Ground polar angle ray four, earthing pole central ray, ground connection wire clip, iron powder and loess, the lightning conducter are arranged on the top of steel tower,
Earthing pole is laid in the ground connection duct around steel tower, ground connection extremely rectangular frame structure, earthing pole lead one, earthing pole lead
2nd, one end of earthing pole lead three and earthing pole lead four is connected on four angles of steel tower, and the other end is connected to ground connection
On extremely, ground connection polar angle ray one, ground connection polar angle ray two, ground connection polar angle ray three and ground connection polar angle ray four are arranged on earthing pole
On four angles, earthing pole central ray is several, is connected to by being grounded wire clip on earthing pole, iron powder is uniformly sprinkling upon ground connection
Around pole, loess uniform fold is in earthing pole and iron powder surface.
The iron powder is Iron Works Plant's general election iron powder.
So-called loess is common yellow clay.
Good effect of the present utility model：By increasing ground connection extreme ray, the contact area of earthing pole and the earth is increased, is changed
The method of better earth pole surrounding soil reaches the purpose of reduction resistivity, simple in construction in such structures and methods implementation process,
Method is easy, economic and practical, can be effectively reduced grounding resistance, plays effective lightning protection effect, protects electrical equipment to exempt from
Damage to crops caused by thunder.
