摘要
对于高速HSC(High Speed CAN)电线,普通汽车可以依据标准ISO 11898-2,选用非屏蔽双绞线。电动车的电磁干扰强,要求采用特制的屏蔽双绞线。测试和研究表明,带屏蔽层的CAN线的特性阻抗比去除屏蔽层的双绞线的特性阻抗要小。
UTP ( Unshielded Twisted Pair cables) can be used in ordinary auto according to high speed CAN (HSC) standard ISO 11898 -2. It is required to use ST (Shielded Twisted Pair) in electric cars due to their high electromagnetic interference. Investigation and test results show that the characteristic impedance of shielded CAN cables is lower than that of UTP.
