installation and operation recommendation
switchgear ageing withstand in an MV substation depends on 3 main factors
The need for proper implementation of connections: the new cold slip---on and retractable technologies offer ease of installation, thereby promoting withstand over time. Their design enables operation in polluted environments with harsh atmospheres.
Ventilation control: the grids must be sized according to power loss in the substation. These grids must only be placed near the transformer, so as to prevent air circulating on the MV switchboard.
The influence of the relative humidity factor: installation of heating resistors is essential in climates with high relative humidity and large temperature differences.
operation
We strongly recommend that you carry out at regular intervals (at least roughly every 2 years) a few operating cycles on the switching devices. Outside normal operating conditions (between --5°C and 40°C, absence of dust, corrosive gas, etc.), we recommend that you contact our Groupe Schneider Electric service centre in order to examine the measures to be taken to ensure proper installation operation.

maintenance instructions
preventive maintenance, cleaning instructions and power---up
We strongly recommend that you carry out at regular intervals (at least roughly every 2 years) a few operating cycles on the switching devices.
If necessary: contact the Schneider Electric group service centre.
CAUTION
CAUTION
Never lubricate the disconnector operating mechanism. If necessary: contact the Schneider Electric group service centre. In normal operating conditions (temperature between --- 5°C and 40° C) no special maintenance is required.
Never use solvents and alcohol. We recommend that you inspect each compartment (cable, fuse, busbar)* at regular intervals according to environmental conditions.
If the insulating parts are dusty, that you remove the dust using a dry cloth.
example :
In harsher conditions (aggressive atmosphere, dust, temperature less than --- 5° C or greater than 40° C) consult the nearest Schneider Electric service centre.
