Description

Four times overhead wire divides pole

Technical field

The utility model relates to ultra-high-tension power transmission line technical field, and particularly a kind of four times overhead wires divide pole.

Background technology

Existing four times overhead wire branch steel pipe poles, as shown in Figure 1, general adopt six layers of cross-arm to carry out T to connect, and generally every layer of cross-arm spacing 3 meters, therefore causes shaft height to increase, and not only cost is high but also construction is very difficult.

Utility model content

The technical problems to be solved in the utility model is: in order to overcome the deficiency of existing four times overhead wire branch steel pipe poles, and the utility model provides a kind of four times overhead wires to divide pole.

The utility model solves the technical scheme that its technical problem adopts: a kind of four times overhead wires divide pole, comprise the body of rod, ground wire cross-arm group and three layer conductor cross-arm groups setting up and down, ground wire cross-arm group is all vertical with the body of rod with wire cross-arm group, every layer conductor cross-arm group comprises A cross-arm, B cross-arm, C cross-arm and D cross-arm, A cross-arm, B cross-arm, C cross-arm is one-sided cross-arm with D cross-arm and vertically between two arranges, three layers of A cross-arm in three layer conductor cross-arms are parallel to each other, three layers of B cross-arm in three layer conductor cross-arms are parallel to each other, three layers of C cross-arm in three layer conductor cross-arms are parallel to each other, three layers of D cross-arm in three layer conductor cross-arms are parallel to each other.

Described ground wire cross-arm group comprises the ground wire cross-arm of four one-sided settings, and four ground wire cross-arms are vertically arranged between two, and A cross-arm, B cross-arm, C cross-arm and the D cross-arm one_to_one corresponding in four ground wire cross-arms and every layer conductor cross-arm group be arranged in parallel.

Spacing between adjacent two layers wire cross-arm group is 3 meters.

The length of A cross-arm, B cross-arm, C cross-arm and D cross-arm is 3.2 meters.

The beneficial effects of the utility model are, four times overhead wires of the present utility model divide pole, only need three layers of cross-arm can complete propping up of four loops and connect, not only cheap, and easy construction, reliable.
