| Ross High Current
Switches are available up to 36,000 amps
continuous and over 1,700,000 amps 20 µsec RC pulse, with
voltage ratings of 6 volts to 400KV peak test. Standard
Ross high current switches are built with 80 to 120psi air
cylinder actuators. Air cylinder or motor operated for
high contact force. Arcing contacts optional for closing
current. G-10 epoxy glass laminate is standard insulation
on most models. G-7 silicone glass is used on models available
for RF applications above 100KHz. Most Ross high current
switches are available with additional lengths of insulation,
where the high voltage contacts need to be spaced at a greater
distance from the actuator and control circuit. Voltage
withstand value is at least doubled and the interrupt capability
is much greater when high current switches are immersed in
insulating oil, fluid or SF6 gas. For gas atmosphere, no
modifications are necessary; however, oil or fluid
immersion requires modification at a slight extra cost. |
