This request concerns technical acts carried out by Sibelga on the initiative of a customer. Typically, this involves : 

  • de-energising and re-energising (partial or total cuts) customer cabins for maintenance or repair operations;
  • the opening of an equipment or repair cell of the customer cubicle.

In order for the request to be processed, the booth for which the shutdown is requested must be clearly identified by :

  • its number (shown on the pictogram on the booth door). If this number is not indicated on the door, mention the numbers of the adjacent booths on the entry and exit cells; 
  • its precise address (not necessarily the same as the client's address).

Requests must be made at least 3 working days before the desired date. A confirmation fax or e-mail will in any case be sent to the applicant within 2 days of the request.

In the case of replacement or modification of high-voltage equipment (HV cells and transformers), Sibelga will only carry out the switching if it has been notified and has given its prior agreement. If this is not the case, the switching operation will not be carried out and the applicant will be invoiced for travel costs.


These interventions are subject to a charge according to the tariff approved by Brugel.

Details of the type of intervention

Depending on the nature of the work to be carried out, 3 types of intervention may be requested: 

  • Total shutdown: the cabin is completely de-energised, including the network cables. These are de-energised from adjacent cabins. Total shutdown is essential if maintenance or replacement is planned on the loop cells. Sibelga's intervention is limited to operating the switches on the input and output cells. Operating the general protection is the responsibility of the applicant (except where it is made inaccessible by a padlock or other system belonging to Sibelga). It is up to the applicant to provide competent personnel on site to carry out this operation.
  • Partial break: the general protection and the upstream isolating device are opened in order to de-energise the transformer(s). The loop cells remain energised. This type of disconnection can be carried out by the installation manager, provided he has competent personnel. This type of disconnection is suitable for work on the transformer or on the general protection.
  • Cell opening: Sibelga staff come to open one or more padlocked cells. The installation manager can thus carry out a short visual inspection in his presence (30 minutes maximum with only one trip by the technician). No manoeuvres are carried out. This intervention is not suitable for carrying out work.


The costs of our interventions will always be invoiced to the company that requests the disconnection. It is up to the company to recover this amount in the invoice it presents to its customer.


An outage requires preliminary operations such as checking access to adjacent booths, taking parallel between stations, etc.

For this reason, the outage will be invoiced at 50% if it is cancelled less than one working day before the appointment. If it is not cancelled but no representative of the applicant is present at the appointment, it will be charged in full.
