Sold Per Ft NOS Daburn High Voltage 15KVAC 50KDC Corona Resistant TFE (CRT) Strand Wire #12, 0.302". CRT wire is constructed of a single stranded silver plated copper conductor with Corona Resistant PTFE Insulation. Daburn CRT provides significant performance advantages over traditional HV wire. ? Avoid Corona Problems: Corona Resistant PTFE construction is specifically designed to retard and prevent corona penetration. ? Small Size: You do not need bulky, thick insulation jacketing as used with silicone rubber and polyethylene insulation to get your Hi-Voltage requirements. ? Temperature Variations do not affect wire life: Temperature variations from -90C to +200C have no life effect on the corona resistant PTFE. In addition, there is no stress or crack failure under severe, adverse conditions including mechanical strain, moisture, corona or chemical conditions. ? Wide Operating Temperature: -90C to 200C. For 250C Nickel Plated Copper is available. ? Minimum Life Expectancy: 10,000 hours at the maximum voltage rating Wire used is Mil-Spec QQ-W-343 and Mil-W-16878.
