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.
6061 is a precipitation hardening aluminium alloy, containing magnesium and silicon as its major alloying elements.Originally called Alloy 61S, it was developed in 1935. It has good mechanical properties and exhibits good weldability. It is one of the most common alloys of aluminium for general purpose use.It is commonly available in pre-tempered grades such as 6061-O (annealed) and tempered grades such as 6061-T6 (solutionized and artificially aged) and 6061-T651 (solutionized, stress-relieved stretched and artificially aged).t is one of the most common alloys of aluminium for general purpose use.

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).
