[0012] (Three) beneficial effects

[0013] Compared with the prior art, the novel low-voltage tensile cable has the following beneficial effects:

[0014] 1. The novel low-voltage tensile cable, the support center frame at the center serves as the basic framework of the entire cable structure, plays a crucial supporting and positioning role, and has six center axis symmetric conductors precisely inserted therein. The symmetrical distribution ensures that the conductors are uniformly stressed inside the cable, reduces the risk of internal structure deformation or damage caused by uneven stress, and guarantees the stability of power transmission. Meanwhile, the six center axis symmetric and annular wire connecting rings fixed outside the support center frame provide a key transition for the connection of subsequent layers of structure. The insulating connecting holes of the layer annular rings opened in each wire connecting ring enable the insulating layer to be closely inserted and installed, thereby effectively isolating the conductors from other components and eliminating the risk of electric leakage, ensuring the safety and reliability of power transmission. The insulating layer is annularly distributed outside the conductors, and through its good insulating performance, prevents current leakage and short circuit between different phase conductors, ensuring that power can be stably transmitted along the predetermined path in the conductors, laying a foundation for the normal operation of the entire power system.

[0015] 2. The novel low-voltage tensile cable, the shielding layer sleeved outside the support center frame is closely inserted with the support center frame through the circular through holes in the shielding layer, and is fixedly connected by using an adhesive, forming a continuous and stable shielding system. This shielding layer can efficiently block external electromagnetic interference, prevent the complex external electromagnetic environment from adversely affecting the electrical signals transmitted inside the cable, maintain the integrity and accuracy of the signals, and also prevent the electrical signals inside the cable from leaking outward, avoiding interference with surrounding other electronic equipment and improving the electromagnetic compatibility of the entire power system. In addition, the semispherical anti-extrusion protrusions in annular array and equal distribution on the outer cylindrical surface of the shielding layer can uniformly disperse the pressure when the cable is subjected to external extrusion, reducing the damage to the shielding layer and the internal structure caused by local pressure concentration, effectively enhancing the extrusion resistance of the cable, enabling it to maintain normal working state in relatively harsh installation and use environment. The filler fills the gap between the shielding layer and the tensile layer, not only plays a buffering and supporting role to avoid mutual friction or collision of the internal structure due to external impact, but also prevents impurities such as water and dust from entering the inside of the cable, protecting the performance and service life of the internal electrical components and ensuring the stability of the cable during long-term use.

[0016] 3、The new low-voltage tensile-resistant cable, the tensile-resistant layer as the core guarantee of the tensile-resistant performance of the cable is made of high-strength material, has excellent tensile strength and toughness, when the cable is subjected to axial tension, the tensile-resistant layer can bear most of the tension by virtue of its strong mechanical properties, effectively prevents the cable from being broken due to stretching, ensures the continuity of power transmission, which enables the cable to adapt to various complex laying scenes, such as vertical laying in the vertical shaft of a building, long-distance overhead laying in an industrial plant, etc., meets diversified engineering needs, the outer protective sleeve and the wear-resistant layer provide comprehensive physical protection for the cable, the outer protective sleeve can resist mechanical damage, chemical corrosion and ultraviolet radiation and other adverse factors in the daily environment, prevent the internal structure from being damaged, and the wear-resistant layer further enhances the wear resistance of the cable, so that it can still maintain the integrity of the surface in the case of frequent contact or friction with other objects, reduces the performance decline caused by wear, thereby greatly prolongs the service life of the cable, reduces the maintenance cost, and ensures the long-term stable operation of the power system.
