Mil Spec UL AWM
Recognized Style 2343 or 2344 and CSA Certified AWM II A/B
National Wire & Cable Corp. manufactures a complete line of extra heavy duty multi-conductor control cables. Conductors are of tinned copper strand with .031” wall of polyvinylchloride primary insulation for use up to 105°C. Per MIL-W-16878/3, insulated for 3000 volts working voltage
Conductors are color coded using 10 standard basic colors, plus spiral tracers on white per MIL-STD-681.
All conductor are planetary cabled and contra-helically laid for optimum flexibility, with a Mylar tape serve over cable bundle. Shielded cables have a tinned copper braid overall, of 85-90% coverage per MIL-C-7078, and braid angles below 40° for easy pushback.
The outer jacket is black, abrasion-resistant 105°C vinyl meeting MIL-I-631 Type F. This material is self-extinguishing and fungus resistant. Neoprene to MIL-R-6855 Class 2 Grade 60 specifications also available on special for non-U.L. applications.
"Cables are U.L. STYLE 2343 or 2344, rated 80°C, and CSA CERTIFIED for 105°C U.L. and/or CSA Certification furnished only when requested."
Identical to National’s NW-Series Cables except offered as twisted pairs.
Insulated wires also meet Style 1015.
|Insulation Breakdown Voltage||Greater than 12000 volts AC RMS, 60cps.|
