Large quantity of non IEC standard, EHV/HV GIS in power systems are still under operation. When there is a requirement of extension/testing of old GIS or connection of a new cable feeder, having an IEC standard termination is not possible without an adaptor. PTE has an experienced team of engineers to design, manufacture and install adaptors for old non IEC type GIS to new IEC standard interfaces. We have successfully designed, manufactured and installed huge number of adaptors in the region.
