The PDC Sigma + is a lightning protection device that intercepts lightning up to a distance of 107 meters. Its Priming Device actively captures lightning, providing more safety than a traditional lightning rod . This system stores the electrical energy of the atmosphere, and releases it in the form of an ascending tracer, capturing the lightning at a greater height.
These protection radii are calculated and tested based on CTE SU8, UNE 21186, NCF 17102 and NP 4426 standards .
*Radii of protection in meters for a tip height of 6 meters in relation to the plane to be protected.
Tests and trials
The PDC Sigma + has successfully passed the following tests in accordance with the UNE 21186, NFC 17102 and NP 4426 standards:
- Dimensional analysis: ensure that dimensions are based on standards.
- Current resistance: certified 200 kA (10/350 μs) – Ensures operation in very energetic discharges.
- Adverse atmospheric conditions: certificate of resistance against saline mists and humid sulphurous atmospheres.
- Priming advance: guarantees the protection radius.
