Twin-core leaky cable

The utility model belongs to the technical field of wires and cables and especially relates to a twin-core leaky cable suitable for a leaky cable perimeter intrusion detecting system. The twin-core leaky cable includes a cable, protection layers and a sheath. The cable includes two parallel wire cores. Each of the wire cores is wrapped with an insulation layer and a shielding layer respectively. The protection layers are filled between the sheath and the shielding layers. A copper net braid is arranged outside a side of a contact point of the two wire cores on the shielding layer while an open groove is arranged on the opposite side. The utility model adopts a design idea of a single cable having two cores and arranges the two leaky cables for transmitting and receiving into the sheath skillfully. Therefore, the twin-core cable can be installed in a single cable channel or a single cable groove, thereby simplifying an installation process substantially, reducing the installation time and the corresponding cost, and reducing the working amount of laying the twin-core leaky cable by half. The twin-core leaky cable becomes suitable for installing in a narrow area. The twin-core leaky cable provided by the utility model also has advantages of high concealment, high sensibility, high anti-interference capability, low missing report rate, low error report rate, low material consumption and the like.
