Apollo GDS Format Guide. Description: A comprehensive list of Apollo formats. Strongly recommended as a companion to the Comprehensive and Conversion courses. This book lists all formats taught in the VIASINC Apollo courses or available in the Apollo emulator. Formats are organized by subject, and are shown alongside a brief description.
Aluminium Alloy-Commercial Alloy - 6061 - T6 Extrusions. Aluminium alloy 6061 is a medium to high strength heat-treatable alloy with a strength higher than 6005A. It has very good corrosion resistance and very good weldability although reduced strength in the weld zone.It has medium fatigue strength.luminium Alloy-Commercial Alloy - 6061 - T6 Extrusions. Aluminium alloy 6061 is a medium to high strength heat-treatable alloy with a strength higher than 6005A. It has very good corrosion resistance and very good weldability although reduced strength in the weld zone.
Sulfur Hexafluoride (SF6)Gas Handling. Sulfur hexafluoride (SF6) in its pure state is inert, nontoxic, odorless, nonflammable and colorless. Ithas excellent arc quenching properties and exhibits exceptional thermal stability. SF6 has exceptionallygood insulating properties and at atmospheric pressure has 2.5 times the dielectric strength of air. SF6 gas at 289.6 KPa (42 psig) has the same dielectric strength as transformer oil. Sulfur hexafluoride remains a gas without liquefying down to -34.4Â°C (-30Â°F) at the gas pressurenormally used in the puffer type breaker. The density of SF6 is about five times that of air (molecularweight equal to 146).
