PC37.122.3 - Guide for Sulphur Hexafluoride (Sulfr hexafluoride) Gas

This guide describes aspects of the handling of sf6 gas gas used in electric power equipment, such as gas filling, recovery, reclamation, testing, quality analysis and recycling, in order to keep the gas permanently in a closed loop system and to avoid any release into the environment.Get price

SF Maintenance Equipment Fundamentals

The main component in any gas recovery system is the compressor. It is used to transfer SF 6 from the GIE to the storage tank. Depending on design, it may also be used to transfer gas from the storage tank back to the GIE. There are several compressor designs that are currently used: oil-based, oil-free, and oil-less.Get price

Air War Korea, 1950-53 - Air Force Magazine

1950195119521953June 25:North Korea invaded South Korea. Simultaneously, North Korean troops made an amphibious landing at Kangnung on the east coast just south of the 38th parallel. North Korean fighter aircraft attacked airfields at Kimpo and Seoul, the South Korean capital, destroying one USAF C-54 on the ground at Kimpo. John J. Muccio, US ambassador to South Korea, relayed to President Harry S. Truman a South Korean request for US air assistance and ammunition. The UN Security Council unanimously called for a cease-fire and withdrawal of the North Korean Army to north of the 38th parallel. The resolution asked all UN members to support the withdrawal of the NKA and to render no assistance to North Korea. Maj. Gen. Earle E. Partridge, who was commander, 5th Air Force, but serving as acting commander of Far East Air Forces (FEAF), ordered wing commanders to prepare for air evacuation of US citizens from South Korea. He increased aerial surveillance of Tsushima Strait between Korea and Japan. The...Get price
