Embodiment Construction
[0016] In order to further illustrate the present invention, a preferred embodiment is given in detail as follows in conjunction with the accompanying drawings:
[0017] see figure 1 , which is a schematic structural diagram of a herringbone-shaped insulation tower 100 with diagonally-stayed rods for power grid transmission lines according to the first embodiment of the present invention. The herringbone-shaped insulation tower 100 with diagonally-stayed rods for the grid transmission line includes two main rods 10, 11, at least one cross-arm 12 arranged on the main rod 10 or the main rod 11, and at least one for connecting the Metal connecting piece 16 between main pole 10 or main pole 11 and cross arm 12 .
[0018] The main rods 10, 11 are prepared by impregnating glass fiber yarns in resin through a pultrusion or winding process. The glass fiber yarn can be non-alkali uninterrupted glass yarn. The resin may be polyurethane resin or vinyl ester resin or the like. When th...

The invention discloses an inverted V-shaped insulating tower with a diagonal member for a power grid transmission line. The insulating tower comprises at least two main rods, at least one cross arm and at least one diagonal member, wherein the cross arm is arranged on the main rod; the diagonal member is arranged between the main rod and the cross arm; the two main rods are connected in an inverted V shape; the cross arm comprises an insulating rod and an umbrella body which is arranged outside the insulating rod; the umbrella body is made of vulcanized silicone rubber; one end of the insulating rod is connected with the main rod, and the other end of the insulating rod is connected with a suspension hardware; the suspension hardware axially extends along the cross arm and is used for arranging the transmission line; in the composite insulating tower for the power grid transmission line, the main rods and the cross arm which are made of a composite material are used as supporting members for the transmission line; and a sheath and an umbrella skirt are arranged outside the cross arm, so that an insulator string is saved in the composite insulating tower for the power grid transmission line; and thus, the length of the cross arm can be reduced, the cost and the weight of pole and tower are reduced and the occupied area of the power rod and tower is further reduced.
Description
technical field [0001] The invention relates to a power pole tower used in a power transmission line, in particular to a composite insulation tower for a power grid transmission line. Background technique [0002] The tower structure is an important special supporting structure in infrastructure such as power transmission, communication, railway, municipal and so on. The structure and material of the tower will directly affect the safety, economy and reliability of the line. The poles and towers widely used in overhead transmission lines at home and abroad mainly include wooden poles, concrete poles or prestressed concrete poles, steel pipe concrete poles, steel pipe poles and iron towers. Among them, the iron tower is a pole tower form commonly used in ultra-high voltage transmission lines in various countries in the world. Generally, concrete poles are used in 35KV ~ 110KV lines. At present, concrete poles are also used in plains and hilly areas with better transportation...
