description The utility model relates to a power-line carrier isolator, which comprises an installing casing, a high-frequency trap network which is composed of two K type 'U'-shaped lowpass filter circuits, and a high frequency choke network which is connected with the output end of the high frequency trap network, wherein, the output end of the high frequency choke network is connected with a power network of a user. The utility model has the advantages that the higher-order harmonics caused by circuit used by other users in a commercial power network and the wave interference caused by a supply line can be attenuated; the power frequency signal of a power line carrier device of the user can be prevented from being transmitted to the outside line; the attenuation of the power line carrier information of the user is small; the technology of the power line carrier can be promoted to be widely used.
