Cabling system connectors for low radiation environments up to severe accident conditions

Applications

Connectors capable of ensuring long term tightness. For power, instrumentation & control solutions in high radiation and/or high temperature environments.

Key parameters:

Different solutions available: cabling system connectors designed dependent on normal operating conditions and accident condition severity. Can withstand the radiation, pressure and temperature of a design basis accident. Some designs exclude organic compound material.

Product features:

  • State of the art ceramic seals. Qualified resin compound if permitted. LOCA & Post LOCA resistant, severe accident resistant
  • Small dimension, single or multiple contacts
  • Contact pins in nickel or thermocouple material

Plastic coated MI cabling systems

Applications

MI Cable with extruded plastic sheath layer

Key parameters:

All advantages of MI cable robustness
Color coded to facilitate routing
Radiation qualified organic material.

Product features:

  • Plastic extrusion on the metallic outer sheath
  • No electrical contact to prevent coupling in cable tray, for example
  • Allows installation using different colors for different cables
