Cable testing bridge

The utility model discloses a cable testing bridge, which consists of a bridge cover plate and a trough type bridge. The trough type bridge consists of a side plate and a base plate; the side plate is provided with radiating holes; and the base plate is provided with at least two U-shaped grooves along the axial direction of the bridge. With the technical proposal, as the U-shaped grooves on the base plate of the bridge are axially arranged along the bridge, the stamping and the processing of the engineering become simple and the cable testing bridge can be formed by one-step stamping. Three U-shaped grooves arranged on the base plate can be provided for a three-phase alternating current circuit to use, and can increase the rigid strength of the base plate. While the rigid strength of the bridge cover plate and the trough type bridge are maintained, the radiating holes on the side plate can play a good role in radiation.
