Description

Technical Field

[0001] The utility model belongs to the technical field related to cables, and particularly relates to a strong overload super soft cross-linked environmental protection cable. Background Technique

[0002] In modern industrial and commercial applications, the performance of cables directly affects the stability and operating efficiency of equipment. The research and development and application of strong overload super soft cross-linked environmental protection cables emerge as the times require, aiming to meet the increasingly complex and stringent electrical environment requirements. Traditional cables often show deficiencies under high loads, frequent bending, and environmental challenges, especially in scenarios that require high flexibility and durability. This type of cable overcomes the limitations of traditional cables through the integration of multiple advanced technologies. First, the application of cross-linked polyethylene (XLPE) insulation technology significantly improves the heat resistance and insulation performance of the cable. The cross-linked polyethylene material remains stable in high-temperature environments and can effectively prevent insulation aging or breakdown problems that may occur during long-term high-load operation of the cable. Second, the super soft design enables the cable to flex flexibly in narrow spaces without affecting performance, making it very suitable for complex installation environments and applications with frequent movement. The use of environmentally friendly materials is also one of the core advantages of this cable. The use of halogen-free materials and low-smoke materials significantly reduces the harmful gases and smoke generated by the cable in the event of a fire, protecting the environment and personnel safety. The multi-layer copper foil shielding layer effectively isolates electromagnetic interference, ensuring the stability and integrity of signal transmission.

[0003] However, although the strong overload super soft cross-linked environmental protection cable performs excellently in terms of flexibility and high-load performance, its tensile strength is relatively poor. Since the cable focuses on super softness and high-load capacity in design, its tensile strength is relatively insufficient. This means that in an environment of high-intensity pulling or frequent movement, the cable may be prone to mechanical damage or breakage. In an industrial environment, especially during equipment installation and maintenance, the cable may be pulled, bent, or twisted, resulting in damage to the insulation layer or the cable conductor, thus affecting the long-term stability and safety of the cable. Content of the Utility Model

[0004] The purpose of the utility model is to provide a strong overload super soft cross-linked environmental protection cable to solve the problem that due to the cable focusing on super softness and high-load capacity in design, its tensile strength is relatively insufficient, which means that in an environment of high-intensity pulling or frequent movement, the cable may be prone to mechanical damage or breakage as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A strong overload super soft cross-linked environmental protection cable, including a cable body and a cable identification label provided on the outer wall of the cable body, wherein cable model information is provided on the cable identification label, and a tensile strength enhancing device is fixed on the outer wall of the cable body;

[0006] The described tensile strength enhancing device includes a reinforcing sleeve hole, a soft steel wire rope, and a composite rubber strip.

A reinforcing sleeve hole is arranged inside the composite rubber strip, and a soft steel wire rope is inserted into the reinforcing sleeve hole. The soft steel wire rope and the composite rubber strip are fixedly connected by a hot melting method.

[0007] Preferably, the tensile strength enhancing device further includes a reinforcing connecting strip. A plurality of reinforcing connecting strips are evenly connected between the plurality of composite rubber strips, and the reinforcing connecting strip is fixedly connected to the composite rubber strip and the cable body by heat sealing and an adhesive.

[0008] Preferably, the cable body is composed of an outer sheath, a shielding layer, a reinforcing layer, an insulating sleeve, a filling layer, and a cable conductor. A plurality of the insulating sleeves are provided, and a cable conductor is fixed in each of the plurality of insulating sleeves. A reinforcing layer is sleeved outside the plurality of insulating sleeves, and the insulating sleeve is made of cross-linked polyethylene.

[0009] Preferably, a shielding layer is sleeved outside the reinforcing layer, an outer sheath is sleeved outside the shielding layer, the composite rubber strip and the reinforcing connecting strip are both fixed on the outer wall of the outer sheath, and a filling layer is filled between the reinforcing layer and the plurality of insulating sleeves.

[0010] Preferably, the composite rubber strip and the reinforcing connecting strip have the same thickness, and the thicknesses of the composite rubber strip and the reinforcing connecting strip are both smaller than the thickness of the outer sheath.

[0011] Preferably, the shielding layer is made of multiple layers of copper foil, and the shielding layer is used to reduce electromagnetic interference and ensure signal integrity.

[0012] Preferably, the reinforcing layer is made of aramid fiber, and the outer sheath is made of polyvinyl chloride.

[0013] Compared with the prior art, the present utility model provides a strong overload super soft cross-linked environmental protection cable, which has the following beneficial effects:

[0014] The utility model adds a new enhanced tensile strength device to the outer wall of the outer sheath of the strong overload super-soft cross-linked environmental protection cable. The enhanced tensile strength device can strengthen the tensile strength of the cable through multiple composite rubber strips fixed on the outer wall of the outer sheath and soft steel wire ropes inside the composite rubber strips. As the main tensile strength component, the composite rubber strips provide excellent elasticity and toughness, which can effectively disperse and relieve the influence of the pulling force on the cable. The soft steel wire ropes fixed inside the composite rubber strips provide additional tensile strength to ensure that the cable is not easily broken or damaged when subjected to a tensile force. The combination of the composite rubber strips and the soft steel wire ropes enables the outer sheath of the cable to have stronger mechanical protection, reducing the risk of damage caused by external pulling or impact. At the same time, the enhanced connecting strips connecting multiple composite rubber strips increase the structural stability, ensuring that the cable maintains a good physical shape during use. In summary, the new enhanced tensile strength device significantly improves the tensile strength performance of the strong overload super-soft cross-linked environmental protection cable, ensuring its reliability and durability under complex and harsh conditions.

