The invention relates to the field of power facilities, and particularly to a connectable puncture wire clamp. The connectable puncture wire clamp comprises an upper clamping board and a lower clamping board. The upper clamping board is connected with the lower clamping board through a clamping device. When the upper clamping board and the lower clamping board are folded, two wire clamping ducts are formed. One wire clamping duct in the two wire clamping ducts is internally provided with a connecting ring. Two sides of the lower clamping board are provided with spacing rings which surround theconnecting ring. Two sides of the lower clamping board are provided with spacing boards. The clamping device comprises fastening bolts and torque nuts. The upper clamping board and the lower clampingboard are respectively provided with at least three stabbing plates internally. The stabbing plates in the upper clamping board are in one-to-one correspondence with the stabbing plates in the lowerclamping board. Two ends of the stabbing plate are provided with stabbing teeth. Two sides of the stabbing teeth of at least one stabbing plate in the two stabbing plates which are correspondingly arranged are provided with puncture grease-applying devices. The connectable puncture wire clamp can realize effective electric connection on the condition that a position distance between a branch lineand a main line are overlarge, and has advantages of simple operation and high safety.
