Anti-harmonic shielding cable for VFD of electric vehicle

The utility model provides an anti-harmonic shielding cable for a VFD of an electric vehicle, which belongs to the technical field of cables, adopts twisted-pair wire cores, is designed according to a certain pitch, and is targeted to resist complex harmonic interference. An electric field homogenization layer structure is introduced, so that the electric coupling resistance of the cable to multiple harmonics is enhanced; the cable has a composite anti-harmonic structure and comprises an aluminum foil layer, a braid layer, an electric field homogenization layer and a twisted pair wire core from outside to inside. Complex harmonic waves around the VDF can be filtered layer by layer, and the integrity of transmission signals of the wire core can be ensured. 本实用新型提供了一种电动车VFD用抗谐波屏蔽电缆，属于电缆技术领域，采用对绞线芯，按照一定节距设计，有针对性抗复杂谐波干扰；引入电场均化层结构，增强电缆对多次谐波的抗电耦合性能；电缆具有复合抗谐波结构，从外至内：铝箔层、编织层、电场均化层和对绞线芯。对VDF周围的复杂谐波，具有逐层过滤作用，能够保证线芯传输信号的完整性。
