Rugged Cable Manufacturers

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."

Specifications

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.
