Internal heat is prevented dew type and is prevented putting insulator

The utility model discloses an internal heat is prevented dew type and is prevented putting insulator, including insulating barred body, glow plug, connection lug and flange, insulating barred body both ends respectively with be connected lug and flange and link to each other, the glow plug fix on the flange, the heat -generating body of glow plug inserts in the internal hole of insulating rod. The utility model discloses an insulating barred body adopts isostatic compaction's 95 corundum pottery stick, has compressive strength height, high temperature insulation performance temperature range good, thermal shock resistance advantage such as wide, corrosion -resistant, anti -ageing for prevent revealing the enable with the heating of interior hot type heat -generating body. Connect lug and flange and adopt 2205 duplex stainless steel to make, can effectively prolong its life. The utility model discloses internal heat is prevented dew type and is prevented putting insulator is small, heat stability good, with low costs, long service life to its is original prevents revealing effect and compact insulation system, can prevent the cathode frame swing, can show the reliability that improves high voltage insulation inside the electrostatic precipitator.
