REQUEST MORE INFORMATION

The specific function of WAT Franklin Plus E.S.E Lighting conductors^® PDC lightning rod is producing an upward stream of ionized particles pointed to clouds that will channel the eventual electrical discharge from its origin.

There is a different potential between the discharger (that has the same potential than the air around it) and both the air terminal tip and the deflection ensemble (they have the same potential than earth).

This difference increases as atmospheric potential becomes higher because of the imminent lightning stroke.

Characteristics

High temperature resistance
High resistance to weather and corrosive atmospheres

The capture terminal of WAT Franklin Plus E.S.E Lighting conductors^® PDC fits the following technical specifications:

It has a double ESE (Early Streamer Emission) system.
An early streamer device that produces the upward emission.
An electro atmospheric condenser.
An atmospheric accelerator.
An insulation system certified by the General Testing & Research Laboratory of the Generalitat of Catalunya (LGAI).
An external structure made from stainless steel AISI 316L.
Early Streamer Emission system made from stainless steel AISI 316L and polyamide PA66.

Its effective operation in any atmospheric condition and environment is thus guaranteed.

Protection radii calculated according to: Norm UNE 21.186:2011 & NFC17.102:2011 (These radii of protection have been calculated according to a height difference of 20 m between the tip of the lightnin grod and the considered horizontal plane).

WAT Franklin Plus E.S.E Lighting conductors® PDC, fulfils the requirements contained in norms:

IEC 62.305
UNE 21.186:2011
NFC 17.102:2011
EN 50.164/1

In addition to all the specifications outlined for this type of components in the High Voltage Regulation by the Spanish Ministry of Industry and Energy. Industrial registration num. 150.032 (Spanish Ministry of Industry and Energy). Manufactured from 1984, it is the first lightning rod provided with a non electronical ESE system that fulfils the requirements contained in the norms UNE 21.186:2011 and NFC 17.102:2011.

Supported current test in the BET, Blitzschutz & EMV Technologiezentrum (Menden, RFA) Laboratory and in the ISKRA ZASCITE Laboratory - Surge Voltage Protection Systems, Engineering and Cooperation.

Test of insulation resistance, at the General Testing & Research Laboratory (LGAI) of the Generalitat of Catalunya.

Certificate of fulfillment of the particular regulation of brand AENOR, issued by LABELEC High Voltage Laboratory.

Certificate of supported current, issued by LABELEC High Voltage Laboratory.

Certificate of insulation in rainy conditions, issued by LABELEC High Voltage Laboratory.

Product certificate issued by the Bureau Veritas Certification entity.

The capture terminal of WAT Franklin Plus E.S.E Lighting conductors^® PDC should follow the prescriptions of the norms NFC 17.102:2011 (or Norm UNE 21.186:2011) and EN 62.305:2011, and should take into account the following:

The tip of the lightning rod should be situated, at least two meters above the highest building to be protected.
For its installation on a mast, the corresponding head-mast adapter is needed for the lightning rod.
The cabling on the roofs should be screened protected against surges and connect to ground the metallic structures present within the safety zone.
The lightning rod should be connected to a grounding point by way of one or various conducting cables which will go down, whenever possible, the exterior of the construction with the shortest and straight possible trajectory.
The earth termination systems, whose resistance should be the lowest possible (less than 10 ohms), should guarantee the most rapid possible dispersion of the lightning current discharge.
