installation and operationrecommendationswitchgear ageingwithstandinanMVsubstation depends on 3main factorsH The need for properimplementation of connections:the new cold slip --- on andretractable technologies offer easeof installation, thereby promotingwithstand over time.Their design enables operation inpolluted environments with harshatmospheres.H Theinfluenceoftherelativehumidity factor:installation of heating resistors isessential in climates with highrelative humidity and largetemperature differences.H Ventilation control:the grids must be sized accordingto power loss in the substation.These grids must only be placednear the transformer, so as toprevent air circulating on the MVswitchboard.operationWe strongly recommend that youcarry out at regular intervals (atleast roughly every 2 years) afewoperating cycles on theswitching devices.Outside normal operatingconditions (between --5°C and40°C, absence of dust, corrosivegas, etc.), we recommend that youcontact our Groupe SchneiderElectric service centre in order toexamine the measures to be takento ensure proper installationoperation.Our service centre is at yourdisposal at all times:H To conduct an installationdiagnosis.H To suggest the appropriatemaintenance operations.H To offer you maintenancecontracts.H To suggest adaptations.7896779EN revision : 01 13
