Copper lightning rod arrester Copper Air Rod Lightning Rod for Lightning Protection sysyem

1.Introdution

Lightning Rod is composed of the following sections:

a. Main receiving lightning point:It is made up of copper alloy. It connects from downlead terminal to receiving lightning point forming a uninterrupted path to convey the lightning current to the ground.It is fixed in a lightning rod(tower)pole more than 2 meters high.

b. Discharge strike spark board;generate spark.

c. Active discharge point:collect the electric energy.

d. Waterproof stainless steel box:store the electrostatic field energy.

e. Side point of receiving lightning: it is made up of stainless steel. It can convery surrounding lightning current to the ground directly.

f. Stainless steel sleeve.

g. Install fasteners.

h. Down lead connection point.

2. Working Principle

When thunderstorm comes, thundercloud and charge accumulates.It will generate great field strength(sometimes will reach KV/M and generate enormous energy) between thundercloud and the ground. DK8-BX10 ESE lightning rod can generate guide enterclose in advance to improve the virtual height of lightning rod making the lightning strike the lightning rod exactly in the range of lightning proteciton, which avoids the phenomenon of“side striking”and” shielding failure”.

DK8-BX10 ESE lightning rod has three active discharge points. When the electric field reaches to 20KV/m, the active discharge points and main receiving lightning form strong voltage difference, then ionize near air quickly,form corona phenomenon, produce large number of charged particles,move up quickly under the action of lightning field. The insulation distance between the thunderclouds and the lightning rod will become shorter,so compared with other objects in lightning protection zones, the lightning rod will release upward leading charge in advance. The leading charge combines with downward leading th charge making dozens of(kA)lightning current to hundreds of(kA)lightning current becomes few(KA)when reaching the ground, avoiding the quadratic effect of traditional lightning rod after receiving the lightning strike and weakening the counterattack and induced overvoltage when the large current flows into the ground.Lightning rod becomes the best trigger point of thunder and lightning.

3. Character

a. Accurate thunderbolt point.

b. Maintenance-free, do not need connect additional power.

c. Activate itself only when the thunderbolt forming, completely early discharge initially.

4. Radius of protection for difference structions of differece height

5.Installation Guide

Installing DK8-BX10 ESE lightning rod shell comply with national standard of P.R China(GB50057-94)-Code for design protection of structures against lightning.

The actual construction shall comply with National Standard of P.R China(GB 50169-92)Code for construction and acceptance of grounding connection electric equipment installation engineering. Do not install or test the lightning rod in a thunderstorm weather!

a. Please notify us the technical parameters of your lightning rod mast when ordering, so that the factory can select the right interconnection splice for you to install components successfully.

b. The thickness of lightning rod’s sleeve shall not less than 4mm, which can be used as a down-conductor. There shall be two points symmetric connecting the earth electrode.

c. When the structure’s lightning protection system has more than 1 down-conductor, breaking of contact with insulation protection for each down-conductor is recommended. And the breaking of contact shall be set at 1.5~1.8m high from ground of the conductor.

d. The joint between lightning rod and down-conductor shall be welded.

e. The construction order for the earth-termination system of lightning rod shall be from top to bottom. The common earthing system shall be installed first, and then come to the down-conductor, and the lightning rod is the last step.

6. Maintenance

Regular inspection (Every half year or once a year) the following issues is required.

If the screw bolts and welds of joints are well fixed?

If the earthing conductor is connected effectively with the earth-termination system?

If the screw bolts and welds are badly rusty, please change the screw bolts and re-weld the joints?
