sf6 maintenance System working principleAbnormal LeakageInternal FaultExternal FireThe method of risk assessment is similar to that used in section "leakage from SF6 – filled equipment" which deals with normal leakage. The same case study data will be used for high and medium voltage situations. In the calculations that follow it is assumed that all of the SF6 in one circuit breaker escapes suddenly and it is again assumed that the switch room is sealed and that ventilation is inoperative. (see figure 1).

Its function is the same as a rail pad, but it is thicker than rail pad. For the high speed or high load train, it is a necessary rail fastener . Properties of rail insulators. The insulators apply to rails such as 60kg (UIC) rail, 52kg rail, 136RE Rail, 90R, 75R, 50R, 60R etc. The rail insulator is mainly made by injection molding production, and it is mainly composed of Nylon 6 or Nylon 66 with glass filler content 20% to 35% depending on specification.

Electronic band theory (a branch of physics) dictates that a charge flows if states are available into which electrons can be excited. This allows electrons to gain energy and thereby move through a conductor such as a metal. If no such states are available, the material is an insulator.
