NQP SERIES
Cabled Twisted Pairs Conductors
Mil Spec, U.L. AWM
Recognized Style 2464 and CSA Certified AWM II A/B
National Wire & Cable Corporation manufactures a complete line of highly flexible micro-miniature low-voltage instrument control cable .These are available as cabled pairs or singles, with optional overall shield of either foil with drain or a braided shield.
Conductors are stranded tinned copper with .010” wall of tough extruded polyvinyl chloride primary insulation, rated for 300 volt use at +80°C under U.L. style 1061*. All are color coded using ten standard colors plus white with stripes per MIL-STD-681.
Conductors are planetary cabled and helically laid for optimum flexibility, with a barrier under braids. Shielded cables have a tinned copper braid of 90% coverage per
MIL-C-7078, with braid angles below 40° for easy pushback; or have 100% coverage foil shield in intimate contact with a drain wire for easy termination.
Outer jacket is highly flexible abrasion-resistant gray polyvinyl chloride thermoplastic, meeting the requirements of U.L. style 2464. **U.L. & CSA certification furnished.
Military certification furnished only when requested.
All materials are flame retardant and fungus resistant. Standard Putups: 500 and 1000 ft. No-deposit reels. For shorter quantities or specific lengths, consult factory.
*Wire also meets MIL-W-16878 rated 600 volts, +105°C.
**Jacket material is military rated for 105°C; meets MIL-l-631, Type F.
Meets E.l.A. Standards RS-232 for 18-24 gauges.
Specifications
| Insulation Breakdown Voltage |
Greater than 3400 volts AC RMS, 60cps. | |
|
| Capacitance |
Nominal capacitance from a wire to all else in a cable ranges from 25 to 45 pf/ft at 1 kc, depending on gauge and position. | |
|
| Insulation Leakage |
200 megohms/1000 feet minimum @ 500 VDC form conductor to all else in cable. | |
|
| Sheath Leakage |
10 megohms/1000 feet minimum @ 500 VDC from shield or conductor group through sheath to ground. | |
|
| Bending Characteristics |
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 applications consult the factory. | |
|
| Temperature Range |
U.L. rating: +80°C per U.L. style 2464. - Military: Continuous use from -40°C to +105°C. | |
|
| Foil Shielded Cables |
The nominal over-all diameter of foil shielded cables will be .006” greater than the non-shielded cables of the same conductor count and wire size. | |
|
| Characteristic Impedance (NQP Paired Cables) |
Ranges from 150 ohms to 45 ohms, dependent on wire size (AWG), geometry and drive method. Consult our technical staff for data on specific cable types. | |