[0019] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0020] The utility model provides as Figures 1 - 3A strongly overloaded and super soft cross-linked environmental protection cable shown in the figure includes a cable body 1 and a cable identification label 2 provided on the outer wall of the cable body 1. Cable model information is set on the cable identification label 2. The cable body 1 is jointly composed of an outer sheath 4, a shielding layer 5, a reinforcing layer 6, an insulating sleeve 7, a filling layer 8, and a cable conductor 9. There are multiple insulating sleeves 7, and cable conductors 9 are fixed in each of the multiple insulating sleeves 7. A reinforcing layer 6 is sleeved outside the multiple insulating sleeves 7. The insulating sleeve 7 is made of cross-linked polyethylene, which has excellent heat resistance, insulation strength, and chemical stability. The cross-linking treatment improves its temperature resistance and long-term stability to ensure the safe insulation of the cable conductor 9, avoid leakage and short circuit, and is suitable for high-temperature and high-load environments. A shielding layer 5 is sleeved outside the reinforcing layer 6, and an outer sheath 4 is sleeved outside the shielding layer 5. A composite rubber strip 12 and a reinforcing connection strip 13 are both fixed on the outer wall of the outer sheath 4. A filling layer 8 is filled between the reinforcing layer 6 and the multiple insulating sleeves 7. The filling layer 8 is usually used to enhance the structural stability of the cable and prevent the cable from deforming when bent or moved, so as to maintain the shape stability of the cable and reduce the risk of damage caused by bending or stretching. The composite rubber strip 12 and the reinforcing connection strip 13 have the same thickness, and the thicknesses of the composite rubber strip 12 and the reinforcing connection strip 13 are both smaller than the thickness of the outer sheath 4.

[0021] As Figure 1 and Figure 2 shown, the shielding layer 5 is made of multiple layers of copper foil. The shielding layer 5 is used to reduce electromagnetic interference and ensure the integrity of signals. The multi-layer copper foil shielding provides excellent electromagnetic interference protection, reduces the interference of external electromagnetic waves on the cable transmission signal, and ensures the integrity and stability of signal transmission, especially in applications where high-frequency or sensitive signals are transmitted. The reinforcing layer 6 is made of aramid fiber, which has extremely high strength and heat resistance and can provide additional mechanical protection and enhance the tensile resistance of the cable. This can improve the tensile strength and durability of the cable, especially performing excellently in high-load and frequently moving applications. The outer sheath 4 is made of polyvinyl chloride, which has excellent wear resistance, chemical corrosion resistance, and mechanical strength. It can effectively protect the internal layers from physical damage, chemical erosion, and environmental factors. The polyvinyl chloride outer sheath 4 can extend the service life of the cable and maintain the stability and reliability of the cable in various application environments.

[0022] As Figure 1 and Figure 3As shown, a tensile strength reinforcement device 3 is fixed to the outer wall of the cable body 1. The tensile strength reinforcement device 3 includes a reinforcement sleeve hole 10, a soft steel wire rope 11, and a composite rubber strip 12. There are multiple composite rubber strips 12, and the multiple composite rubber strips 12 are equidistantly fixed on the circular outer wall of the cable body 1. The composite rubber strip 12 has good elasticity and toughness, and can effectively disperse and relieve the pulling force to reduce the influence of the external pulling force on the cable body 1, and avoid damage or breakage of the cable caused by the pulling force. A reinforcement sleeve hole 10 is arranged inside the composite rubber strip 12, and a soft steel wire rope 11 is inserted into the reinforcement sleeve hole 10. The soft steel wire rope 11 placed inside the composite rubber strip 12 provides additional tensile strength and stability, which can significantly improve the tensile strength of the cable, ensure the stability of the cable when stressed, and avoid damage caused by excessive pulling force. The soft steel wire rope 11 and the composite rubber strip 12 are fixedly connected by a hot melting method. The hot melting fixing method ensures the firm combination of the soft steel wire rope 11 and the composite rubber strip 12, enhances the overall stability of the tensile strength reinforcement device, and provides stronger connection strength and durability, preventing the device from loosening or falling off during use. The tensile strength reinforcement device 3 further includes a reinforcement connecting strip 13. A plurality of reinforcement connecting strips 13 are equidistantly connected between the multiple composite rubber strips 12, and the reinforcement connecting strips 13 are fixedly connected to the composite rubber strips 12 and the cable body 1 by heat sealing and an adhesive. The reinforcement connecting strip 13 is used to connect the multiple composite rubber strips 12, enhances the stability of the overall structure, ensures the uniform force distribution between the composite rubber strips 12, and further improves the tensile strength and overall strength of the cable.
