Therefore, it is crucial to develop power cables with excellent pressure resistance. Traditional power cables have limitations in terms of pressure resistance. The new pressure-resistant power cables significantly improve their pressure resistance and service life by using high-strength materials and advanced processes, meeting the stringent requirements of modern power transmission.

[0003] The utility model with the announcement number of Chinese CN219676949U discloses a breathable pressure-resistant power cable, including a power core, a plurality of pressure-resistant frames are arranged outside the power core, each pressure-resistant frame is arranged as an arc-shaped strip structure, and is arranged in a corresponding annular direction and wrapped around the outside of the power core to cover the entire power core; and the size of each pressure-resistant frame is set accordingly, so that a breathable gap is formed between adjacent pressure-resistant frames. The traditional cables of this device are all layered structures in order to increase pressure resistance, and heat is difficult to transfer out.

[0004] In the process of implementing this application, it was found that the technology has the following problems: in the above patent documents, the power cord only uses the limited activity of the slot and the plug rod to resist pressure, and the pressure resistance effect is limited. It is difficult to ensure that it can still maintain a stable working state when facing adverse factors such as wind, rain, and vibration.

[0005] For this purpose, a pressure-resistant power cord is proposed. Utility Model Content

[0010] Furthermore, a plurality of groups of filling ropes are arranged inside each group of the cross interlayers, and the plurality of groups of filling ropes are arranged in parallel in the corresponding cross interlayers, and the filling ropes are made of polypropylene material.

[0011] Furthermore, the four groups of cross-layers separate the eight groups of side buffer layers into four pairs, and an inner sheath is arranged between each pair of side buffer layers.

[0013] Furthermore, each group of the inner sheaths is provided with a main body filler between the corresponding side buffer layers, and the main body filler is made of PE material.

[0014] Furthermore, the cross interlayer, the curved pressure bearing member, the inner sheath and the inner shielding layer are all distributed along the length direction of the wire core.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] 1. In the utility model, a pressure-resistant power cord is provided with an outer sheath made of TPU material on its periphery, which has super wear resistance, so that the power cord can still maintain good performance during long-term use, and an outer tensile baffle is provided inside the outer sheath to ensure that the power cord can still work normally under external violent impact or pressure conditions. Four groups of cross interlayers are symmetrically arranged inside the external tensile body, and several groups of filling ropes are arranged inside the cross interlayers. The filling ropes are made of polypropylene material to improve the mechanical buffering effect of the cable and improve the appearance quality.

[0017] 2. In the utility model, an inner sheath is arranged between each pair of side buffer layers to strengthen the pressure protection of the wire core. When facing adverse factors such as wind, rain, vibration, etc., the bent pressure-bearing parts are deformed to reduce the loss of pressure on the internal wire core. At the same time, a main body filler is added between the side buffer layer and the inner sheath, which helps the cable to maintain its structural integrity and stability when subjected to external pressure. An internal shielding layer is arranged on the periphery of the corresponding wire core to form an insulating structure to prevent current and voltage leakage and ensure the power-on safety of the power cord.
