The ground insulation consists of required number of resin poor mica tape layers depending upon required insulation level. The resin poor mica tapes are applied all over the stretched coil. All insulated coils are inserted in core slots, wedged & laced. The wound core is put in VPI tank & vacuum is applied to remove the...

The standard insulationsfor HT wlndings employs Class F' mate riais throughout. However class H insulation also provided on request. After the insertion of insulatf coils, the compl㯨te wound stator pack undergoes a vacuu pressure imprgnation process and curing. Addition processes are carried out to protect the coils against coroi discharges for...

Cable boxes are provided to house the main terminals on one side and neutral terminals with provision for mouting current transformer on the other. The standard main terminals box is air insulated, designed for simplicity, reliability and ease of connection. Alternatively...

During winding procedure, resin is applied on the pole body as well as between conductor layers. The wound coil is subsequently cured under heat and pressure. For salient pole generators in higher frame size insulation between turns of field coil consists...
