ESE Lightning Rod Early HD-TESE2500 Advance Discharge Lightning Rod Lightning Protection System
Lightning rod protection range
Lightning rod protection range should be calculated in accordance with GB50057-2010 "Building Lightning Protection Design Code" Appendix IV "rolling ball method to determine the protection range of the flash catcher" method provisions. If the design requirements are not met, you can increase the lightning rod by adding a connecting rod to raise the lightning rod.
Single-pin lightning arrester, a non-inductive, low-impedance metal inner conductor lead wire, the lightning current to earth, and make the protected antenna pole or building does not occur side strike and charged. In most cases the impact of the electrostatic field cable is less than 1/10 of the impedance of the tower, avoiding the building or tower charged, flashover; limit the intensity of the incident lightning current, so that the protected equipment to reduce the harm of backlash and induced overvoltage.
Lightning rod installation
After the lightning rod components are assembled, fastened with bolts or welding methods, the lightning rod as a whole fixed in the base.
1, the installation of lightning rod should be connected reliably.
2, after installation is complete, lightning rod each connection or metal surface coating damage, should do rust-proof treatment.
Fourth, the lightning rod maintenance
Lightning rod into use, the annual thunderstorm season before the following content to check.
(1) lightning rod connection parts of the connection should be reliable, do not allow loose.
(2) check the lightning rod receiver to the base of the total resistance value ≤ 5Ω.
(3) lightning rod should be grounded through the lead wire (dedicated or borrowed), grounding resistance value ≤ 10Ω.
