Incoming configuration ofMVcables

Intended for cables up to 240 mm².

Not recommended for 630 mm² cables.

MVcablesincoming

Civilengineeringwithmaintenancespace

Some recommendations are given below.

Other incoming configurations are possible, particularly if there is greater clearance under the FUs.

Note: if the cable box is used, adapt the depth of the maintenance space.

Should you have questions concerning a configuration, contact your nearest SchneiderElectric representative.

The civil engineering execution and the installation of MV cables must take several inputs into account:

- The bending radius of the cables- Cable slack to push and pull them- Cable handling, according to incoming configurations and free cable length from its point of insertion in the maintenance space.

Operationandmaintenance

Needforgoodimplementationofcable-endrestoration:

New cold retractable or slip-on technology offers ease of installation that favours resistance over time.

Their design allows them to used in polluted environments with harsh climatic conditions.

Impactoftherelativehumidityfactor:

Installing a heating device is essential in climates with high relative humidity levels and major temperature differences.

Theswitchgear’sresistancetoageinginanMVsubstationdependson3mainfactors:

Ensure that draughts and / or thermal shocks are avoided in all cubicle compartments in order to avoid the creation of dew points (sources of partial discharges).The equipment must be installed in conformity with the relevant IEC standard. Outside of these normal usage conditions, we recommend contacting Schneider Electric to determine the operations to be carried out as well as their frequency according to the actual service conditions.

Ventilationcontrol:

Grid size must be suited to the power dissipated in the substation. These grids must be placed exclusively in the vicinity of the transformer, in order to avoid air circulation on the LV switchboard.
