Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically a composite cable for new energy power distribution equipment that is resistant to torsion and tension. Background Technology

[0002] With the acceleration of the global energy transition and the rapid development of the new energy industry, new energy power distribution equipment is playing an increasingly crucial role in energy transmission and distribution. This equipment covers numerous fields such as wind power, photovoltaics, and new energy vehicle charging stations, placing higher demands on cable performance.

[0003] Traditional cables typically use stranded metal conductors. Under prolonged torsional and tensile forces, these conductors are prone to torsional deformation, leading to increased resistance and affecting the cable's conductivity. When the deformation exceeds a certain level, the conductor may even break, causing equipment malfunctions and disrupting the normal operation of new energy equipment.

[0004] Based on this, a composite cable for new energy power distribution equipment that is resistant to torsion and tension is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of this invention is to provide a composite cable for new energy power distribution equipment that is resistant to torsion and tension, so as to solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A composite cable for new energy power distribution equipment that is resistant to torsion and tension includes a composite conductor and a composite protective sleeve. The composite protective sleeve is fitted on the outside of the composite conductor. The composite conductor includes a spirally stranded wire with an axial reinforcing core in the middle. The axial reinforcing core is made of untwisted stranded plastic-coated steel wire. The composite protective sleeve includes an inner layer, a middle layer and an outer layer, with the middle layer located between the inner layer and the outer layer.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the conductor comprises pre-deformed soft copper wire spirally stranded, and the outer side of the conductor is covered with silver-plated copper-clad steel reinforcing wire.

[0008] In one alternative: the diameter of a single pre-deformed soft copper wire is ≤0.2mm, and the stranding pitch ratio is 6-8 times.

[0009] In one alternative: the stranding direction of the silver-plated copper-clad steel reinforcing wire is consistent with the stranding direction of the conductor.

[0010] In one alternative: the inner layer is a highly elastic TPU insulating layer, and nano-silica is added to the highly elastic TPU insulating layer.

[0011] In one alternative: the intermediate layer is made of aramid fiber woven mesh, which is wound at a 45° angle around the outer side of the inner layer.

[0012] In one alternative: the outer layer is made of wear-resistant polyurethane sheath, and the surface of the wear-resistant polyurethane sheath is provided with wavy textured patterns.

[0013] In one alternative: a tensile reinforcing layer is provided between the intermediate layer and the outer layer, and the tensile reinforcing layer adopts a diamond-shaped metal mesh structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model improves the torsional and tensile resistance of the cable by adopting a composite structure of spiral stranded conductor and axial reinforcing core. At the same time, by setting a three-layer composite protective sleeve, utilizing a high-elasticity TPU insulation layer, aramid fiber braided mesh and wear-resistant polyurethane sheath, the torsional and tensile resistance of the cable is further improved, and the service life of the cable is extended.

[0015] This invention further improves the tensile strength of the cable by setting a tensile reinforcing layer with a diamond-shaped metal mesh structure. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Example 1 In one embodiment, such as Figure 1 and Figure 2As shown, a composite cable for new energy power distribution equipment with torsion resistance and tensile strength includes a composite conductor 100 and a composite protective sleeve 200. The composite protective sleeve 200 is sleeved on the outside of the composite conductor 100. The composite conductor 100 includes a spirally stranded wire 101. An axial reinforcing core 102 is provided in the middle of the wire 101. The axial reinforcing core 102 is made of untwisted stranded plastic-coated steel wire. The composite protective sleeve 200 includes an inner layer 201, a middle layer 202 and an outer layer 203. The middle layer 202 is located between the inner layer 201 and the outer layer 203.

[0022] In one embodiment, such as Figure 2 As shown, the conductor 101 is made of pre-deformed soft copper wire 103 spirally twisted together. The outer side of the conductor 101 is covered with silver-plated copper-clad steel reinforcing wire 104. The spirally twisted pre-deformed soft copper wire 103 gives the conductor 101 natural torsional elasticity.

[0023] In one embodiment, the diameter of a single pre-deformed soft copper wire 103 is ≤0.2mm, and the stranding pitch ratio is 6-8 times.

[0024] In one embodiment, such as Figure 2 As shown, the stranding direction of the silver-plated copper-clad steel reinforcing wire 104 is consistent with the stranding direction of the conductor 101. The silver-plated copper-clad steel reinforcing wire 104 can both share the tensile load and prevent separation from the conductor 101 when twisted.

[0025] In one embodiment, the inner layer 201 is a high-elasticity TPU insulation layer with added nano-silica. The high-elasticity TPU insulation layer can effectively buffer and disperse pressure. By adding nano-silica, the toughness and thermal stability of the high-elasticity TPU insulation layer can be improved.

[0026] In one embodiment, the intermediate layer 202 is made of aramid fiber woven mesh, which is wound at a 45° angle around the outer side of the inner layer 201. The aramid fiber woven mesh can resist tensile and torsional loads simultaneously.

[0027] In one embodiment, the outer layer 203 is made of wear-resistant polyurethane sheath, and the surface of the wear-resistant polyurethane sheath is provided with wavy textured surface, which can reduce the surface friction coefficient when the cable is twisted.

[0028] The above embodiments disclose a composite cable for new energy power distribution equipment that is resistant to torsion and tension. It adopts a composite structure of spiral stranded conductor 101 and axial reinforcing core 102, which improves the cable's torsion and tensile performance. At the same time, by setting a three-layer composite protective sleeve 200, and utilizing a high-elasticity TPU insulation layer, aramid fiber braided mesh and wear-resistant polyurethane sheath, the cable's torsion and tensile performance is further improved, and the cable's service life is extended.

[0029] Example 2 The difference from Example 1 is that, as Figure 3 As shown, a tensile reinforcing layer 300 is provided between the intermediate layer 202 and the outer layer 203. The tensile reinforcing layer 300 adopts a diamond-shaped metal mesh structure, which further improves the tensile performance of the cable.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
