Preparation woks for an installation may be defined as in-situ investigations, obtaining permits from applicable offices and making projects according to these permits for satisfying power demands of houses, factories and other industrial facilities. After this step, we install pole-type or building-type transformers according to the project, we start them and have acceptance from relevant offices. Finally, we deliver the facility to our customer in a seamless way. Then, we undertake after-service power responsibility for the facility and conduct technical and occupational safety checks periodically and at least once each month for the said facility of the company. We inform the employer and we deliver the required data and documents to him as well as we inform the employees. We make the required notifications about lubrication change of the transformer and technical revisions for it.
