EPD: Medium voltage gas insulated switchgear with two load-break switch units and one circuit-breaker unit, including packaging, 24kV, SafeRing/SafePlus AirPlus CCV Arc Classified (ABB Electrification Norway AS)
ABB SafeRing/SafePlus Switchgear is a medium voltage gas insulated ring main unit for secondary distribution. The main function of the switchgears is to establish and cut off the supply of a downstream installation from an electrical and/or mechanical control and to protect people and premises at risk of fire or explosion against insulation defects. SafeRing/SafePlus can be supplied in a number of different configurations suitable for most switching applications in 12/24 kV distribution networks. SafeRing/SafePlus AirPlus 24kV type CCV Arc Classified switchgear consist of two load-break switch units (C-module) plus one circuit-breaker unit (V-module). The manufacturer proclaims a minimum product service life of 30 years but the calculations are based on 20 years as the PCR dictates. The functional unit of this study is described as 1 piece of SafeRing/SafePlus AirPlus 24kV type CCV Arc Classified including heat loss during a 20 year product lifetime. The functional unit is IAC classified.
