Solutions for the IEEE Market
With an offering of comprehensive range for IEEE style OIP condenser bushings from 25 kV up to 161 kV fully compliant to IEEE C57.19.00/01 standard, customers catering to the rapidly expanding power infrastructure demand in USA/Latin America market have come to appreciate supplies from an established global brand like YASH, which possesses the capability to offer interchange able solutions.
Recent exports for the IEEE market include 34.5 kV 1200 A 534BCT OIP condenser bushings to a transformer customer in Korea, a prestigious end project in USA, as well as 69 kV 1200 A 534BCT OIP condenser bushings for a discerning transformer customer in Ecuador, again for transformer export to USA. The bushings are compatible and will be utilized for online monitoring by using a reputed European condition monitoring system by the end customer.
Recently, YASH executed a contract for a major thermal power generation plant in USA supplying 36 kV 16,000 Ampere High Current Bushings, in addition to several OIP bushings supplied to the Latin American region with support from The H-J Family of Companies.
Through our established bushing retrofit business, we exported a large shipment of YASH made 36 kV 16,000A High Current Bushings were also recently exported to Turkey, for replacing existing transformer bushings of another reputed global bushing supplier. The bushings were installed on 270 MVA Generator Transformers at a 2×660 MW thermal power plant in Turkey. The retrofit bushings were customized to meet the mounting and termination needs of the end user, and were executed in record lead times in-spite of pandemic related lockdown conditions with full satisfaction to the customer.
In 2020, YASH successfully executed High Voltage OIP bushings with polymer/silicone insulator for a renowned transformer OEM in Italy, for an AC project run by the utility ENEL, with many more projects in the pipeline for the Italian market.
