The invention discloses a leading cable of an electric motor, belonging to the technical field of a cable. The leading cable of the electric motor comprises a conductor, an internal insulating layer, an external insulating layer and an outer sheath. The leading cable of the electric motor is characterized in that the conductor is composed of copper wire twisting bunches; the internal insulating layer is extruded and packed on the conductor, a polyimide film corona-proof layer is wrapped and packed on the internal insulating layer; the external insulating layer is extruded and packed on the corona-proof layer; an aluminum tape layer is wrapped and packed on the external insulating layer, and the outer sheath is extruded and coated on the aluminum tape layer. The leading cable of the electric motor is reasonable and simple in structure, likely to produce and manufacture and low in cost; and the leading cable is thin in insulation, good in corona-proof performance, high in puncture voltage, big in heat resisting index, good in stability and reliability, excellent in heat conductivity, strong in insulating adhesiveness, and good in moistureproof and chemical performances; the leading cable can be applied to coal mine, oilfield, chemical industry fields and communication, navigation, electronic countermeasures, wireless device, radio and television, and similar electronic devices to transmit high frequency and ultra-high frequency signals; and the leading cable also can be applied to the field with relatively high requirements on heat resistance and interference resistance.
Description
technical field [0001] The invention relates to a structure of a cable, in particular to a structure of an anti-corona lead-connecting cable for a variable frequency motor, and belongs to the technical field of cables. Background technique [0002] Economic development needs to rely on energy. Energy saving and consumption reduction are the top priorities. Frequency conversion is an excellent energy-saving technical solution. Frequency conversion motor technology has been rapidly popularized and applied. With the rapid development of frequency conversion motor applications, the service life of frequency conversion motor lead cables has attracted people's attention. Existing cables are generally composed of conductors, insulation, and outer sheaths. The outer sheath is provided on the cores of which the outer surfaces of the conductors are extruded with an insulating layer, which cannot meet the needs of variable frequency motors. It is a common occurrence that the lead cabl...
