Product Overview
Non-electronic type, long life.
The quality of protection will not change after lightning strikes.
Model with different protection radius for selection.
Fully active triggered lightning system.
When there is lightning, self-activation will be acted.
Elegant appearance.
No need maintenance.
LY30Z series of pre-discharge lightning rod uses high-quality steel materials; each model has different characteristics corresponding to different protection range.
Product Structure
1.Central collection rod
2.Reflector
3.Trigger device
4.Actuator
5.Fixed plate for actuator
There is a round hole on the reflector corresponding to each actuator, and the reflector is electrically connected to the central collection rod and the ground, and the base of actuator is made of synthetic resin and it is suitable for any corrosive environment.

Note: The above data is the test result when the height of the lightning rod H = 5 meters.
Calculation method of the protection radius of the active pre-discharge lightning rod
Suppose that the forestall start time of the lightning rod is T, then the forestall distance of upward leader △ L=V=V* △ T according to the calculation method provided by NFC-17-102 standard, the protection radius Rp is calculated according to the following formula: Representative= h(2D-h)+ △ L(2d+ △ L)h≥5
D motor distance, it depends on the level of protected buildings, for level lll protection object,D values are 20m, 45m,60m separately. h is the distance from the top of the lightning rod to the protected plane.
△ T is tested by the evaluation and calculated (see table above) V=106m/s, △ L=V* △ T
