Pioneer LY-ESE3.0 Early Streamer Emission Air Terminal

Pioneer LY-ESE3.0 Early Streamer Emission Air Terminal

Product Attributes :

1. Pioneer LY-ESE3.0 is the second-generation early streamer emission air terminal developed by Guangzhou Leisidun Electrical Technology Development Co., Ltd. after five-year research and tests. It has passed domestic authoritative test and obtained multiple international certification certificates.

2. It adopts active trigger system combining pulse transformer and oscillator, converts electrostatic and electromagnetic field energy into high-voltage signal to generate massive ions, produces upward leader in advance to meet downward leader from thundercloud, so as to expand lightning protection range.

3. Features high lightning-striking accuracy, maintenance-free, no external power supply required, strong wind resistance, can cooperate with lightning online monitoring system to realize intelligent IoT lightning protection.

Product Description

Working Principle

1. Based on traditional lightning air terminal, it is equipped with active trigger system which can generate repeated high-voltage pulse signals. It generates continuous discharge path during lightning process to connect with downward leader from thundercloud and guide lightning current into ground.

2. With combination of pulse transformer and oscillator, it converts energy from electrostatic field and electromagnetic field into high-voltage signal with strictly-controlled frequency and amplitude, delivers the signal to needle tip to produce large-quantity ions.

3. It triggers upward leader in advance to meet thundercloud downward leader tens or even hundreds of meters away from air terminal, realizing expanded protection coverage.

Product Features

1. Superior performance, high lightning-striking accuracy, larger protection range and lower lightning current wave-front steepness.

2. Maintenance-free, no power supply needed, safe and reliable, strong wind-resistant capability.

3. Support coordination with lightning online monitoring system, realize IoT-based intelligent and efficient lightning protection solution.

4. Reliable connection and stable performance, comply with latest international standards.

Technical Parameters & Protection Scope

1. Advanced discharge time ΔT: 60μs. Protection radius calculated in accordance with French standard NFC17-102:2011.
2. When effective mounting height h≥5m: Rp (h)=√(2rh-h²+Δ(2r+Δ)); When 2m≤h≤5m: Rp=h×Rp (5)/5.
3. Rp stands for protection radius on target horizontal plane; h means height difference between needle tip and top of protected object; r is 20/30/45/60m corresponding to protection level I-IV; ΔL=V×ΔT represents upward advance distance.
4. Complete dimension parameters and protection radius data are available for different protection grades and installation heights.
