  1. Suggested Engineering Changes to Modular Coil Lead Area James H. Chrzanowski June 13, 2006

  2. Lead Area Design Changes • Lead Area upper chill plate • Lead Area lower cladding • Improve tracking distance hardware to jumpers • Eliminate floating Hardware • Jumper studs • Power bus joint

  3. Lead Area Chill Plates - If possible eliminate upper chill plate - Difficult to insulate - Potential problem in future??

  4. Lead Area Cladding- Lower • Replace lower cladding in lead area with G-11cr [eliminate floating pieces]

  5. Power Bus Tie-in Area • Improve tracking distance- install barrier • Eliminate floating through bolts- tie studs to one side of joint

  6. Improve Tracking Distance • Improve tracking distance • Install 032 in. thick G-11cr insulator under jumpers covering bolts

  7. Lead Area Floating Hardware -Link the [3] jumper studs to the bottom jumper using G-11cr [1] insulator and copper plate [2] -Tie plate to jumper 1 lug [3] using wire 2 1 3
