Long term switchgear performance in an MV substation
depends on 3 main factors
Installation and operation
recommendations
The need of proper installation of the MV cables:
The new cold slip-on and retractable technologies offer ease of installation.
Their design enables operation in polluted environments with harsh atmospheres.
The influence of the relative humidity factor:
the installation of heating resistors is essential in climates with high humidity and
large temperature differences.
Ventilation control:
cubicle ventilation must not be impeded. This is to ensure air circulation within the
switchboard cubicles.
