Embodiment Construction

[0015] In order to further illustrate the present invention, a preferred embodiment is given in detail as follows in conjunction with the accompanying drawings:

[0016] see figure 1 and figure 2 , which is a schematic structural diagram of a power grid transmission line tower 100 provided by the present invention. The grid transmission line tower 100 includes a main pole 10 and at least one cross arm 11 arranged on the main pole 10 .

[0017] It should be further explained that the above-mentioned power grid transmission line tower 100 is an umbrella-shaped tower. It is conceivable that the power grid transmission line tower 100 can also be a bird-bone transposition tower, a bridge transposition tower, a cat-head-shaped tower, a cup-sprinkling tower, a dry-shaped tower, a horn-shaped tower, and a door-shaped tower. One of the towers and more. These types of pole tower structures are the same as the upper-shaped towers in that they all include basic components such as mai...

Abstract

The invention relates to a pole tower for a power transmission line of a power grid, comprising a main pole and at least one cross arm, wherein the cross arms are arranged on the main pole; the main pole is made of metal materials; each cross arm comprises a hollow insulating pole and a shed, wherein the shed is arranged at the outer side of the insulating pole and made of vulcanizing silicone rubber; one end of the hollow insulating pole is connected with the main pole, and the other end is connected with a suspended hardware tool; the suspended hardware tool extends along the axial direction of the cross arm and is used for arranging the power transmission line; and the hollow insulating pole is manufactured by soaking glass fiber yarns in resin materials. By using the cross arm made from composite materials as a supporting member of the power transmission line, the pole tower for the power transmission line of the power grid can directly suspend the power transmission line on the cross arm because an insulating umbrella body is arranged outside the cross arm so that the usage of an insulating substring is eliminated, thereby the total height of the pole tower is reduced and then the cost and the weight of the pole tower are decreased.

Description

technical field [0001] The invention relates to a power tower used in a power transmission line, in particular to a power tower used in 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 and constructio...
