變頻電纜的性能及用途講解
變頻電纜的結(jié)構(gòu)包括三根主線絕緣線、三根零線絕緣線，在主線絕緣線和零線絕緣線外依次設(shè)置內(nèi)繞包層、銅帶層、外繞包層和外護(hù)套層，形成3+3線芯結(jié)構(gòu)，使電纜具有較強(qiáng)的耐電壓沖擊性，能經(jīng)受高速頻繁變頻時的脈沖電壓，對變頻電器起到良好的保護(hù)作用。
應(yīng)用場合：
該產(chǎn)品主要用于變頻器與變頻電機(jī)之間連接用供電電纜，采用3大3小的對稱式結(jié)構(gòu)設(shè)計及雙層復(fù)合屏蔽結(jié)構(gòu)，有更好的電磁相容性，對抑制電磁干擾起到一定的作用，能抵消高次諧彼中的奇次頻率，提高變頻電機(jī)電纜的抗干擾性，減少了整個系統(tǒng)中的電磁輻射。
application
this product is mainly used for the power supply cable for connection between the inverter and the inverter motor. it adopts 3 large and 3 small symmetrical structure design and double-layer composite shielding structure. it has better electromagnetic compatibility and plays a certain role in suppressing electromagnetic interference. the function can offset the odd-order frequencies in high-order harmonics, improve the anti-interference performance of the special-purpose cable for variable frequency motors, and reduce the electromagnetic radiation in the entire system.
