HV Rotary Switches
B-1003
A key feature of our rotary switches is their simple mechanical design which results in conservative stress levels for trouble-free, long life use. In addition, each rotary switch has a reinforced chassis design utilizing G-10 or G-11 fire retardant anti-tracking coated epoxy glass insulation. G-7 silicone glass is used for special applications where RF or high temperatures are involved. Heavy duty contacts, specifically designed to minimize corona in the Ross rotaries, are made of highly conductive yet weld resistant alloy with high contact closing force. This high force gives our rotary switches high momentary current capability and a reputation for their ability to withstand high shock and vibration as well as other severe environmental conditions. Ratings to 150kV, to 200A. When immersed in insulating oil, fluid or gas, the voltage withstand value is at least doubled and the interrupt capability is much greater. In a gas atmosphere, no modification is required. However, immersion in oil or fluid may require modification in some cases, at an extra cost (optional). Each unit is either manually or electrically operated. One SPDT contact is standard on most units. The auxiliary contact is used as an interlock for protection against "Switching Hot".

Insulating Oil Testers
The main functions of electrical insulating oils are heat dissipation and reliable insulation of energised parts of electrical installations. During the normal operation, moisture and other impurities penetrate into insulating oils, leading to a deterioration of their dielectric properties. This in turn may result in catastrophic failures of critical electrical equipment.

*High Current Switches
B-1002
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.
