Embodiment Construction
[0008] The present invention will be further described below in conjunction with accompanying drawing;
[0009] Such as figure 1 As shown, a waterproof wear-resistant frequency conversion tensile power cable is composed of a power core one, a power core two, a copper-clad steel armor layer 4, an alloy lead sheath shield layer 5 and a silicone rubber outer sheath 6, The first power line core is formed by extruding polyethylene insulating layer 2 with five copper core conductors 1; the second power line core is made of polyethylene insulating layer 2 extruding four copper cores with a cross-sectional area of 35 square millimeters Conductor 1 and a copper core conductor 1 with a cross-sectional area of 10 square millimeters; the three power cores 1 are tightly pressed, and the three power cores 2 are arranged at the outer gap of the first contact portion of every two power cores. Three power cores one and three power cores two are extruded into cable cores by water-blocking...

The invention discloses a waterproof wear-resistant variable frequency tensile power cable, which is formed by three power cable cores I, three power cable cores II, a copper clad steel armor layer, an alloy lead sheath shielding layer and a silicon rubber outer sheath; the three power cable cores I are tightly compacted; the three power cable cores II are arranged in the gaps outside the contacting parts of every two power cable cores I; the three power cable cores I and the three power cable cores II are extruded to form a cable core by a water stop tape wrapping layer; the silicon rubber outer sheath, the alloy lead sheath shielding layer and the copper clad steel armor layer are extruded on the cable core from outside to inside; a ground wire core is coaxially arranged in the cable core. A ground wire core is arranged in the copper clad steel armor layer. The waterproof wear-resistant variable frequency tensile power cable is stable in performance, has excellent waterproof property, antijamming property and tensile property and is stable in current and good in wear resistance.
Description
technical field [0001] The invention relates to cables, in particular to a waterproof, wear-resistant, variable-frequency, tensile-resistant power cable. Background technique [0002] A notable feature of the construction of railways, tunnels, mines, and bridges is the harsh environment. The cables used for construction in such places are often soaked in water, and dragged around during use, causing great signal interference and severe wear. At present, the structure of the cables commonly used in such occasions is poor in waterproof performance, bending performance, and wear resistance. During the construction process, the sheath is easily damaged due to the dragging of the cable, the service life is short, and the signal is severely interfered. , the current is unstable. Contents of the invention [0003] According to the above situation, the object of the present invention is to provide a waterproof, wear-resistant, variable frequency and tension-resistant power cable...
