Title: Hot & Pinched Post by: K6JEK on July 08, 2005, 01:30:42 PM I need to replace some wiring in my CE 100V. These wires are prone to getting hot & pinched. What's better vinyl or teflon insulation?
The details: The wires from the fan (110 VAC) are routed between the power transformer and the edge of rectifier heat shield, two chrome plated steel plates with sharper-than-you'd like edges. There is only about 1/8" clearance and can be less. The transformer mounting tabs have slots that allow the clearance to be zero. I discovered my fan wires had been sliced almost all the way through the insulation, in fact I can see copper. I was nearing an exciting moment. I moved the power transformer, giving a bit more clearance. Next I'll replace the wires. But with what? Nifty teflon stuff I have, plain old vinyl, or something else?
