OCP2 Open Cage Polymeric Surge Arresters - Class 2

Class 2 Open Cage Polymeric
Class 2 Open Cage Polymeric
  • Protection of MV networks, sensitive equipment and substations from lightning and switching surge related over-voltages in areas with relatively high iso-keraunic levels.
  • Direct moulded housing to prevent moisture ingress
  • Low residual voltages
  • High-energy handling
  • Superior TOV performance
  • Safe non-shattering short current behaviour to higher current levels
  • The crimped structural construction ensures light weight product with optimal mechanical strength
  • Maintenance free
  • Hydrophobic silicon housing (tracking and erosion resistant)
  • Tested in accordance with IEC60099-4 at independent accredited laboratories

Technical Data

Specification should include

  • Material (porcelain or Polymeric)
  • Lightning impulse withstand voltage (BIL)0Um kV r.m.s - Lightning impulse withstand voltage of equipment (BIL) kV r.m.s
  • Creepage distance (mm/kV)
  • Maxiumum continuous operating voltage
  • System temporary over voltage
  • System temporay over voltage duration
  • Umax (maxiumum system phase to earth voltage in system) (kV)
  • Duty rating (kV) – “Duty cycle voltage” is a term used in IEEE standards; IEC equivalent would be as follows: Surge arrester rating (kV)
