Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a tensile-resistant and breakage-resistant power cable. Background Technology

[0002] Cables are electrical lines used to transmit electrical energy, signals, or convert electromagnetic energy, and are widely used in power systems, communication networks, industrial automation, building wiring, and other fields.

[0003] Existing cables are prone to conductor breakage or overall cable structure deformation when exposed to high tensile stress, which can easily lead to signal transmission interruption or electrical faults, affecting the operational safety and efficiency of equipment, and even causing safety accidents such as power outages and signal interruptions, increasing maintenance and replacement costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tensile-resistant and breakage-resistant power cable. Through the double protection of the inner and outer protective layers, the tensile strength and structural strength of the cable can be effectively improved. When the cable faces high tensile environments, it is difficult for conductors to break or the overall cable structure to deform, thus extending the service life of the cable and making power transmission more stable and safe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensile-resistant and breakage-resistant power cable, comprising: a conductor, an inner protective layer provided on the outer wall of the conductor, a supporting skeleton provided on the outer wall of the inner protective layer, an outer protective layer provided on the outer wall of the supporting skeleton, the inner protective layer comprising a tensile-resistant braided sleeve, an aramid-filled sleeve bonded to the outer wall of the tensile-resistant braided sleeve, an insulating sleeve bonded to the outer wall of the aramid-filled sleeve, and a shielding sleeve bonded to the outer wall of the insulating sleeve. The tensile-resistant braided sleeve is made of high-strength fiber material. When the tensile-resistant braided sleeve and the aramid-filled sleeve are subjected to force, the high toughness of the high-strength fiber and the buffering effect of the filling material can absorb the force and reduce the impact of external force on the conductor.

[0006] Preferably, the outer wall of the conductor is bonded to the inner wall of the tensile braided sleeve, and the outer wall of the shielding sleeve is bonded to the inner wall of the support frame. The tensile braided sleeve is made of high-strength fiber material, and the shielding sleeve is bonded to the support frame, which further improves the structural strength of the cable.

[0007] Preferably, the outer protective layer includes a buffer protective sleeve, the outer protective sleeve is bonded to the outer wall of the buffer protective sleeve, and reinforcing ribs are slidably connected to the inner wall of the outer protective sleeve. The outer protective sleeve is made of elastic rubber, the buffer protective sleeve is made of rubber, and the support frame is made of polypropylene. By setting the outer protective layer, the tensile force on the cable is first dispersed and transmitted to the support frame, thereby reducing the force on the support frame.

[0008] Preferably, the outer protective sleeve is spirally wound around the outer wall of the buffer protective sleeve, and the inner wall of the buffer protective sleeve is bonded to the outer wall of the support frame. The spiral design of the outer protective sleeve can increase the friction of the cable and reduce the tension caused by the cable sliding during use.

[0009] Preferably, the reinforcing ribs are arranged in a ring around the central point of the supporting frame. The ring array of reinforcing ribs can resist the deformation of the outer protective layer from multiple directions, making it difficult for the outer protective sleeve to break.

[0010] This utility model provides a tensile-resistant and breakage-resistant power cable. It has the following beneficial effects: 1. The double protection of the inner and outer protective layers effectively improves the tensile strength and structural strength of the cable, making it less prone to conductor breakage or overall structural deformation when facing high tensile environments, thus making power transmission more stable and safer.

[0011] 2. The spiral design of the outer protective sleeve increases the friction of the cable and reduces the tension caused by slippage during use. At the same time, the ring array of reinforcing ribs can resist the deformation of the outer protective layer from multiple directions, making the outer protective sleeve less prone to breakage and extending the service life of the cable.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] Please see Figure 1-3This utility model provides a technical solution: a tensile-resistant and breakage-resistant power cable, comprising: a conductor 1, an inner protective layer 2 provided on the outer wall of the conductor 1, a support frame 3 provided on the outer wall of the inner protective layer 2, and an outer protective layer 4 provided on the outer wall of the support frame 3. Through the double protection of the inner protective layer 2 and the outer protective layer 4, the tensile strength and structural strength of the cable are effectively improved, making the power transmission of the cable more stable and safe.

[0016] The inner protective layer 2 includes a tensile braided sleeve 20, an aramid-filled sleeve 21 bonded to the outer wall of the tensile braided sleeve 20, an insulating sleeve 22 bonded to the outer wall of the aramid-filled sleeve 21, a shielding sleeve 23 bonded to the outer wall of the insulating sleeve 22, the outer wall of the conductor 1 bonded to the inner wall of the tensile braided sleeve 20, and the outer wall of the shielding sleeve 23 bonded to the inner wall of the support frame 3. When tensile force is applied to the tensile braided sleeve 20 and the aramid-filled sleeve 21, the high toughness of the high-strength fiber and the buffering effect of the filling material will absorb and reduce the impact of tensile force on the conductor 1.

[0017] The outer protective layer 4 includes a buffer protective sleeve 40, an outer protective sleeve 41 is bonded to the outer wall of the buffer protective sleeve 40, and a reinforcing rib 42 is slidably connected to the inner wall of the outer protective sleeve 41. The outer protective sleeve 41 is spirally wound around the outer wall of the buffer protective sleeve 40, and the inner wall of the buffer protective sleeve 40 is bonded to the outer wall of the support frame 3. The reinforcing rib 42 is arranged in a ring around the central point of the support frame 3. Through the spiral design of the outer protective sleeve 41 and the ring array of the reinforcing rib 42, the tensile strength and structural strength of the cable are effectively improved.

[0018] Working principle In use, the inner protective layer 2 provides higher tensile strength support for the conductor 1, and the outer protective layer 4 further enhances the overall structural strength and impact resistance of the cable, making it difficult for the conductor 1 to break or for the overall cable structure to deform.

[0019] When the cable faces a high-tensile environment, the tension is initially applied to the outer protective sleeve 41. Since the outer protective sleeve 41 is made of elastic rubber and is spirally wound around the outer wall of the buffer protective sleeve 40, its own material toughness and spiral structure disperse the tension. Simultaneously, the reinforcing rib 42 directly resists external forces, preventing the outer protective sleeve 41 from deforming or breaking too quickly. Subsequently, the tension is transferred from the outer protective sleeve 41 to the buffer protective sleeve 40. Because the buffer protective sleeve 40 is made of rubber, it further absorbs the tension from the outer protective sleeve 41. The tensile force is transmitted to the support frame 3, which is made of polypropylene and is not easily broken under stress. The support frame 2 can then distribute the tensile force in the circumferential direction to the entire cable cross-section to avoid local overload. This tensile force is distributed to the shielding sleeve 23 and the insulating sleeve 22, and then to the tensile braided sleeve 20 and the aramid filler sleeve 21. Since the tensile braided sleeve 20 is made of high-strength fiber, it absorbs residual external force by utilizing the high toughness of the high-strength fiber and the buffering effect of the filler material, preventing the inner protective layer 2 from delaminating. This further reduces the tensile force acting on the conductor 1, making it difficult for the conductor 1 to break or for the overall cable structure to deform.
