ROSS ENGINEERING CORPORATION
Ross High Current Switches are available up to 36,000 amps continuous and over 1,700,000 amps 20µsec 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.

National Technical Systems
Fluid power systems play a critical role in many industries, and are one of the three major forms of power transmission along with electrical and mechanical power systems. In many cases, however, mechanical and electrical methods cannot provide a practical power transmission solution. In these cases, fluid power (whether hydraulic or pneumatic) is often used because it can deliver linear and rotary motion with high force and torque within a smaller, lighter package than is possible with other forms of power transmission. Some of the most common applications of hydraulic systems are in heavy construction and off-highway equipment. Other applications can be seen in aircraft, mass transportation systems (such as trains), construction, mining, agriculture, waste reduction, and utility equipment. The various components (such as valves, actuators, cylinders, accumulators, etc.) that make up these systems must perform reliably and have a reasonable life span. Only a thorough test program carried out under simulated field use conditions can insure that any component part or assembly will meet its original design goals for performance, reliability and longevity. Many internationally recognized organizations have published test standards that apply to hydraulic/pneumatic and fluid power systems and components. Some of these organizations are:
