Problems solved by technology
The disadvantage is that the frequency conversion cable is often subjected to radial external force during use. Since there is no radial mechanical protection layer, the cable is easily damaged in the radial direction during use. In addition, the electromagnetic interference between the phase cores can be further improved.

Embodiment Construction
[0007] Frequency conversion cable, the three main cores are composed of conductor 1, insulating layer 2, sub-shielding layer 3, and sheath tube 4 from inside to outside. After the three cores are cabled, the inner sheath 5 is wrapped, and the inner sheath 5 is filled with the three cores. Filling material 10 is provided, and shielding layer 6, isolation sleeve 7, galvanized steel tape armor layer 8 and outer sheath 9 are placed outside the inner sheath 5 in sequence.

The invention is a variable frequency cable, relating to the field of wire and cable technique, comprising three main wire cores, where the three cores are made into a cable and then lapped with inner jacket, there are fillings between the inner jacket and the three cores, the inner jacket is externally equipped with screening layer and outer jacket, an armouring layer is arranged between the screening layer and the outer jacket, the armouring layer is separated from the screening layer by isolating sleeve, and the armouring layer radially protects the cable and simultaneously plays a role of complementing electromagnetic wave screening.
Description
technical field [0001] The invention relates to the technical field of wires and cables, in particular to a frequency conversion cable. Background technique [0002] General 1.8 / 3KV and below frequency conversion motor special frequency conversion cable, each insulated wire core is cabled and used as a total shield, the structure can use copper wire and copper tape combination shield, copper wire braided shield, copper tape shield, copper wire braided copper tape shield, etc. , such as Chinese patents 03221286.0, 200520075394.3, and 200520075395.8, the shielded cable can resist electromagnetic induction, poor grounding and power line conduction interference, reduce inductance, and prevent excessive induced electromotive force. The shielding layer can not only suppress the emission of electromagnetic waves, but also serve as a channel for short-circuit current, and can protect the neutral core. The disadvantage is that the frequency conversion cable is often subjected to rad...
