Description

Technical Field

[0001] The invention relates to cable processing, and more specifically to a moisture-keeping, wind-erosion-resistant, and aging-resistant wind power cable and a preparation method thereof. Background Art

[0002] The impact of long-term slow wind erosion is reflected in long-term dust and sand-blowing weather. The wind vibration effect and erosion of wind power cables will cause performance degradation and aging.

The left and right ends of the metal sleeve I 61 are integrally connected with the metal sleeve II 62. The diameter of the metal sleeve II 62 is smaller than the diameter of the metal sleeve I 61, so that a shoulder is formed on both sides of the inner wall of the metal sleeve I 61.

[0033] The preparation method comprises the following steps:

[0034] Step 1: Place two connecting sleeves one above and one below;

[0035] Step 2: heating the inner surface of the metal sleeve II 62 to 100 to 140 degrees Celsius;

[0036] Step 3: Take two cables with TPU outer layers, remove the outer armor at the ends of the two cables, connect the inner cores of the two cables, and place the connected inner cores of the cables between the two connecting sleeves;

The inner end faces of the two metal sleeves II 62 are respectively fitted with the outer layers of the two cables to fix the two connecting sleeves. Preferably, the connecting sleeve also includes a protrusion 63 arranged on the inner surface of the metal sleeve II 62. The protrusion 63 melts the outer layer of the cable and is fixed inside the TPU after cooling. The entire inner end face of the metal sleeve II 62 is also completely fixed to the outer layer of the cable by melting after cooling to achieve complete sealing. The connecting sleeve is used to protect the cable connection to resist wind erosion and aging. The cable with a TPU outer layer is used in combination with a hot-melt sealing method to further enhance the anti-wind erosion effect. In addition to having a flame retardant effect, the flame retardant sponge 64 also has a moisture absorption effect.

[0038] Preferably, Figure 8 As shown, the metal sleeve Ⅰ 61 is provided with a flame retardant sponge 64 for wrapping the inner core of the cable.

[0039] The steps 1 to 4 are implemented using a cable processing device, which includes:

[0040] Linear displacement mechanism and support assembly;

[0041] like Figure 2 and 3 As shown, the linear displacement mechanism includes a support frame 11, a double-headed screw Ⅰ12 and a motor 13. Specifically, two double-headed screws Ⅰ12 extending left and right are rotatably connected to the support frame 11, and the left and right sides of the double-headed screw Ⅰ12 have opposite thread rotation directions. The left parts of the two double-headed screws Ⅰ12 are synchronously driven by a pulley belt assembly, and one of the double-headed screws Ⅰ12 is driven to rotate by the motor 13, and the motor 13 is installed on the support frame 11;
