Abstract
The invention belongs to the technical field of cable materials and cables, in particular to a cross frame. The cross frame is characterized by being composed of four frame pieces connected together at one end and a reinforcing member, the four frame pieces form a cross, the reinforcing member is arranged in the center of the cross, the axes at any cross section of the adjacent frame pieces are at 90 degrees, the edges of the other ends of all of the frame pieces are arranged on the same circumference, and the cross frame is integrally formed. The invention also discloses a cable with the cross frame. According to the cross frame, a frame groove is arranged between the adjacent frame pieces, transmission lines are arranged in the frame groove to be taken out easily as needed without unwinding all transmission lines, so that the construction is very easy, construction workers only need to uncover the portion outside and corresponding to the transmission lines at position, of a protective layer rather than cutting the whole protective layer, and the cable is effectively protected. The cross frame has the main advantages of being easy to construct and manufacture and effective in cable protection.
