Trihal complies with the most stringent standards, thereby delivering optimal security :

According to IEC 60076-11,Trihal underwent in turn C2 and E2 tests at the CESI (Italy) in June 2007. A complete coil was then taken as a sample to be submitted to the F1 flame-proof test at the CNPP (France)...Respective certificates A7011679 and PN077347

Resistant to load variations and overloads : C2
Operation, transportation and storage down to - 25°C, and up to -50°C for Trihal freeze
Outdoor installation with specific enclosure
Resistance to thermal shocks

Insensitivity to extreme environments : E2
Resistant to no conductive pollution,
Resistant to condensation
Resistant to both simultaneously

Immediately Self-extinguishing : F1
The F1 test is obligatory in some standards (NFC 52-115 in France)
Self-extinguishing once the flames are put off
Halogen product free
No toxic or thick fumes

Demonstrated robustness
Test carried out at the SOPEMEA in December 2006 - certificate EHL 08515
Mecanical performance against vibrations reproducing the stresses produced by Richter Force 7 seismic activity for 4 x 20 seconds

Worry-free operation
Excellent resistance to short-circuits
Improved lightning resistance
Level of partial discharges ≤10 pC
