Twisted Pairs
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 multiple pair control cables. Conductors are of tinned copper strand with .015” vinyl primary insulation for use up to 105°C per MIL-W16878/2*. Insulated for 1000 volts working voltage. Conductors are color coded using 10 standard basic colors, plus spiral tracers on white
All pairs are planetary cabled and contra-helically laid with a Mylar tape serve over the 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. Also available with Neoprene to MIL-R-6855 Class 2 Grade 60 specification, non-U.L. applications. Also available with Neoprene jacket as a custom product. Consult factory for details.
"*Cables are U.L. STYLE 2343 or 2344, rated 80°C, and CSA CERTIFIED for 105°C as described below. U.L. and/or CSA certification furnished only when requested."
Insulated wires also meet U.L. Style 1007 or 1569 as appropriate for gauge.
Identical to National’s NW-Series Cables except offered as twisted pairs.
"NWPC cables in 16 gauge are similar to NWP series but utilize materials to qualify for CSA cetification for AWM II A/B 105ºC service at 300 volts as well as styles 2343 and 2344.NWPC cables are not stocked and are subject to minimum run quantities."

Insulation Breakdown Voltage | Greater than 5000 volts AC RMS, 60cps. | |
UL Voltage Rating | 300 volts RMS AC (appliance use) -- 600 volts RMS AC (electronic use), 600 volts RMS AC (electronic use) | |
CSA Voltage Rating | 300 volts RMS AC (appliance use) | |
Military Voltage Rating | 1000 volts RMS | |
Capacitance | Nominal capacitance wire to wire for a pair ranges from 27 to 40 pf/ft Capacitance from both wires tied together measured to all else in common ranges from 35 to 60 mmfd/ft. dependent on gauge and position. Overall shield has negligible effect on W-W capacitance. | |
Insulation Leakage Res | 200 megohms/1000 ft. min. at 500 VDC from any conductor to all else in cable. | |
Sheath Leakage Res | 10 megohms/1000 ft. min. at 500 VDC form overall shield through sheath to outside world. | |
Usable Temp. Range | Suitable for continuous use from -40°C to +105°C. | |
Cold bending Capacity | All cables are suitable for flexing to a circle diameter of 6 cable diameters from +105°C to -20°C. Recommended flex diameter should be greater than 20 cable diameters for flexing at -40°C. For continuous flexing application consult the factory. | |
