PLS-24 similar with ABB SFG an indoor high-voltage SF6 load switch, an switchgear with the rated voltage of 24kV, adopted with SF6 gas as an arc-extinguishing and insulation medium, including the three contactors for switching-on and switching-off and to-ground, and is characteristic in its small volume, its convenient installation and operation and its the great adaptability with surroundings.
There are two kinds of load break switch for PLS-24 (K type single spring-operated spring mechanism) and PLRS-24 ( A type double-spring operated mechanism). PLRS-24 can be formed into switch-fuse combination and with control function. PLS-24 of an indoor high-voltage SF6 load switch and PLRS-24 load switch plus fuse combination are complied with the standards of GB3804-1990, IEC60256-1,1997, GB16926,IEC60420 etc.
Service conditions:
