Title:
CROSS ARM AND ANGLE TOWER AND TENSION SUPPORT COMPRISING THE SAME
Document Type and Number:
WIPO Patent Application WO/2018/019180
Kind Code:
A1
Abstract:
Provided is a cross arm(110), one end of which is connected to a tower body (101), and the end of the cross arm (110) away from the tower body (101) is a free end for connecting a conducting wire (103). The free end comprises an end connecting piece (111) and an extension piece (112). The extension piece (112) is fixed with the end connecting piece (111). In a horizontal projection, the extension piece (112) protrudes from the end connecting piece (111) and the conducting wire (103) is connected to the extension piece (112). The angle between the extension piece (112) and a center line of the cross arm (110) is greater than the angle between the conducting wire (103) and the center line of the cross arm (110). The free end of the cross arm (110) is further provided with a jumper wire device (120), which is horizontally arranged on the end connecting piece (111) and is used for hitching the jumper wire. By using the extension piece, the distance between the conducting wire and the tower body can be increased under the condition that the turning angle is met, thereby the requirement for a electrical gap between the conducting wire and the tower body is met, and there is no need to increase the length of the cross arm. By horizontally arranging the jumper wire device on the end connecting piece, the jumper wire device does not occupy the space in the vertical direction, thereby the distance between wire layers can be reduced, and therefore the size of the tower body can be reduced.
