<strong>Trihal</strong>presentation<strong>type</strong><strong>Trihal</strong> is a three-phase <strong>dry</strong> <strong>type</strong> transformer <strong>cast</strong>under vacuum in filled epoxy <strong>resin</strong>.It is this active filler, essentially composed of trihydratedalumina, a fire suppressant, which isthe origin of the <strong>Trihal</strong> trademark.<strong>Trihal</strong> is an indoor <strong>type</strong> transformer (for outdoorinstallation, please consult us).standard<strong>Trihal</strong> complies with standards: IEC 76-1 to 76-5; IEC 726 (1982); CENELEC (European Committee forElectrotechnical Standardization) harmonizationdocument HD 538-1 S1: 1992 andHD 464-S1: 1988/A2: 1991 /A3:1992 concerning<strong>dry</strong> <strong>type</strong> <strong>transformers</strong>.range HV/LV distribution <strong>transformers</strong> from 100 to3150 kVA up to 24 kV.For higher rated power and voltages, pleaseconsult us.<strong>Trihal</strong> <strong>transformers</strong> are supplied in two versions: without enclosure (IP00); with IP31 metal enclosure.The first version do not ensure any protectionagainst direct touch. HV/HV power <strong>transformers</strong> up to 15 MVAand 36 kV. Please consult us.technology and construction<strong>Trihal</strong>, entirely designed and produced by FranceTransfo benefits from two key patented processes: a linear voltage gradient from the top tobottom of HV coil.The very low electrical stress between adjacentconductors makes interlayer barriers unnecessaryand improves the quality of the <strong>cast</strong>ing process. a fireproof <strong>cast</strong>ing system.This technology, patented by France Transfo isimplemented in the Ennery plant in France.The unit’s production capacity allows assuringdelays adapted to clients' needs.quality systemThe certificate issued by AFAQ (FrenchAssociation for Quality Assurance) states that<strong>Trihal</strong> <strong>transformers</strong> are manufactured in accordancewith a quality system in compliancewith the international standard ISO 9001.a technology developed andpatented by France TransfoTRIHALHV/LV <strong>transformers</strong>TRIHAL HV/HV tranformer10 MVA-20kV/6350Vrating up to 140% with AF cooling.(1) reminder on IP protection indexes:1st digit2nd digitdefinitionprotection againstsolid substancesprotection againstliquid(2) reminder on IK protection indexes:scale*IP 310 to 6protection againstsolid substances> 2.5 mm0 to 8protection againstvertically falling waterdropsdefinitionscale**protection againstmechanical shocs0 to 10IP 21protection againstsolid substances> 12 mmprotection againstvertical falling waterdropsIK 7protection againstmechanical shocs 2 Joules* 0 = no protection** 0 = no protectionFrance Transfo3
