变频电缆的性能及用途讲解

变频电缆的结构包括三根主线绝缘线、三根零线绝缘线,在主线绝缘线和零线绝缘线外依次设置内绕包层、铜带层、外绕包层和外护套层,形成3+3线芯结构,使电缆具有较强的耐电压冲击性,能经受高速频繁变频时的脉冲电压,对变频电器起到良好的保护作用。

应用场合:
 

该产品主要用于变频器与变频电机之间连接用供电电缆,采用3大3小的对称式结构设计及双层复合屏蔽结构,有更好的电磁相容性,对抑制电磁干扰起到一定的作用,能抵消高次谐彼中的奇次频率,提高变频电机电缆的抗干扰性,减少了整个系统中的电磁辐射。

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.
