or other liquids from entering the cable, especially in outdoor or humid environments. It uses waterproof materials such as rubber, thermoplastic elastomers, and asphalt. The adhesive layer 8 ensures that the tape adheres firmly to the communication cable and will not fall off due to external forces or environmental factors. It is made of pressure-sensitive adhesive. The reinforcing layer 5 includes transverse warp 9 and longitudinal warp 10, which are woven together in a crisscross pattern to improve the tensile strength of the tape body 2. Both the transverse warp 9 and longitudinal warp 10 are made of aramid fibers.
