UL 3257 is a UL-certified silicone ignition wire rated 250\u00b0C, 10 kV AC and 25 kV DC. The stranded nickel-plated copper construction is intended for internal high-voltage leads, with separate voltage ratings for AC and DC circuits.<\/p>\n
Two silicone wall options are listed across 22\u201312 AWG: 5\/64 in and 7\/64 in. The larger wall increases the finished diameter, weight and minimum bend radius even when the conductor size stays the same. The two complete tables make that difference visible, so an ignition lead can be selected against the terminal boot, entry opening and available bend space rather than by AWG alone.<\/p>\n
For burner or oven ignition assemblies, record the waveform and operating voltage before choosing the construction. Protect the lead from repeated flexing and use terminations that suit the full voltage and temperature duty. The silicone construction is not intended for immersion. Where a thicker wall is requested, make sure the assembly drawing also allows the larger outside diameter and bend radius.<\/p>\n
