All types of disconnector manufactured by MLE can be converted to switch disconnectors by the addition of MLE Loadmaster interrupter heads.
Interrupter heads are available in two sizes; 12kV and 24/36kV.
Arc interruption within the Loadmaster is achieved by a hard gas generated at high pressure in the space occupied by the arc column. The hydrogen and carbon dioxide gases which are generated by thermal action on the acrylic liner acts to de-ionise the gas produced by the arc and improve its electric strength.
