M Bushing conductor studs pressure and vacuum tight 1 Stud-type bushing with threaded sleeve 2 3 Description Technical data Industrial processes often take place within closed containers, under increased pressure or even vacuum conditions. It is therefore of utmost importance that no media leakages or pressure/vacuum drops occur when electrical power or signals are led through the container wall. Our BARTEC pressure and vacuum sealed stud-type bushings provide a simple and cost-effective solution to this problem. The stud-type bushings essentially consist of a threaded metal sleeve and the stud forming one block by means of a creepage-proof insulation material. The electrical connection can be made by the user himself with conventional connection systems. The seals can withstand pressures from 10 mbar abs. to 63 bar depending on the type used for the installation. Depending on their field of application, BARTEC pressure and vacuum sealed stud-type bushings can be used at temperatures of -40 °C to +150 °C rising to short-term +180 °C. Our BARTEC studtype bushings can also be used under conditions that differ from the basic technical data listed below. They are not approved for the use in hazardous areas. æ Basic Version 4 Nominal voltage 400 V 2) Stud thread M8 to M16 Temperature range -25 °C to +100 °C 5 Nominal pressure 10 mbar abs. to 63 bar at RT 1) 3) Test pressure 80 bar at RT 6 Versions deviating from the basic technical data on request Dimensions Selection chart Nominal current 7 4) ∅c 100 A 250 A 315 A f g at +25 °C ambient temperature Dimensions in mm AF 41 55 60 d 100 150 160 35 50 55 f k R 1 1/2’’ c 20 M16 R 1 1/4’’ e (d) M12 R 1’’ 30 50 55 g e M8 b 10 a g 03-0330-0187-08/08-BCS-200663/4 40 40 30 36 36 k a b 22 AF 35 50 50 Order no. 37-9119-A019/70E2 37-9119-A019/70E1 37-9119-A019/70E4 1) RT = +25 °C lower, depending on vacuum 3) depending on outer seal 4) stud: brass 2) 183 200663_3_4.pmd 3 12.11.2010, 12:16
