Fire-Safe GSM Transformer (AS2067 Enhanced Protection, FM Approved)
EXNOVO improves the reliability and efficiency of energy for indoor and outdoor applications through extensive development and certification, which have resulted in the GSM transformers. The GSM technology combines the efficiency of a liquid-insulated transformer with the superior safety of a dry-type transformer.
The GSM is a hermetically sealed, less-combustible liquid-immersed transformer with enhanced protection that complies with AS2067. A reference unit of the GSM transformer undergoes destructive testing, including but not limited to transformer tank strength, pressure resistance, fire suppression capabilities and physical performance. There are only two companies in Australasia that are certified to manufacture enhanced protection transformers, such as the GSM, that comply with AS/NZS 60076 and FM Approval Standard 3990 .
Some important elements that can affect the performance and reliability of transformers are environmental pollution, atmospheric corrosion, humidity, and resistance to ageing. A summary of the effects and typical failure resulting from environmental parameters are shown in Figure 1.
