Abstract

The invention relates to a variable-frequency cable, which comprises an outer sheath layer 8 and an insulating layer 5, wherein the outer sheath layer 8 comprises fluororubber, polyisocyanate and a polyurethane elastomer; the insulating layer 5 comprises an inner insulating layer and an outer insulating layer; the inner insulating layer comprises fluoroplastic and polyvinyl chloride; and the outer insulating layer comprises nylon 66. The invention further relates to an application of the variable-frequency cable in irrigation facilities. The cable provided by the invention has the advantages of stable structure, good waterproof property, ageing resistance, good mechanical property and good support effect, and is suitable for relatively high environment temperature and a humid environment with poor heat dissipation.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a frequency conversion cable. Background technique [0002] The frequency conversion cable is mainly used for the connection between the frequency conversion power supply and the frequency conversion motor. Frequency conversion cables have a series of advantages, such as low transmission impedance, good electromagnetic compatibility, low working capacitance, good anti-interference and low radiation performance, etc. In the field of irrigation motors, multi-core cables with fillers are mostly used. The disadvantages are low mechanical strength, easy deformation, low reliability, poor hygroscopicity, and poor corrosion resistance, especially in humid, water-immersed and corrosive environments. , the structural stability of the cable cannot be maintained, which seriously affects the reliability and life of the motor. Therefore, we try to use variable frequency cables with outstandi...
