W STANDARD SPECIFICATIONS
- A 1/2″ diameter SUS hose is used as standard to attach to the direct water-cooled resistors. Upon request, we can offer other hose joint.
- Use pure water with a resistivity of 1 MΩ⋅cm or higher (an electrical conductivity of 1 µS/cm or lower) as the cooling water.
- Keep the water pressure at 0.59 MPa or lower.
- Use 4-mm-diameter bolts to attach these resistors. Tighten the bolts at about 0.5 N⋅m.
- Use a worm gear hose clamp, and tighten it at 1 to 1.5 N⋅m.
- Allow water to flow at a rate of at least 5 ℓ/min. Do not interrupt the flow. We recommend installing a safety circuit.
- Mount the resistor vertically, and allow water to flow from the bottom to the top. (The same applies to the simultaneous use of several resistors.)
- Keep the surge voltage at 1800 V or lower (250 V/cm for the effective length of the resistor).
