  • Application of non-sf6 gas gases or gas-mixtures in medium

    When handling gas mixtures, the main difference to SF 6 is that additional efforts for maintaining the correct mixing ratio during filling and reclaiming works are needed. The liquefaction behaviour of single gas components has to be considered which may affect the required gas handling time during maintenance work.
