The invention discloses a T-type cable clamp with a single conductor and double downleads. The T-type cable clamp comprises a cross bar, wiring terminals are vertically connected to both ends of the cross bar separately, an equipment cable clamp is connected below the wiring terminals, the wiring terminals are detachably connected with the equipment cable clamp, and the equipment cable clamp is provided with a cable hole. The invention provides a novel compressed T-type cable clamp with single conductor and double downleads for solving the construction inconvenience resulting from that the wiring terminals of the T-type cable clamp are connected with the equipment cable clamp with double downleads when double-branch leads are lapped with the same point of a bus; according to the T-type cable clamp disclosed by the invention, two wiring terminals are welded below a drawer type aluminum tube, and a certain distance is reserved between the two wiring terminals, thereby being facilitate for the installation of the equipment cable clamp; and the T-type cable clamp disclosed by the invention is simple and reliable in structure, low in cost and wide in application range, the two wiring terminals of the novel T-type cable clamp are separately connected with the equipment cable clamp of the downleads, thereby both meeting the construction safety requirements and facilitating the connection of the downleads.
