7 Introduction Introduction This spare parts list has been compiled to help you with procurement of spares. To obtain trouble-free deliveries you should note a few things which are explained in the following text. The breakdown level and general contents of this list have been worked out to cover normal customer requests. Our spares sales people will be happy to assist if you require any specific item that is not included in the list.. Type Designation and Serial Number The rating plate on the on-load tap-changer (OLTC) shows the type and serial number of the device you are ordering spares for. It is important to have this information, because the manufacture of parts gradually changes as materials and manufacturing technology improves. ABB makes every effort to supply spares that should fit your requirements. Some parts of later manufacture than those you are replacing may need some adaptation to fit into your device. Our spare parts sales people need to know the type designation and serial number to supply exactly what you require..2 Item Number Item numbers are shown on the drawings and lists. As you will observe, one item number is used for several items of the same general type. These items have a specific specification for each and every variant of OLTC, hence you need to specify type and serial number in addition to the item number to obtain the appropriate spare..3 Name of item The name should be specified when ordering to make sure the right type of item is ordered..4 Quantity The figures given represent the number of items that are fitted to one OLTC..5 Remarks Information pertinent to different variants of the OLTC is given in this column. Your model should be one of those shown. 7

8 2 General Arrangement 2 General Arrangement The general arrangement of an UC type on-load tap-changer is shown in fig.. 2. Standard Spare Parts The rugged design of ABB OLTCs means that only the fixed and moving contacts of the diverter switch might require replacement during lifetime of the transformer. This spare parts list tells you the part number of the contacts when ordering for your replacement requirements. 2.2 Special Spare Parts If you need parts other than the contacts in the lists, our staff will be happy to assist you. Please use fig. as a reference when discussing your requirements. As usual, the type designation and serial number are essential for ordering. 8
