MR Germany is one of the reputable and industry-leading companies in the manufacture of power transformer equipment for OLTC pulsators as well as intelligent CBM monitoring systems. According to my experiences of about 4 years in the Iranian electricity industry, in addition to the appropriate quality of equipment, one of the important factors of satisfaction with MR company is proper after-sales service. Especially cooperation in critical times such as the imposed war and oppressive economic sanctions against Iran. In addition, I have always seen updating or changing the design (Modification) of some old parts or systems used, according to the recommendation of the MR manufacturer in the equipment of Iran's electricity industry (and other countries). I wish this company more success, especially the after-sales service of this company in Iran.
