| Conductors: |
Seven strand, concentric, Class B bare or tinned copper
|
| |
Solid thermocouple extension alloy conductors per ANSI MC 96.1 |
| Insulation: |
105°C (221°F) UL rated PVC. Minimum average insulation thickness for #20, 18 and 16 AWG (0.519, 0.823 and 1.31 mm²) is 0.381 mm (0.015 in) |
| Conductor Assembly: |
Two or three insulated conductors are twisted together to form a pair or triad. Individually shielded pairs and triads have a finished lay of 51 mm (2 in). Unshielded pairs and triads have staggered lays to reduce electromagnetic interference and cross talk |
| Shielding: |
Pairs and triads are shielded with 100% coverage aluminum/ polyester tape and includes a tinned copper drain wire. Shield tape is of a type to provide total shield isolation from all other shields. Cabled pairs and triads are overall shielded with 100% coverage aluminum/polyester tape including #20 AWG (0.519 mm²), seven strand tinned copper drain wire. Overall shielded designs with copper tape or braided tinned copper are also available. |
| Conductor Identification: |
Instrument pairs are black, white and number coded. Triads are black, white, red and number coded |
| Thermocouple pairs are colour coded per ANSI MC 96.1 and number coded |
Colour coded conductors and extruded stripes are available upon request |
| Jacket: |
90°C (194°F) UL rated FR PVC, footage sequentially printed |
Standard colours are black, intrinsically safe blue, or, for thermocouple extension cables, the ANSI colour corresponding to the thermocouple extension alloy type contained in the construction. Additional colours are available upon request |
| Optional Armour and Jacket: |
Optional galvanized steel or aluminum interlocked armour may be supplied. The armour is covered with the same FR PVC jacket as with the inner jacket. |
Two additional armours are available: |
| • |
Galvanized steel served wire armour recommended for vertical riser applications |
| • |
Zetabon® hermetically sealed aluminum barrier recommended for direct burial applications |
Shawflex FR 210 jacket material meets the ICEA 210,000 BTU Flame Test |
