Described metal steel tower tower body also is provided with the lower support with upper support frame consistent size with insulation tower body junction
Frame, is provided with under two diagonally intersected auxiliary cross bar, along line direction at two in described lower bracing frame
It is provided with a down conductor between cross point and the lower bracing frame of lower auxiliary cross bar and enters floor-engaging frame, described ground connection
Downlead enters to have the lower installing hole corresponding with upper installing hole in floor-engaging frame.
Preferably, described upper installing hole is opened in the center of down conductor support；It is equal from each back gauge,
Be conducive to keeping stable electric property.
Preferably, one end of described down conductor support is connected by connecting plate and two upper auxiliary cross bar,
Described connecting plate is rectangle, and the anterior angle of described connecting plate is connected with two upper auxiliary cross-car points, described company
The left comer of fishplate bar is connected with a upper auxiliary cross bar, and described right corner is connected with assisting cross bar on another root, described
Relief angle is connected with one end of down conductor support, and the other end of described down conductor support is solid by bolt
It is scheduled on upper support frame；Make down conductor support more be firmly fixed, two auxiliary can be kept simultaneously
The relative position of cross bar.
Compared with prior art, the invention have the advantage that this device solves tower grounding downlead by its tower
The problem that " cross " crossing rod piece at body center blocks, down conductor avoids and connects with tower body insulant
Touch, played the insulating effect of composite tower body so that wire creep age distance over the ground strengthens, and enhances
The ability of its pollution flashover of resistance to power frequency, it is to avoid down conductor is placed on outside shaft tower tower body, it is simple to safeguard, and
Easily operated execution.
Accompanying drawing explanation
Fig. 1 is the axonometric chart of the present invention a kind of 110kV lattice composite material pole tower；
Fig. 2 is the structural representation of upper support frame in the present invention a kind of 110kV lattice composite material pole tower.
Detailed description of the invention
Refering to the embodiment that Fig. 1, Fig. 2 are the present invention a kind of 110kV lattice composite material pole tower, a kind of
110kV lattice composite material pole tower, including the metal steel tower tower body 1 fixed on the ground be fixed on gold
Belonging to the compound material insulation tower body 2 on steel tower tower body 1, described insulation tower body 2 top is provided with metal angle cross-arm
3, the middle part of described metal angle cross-arm 3 is provided with the upper support frame 4 of rectangle, along right in described upper support frame 4
Linea angulata is provided with the upper auxiliary cross bar 5 of intersection, along line direction assist on two the cross point of cross bar 5 with on
Being provided with a down conductor support 6 between support 4, the center of described down conductor support 6 has arrangement
The upper installing hole 7 of down conductor 12；
Described metal steel tower tower body 1 also is provided with and upper support frame 4 consistent size with insulation tower body 2 junction
Lower bracing frame 8, is provided with under two diagonally intersected auxiliary cross bar 9, along circuit in described lower bracing frame 8
