and is suitable for use in Class I and Class II, Division 2, Hazardous Locations
Design Standards
| Bare Conductors: |
Solid and seven strand bare or tinned copper conductors #18 - 8 AWG (0.823 - 8.35 mm²). The cable is available
in 2 to 50 multi conductors or 1 to 50 pairs and triads depending on gauge size. Other stranding is available upon request. |
| Insulated Conductors: |
NEC Type XHHW-2 rated flame retardant cross-linked polyethylene (FR XLPE) is suitable for use in wet or dry locations
at operating temperatures of up to 90°C (194°F), in accordance with UL 44. VW-1 rated conductors are available upon request. |
| NEC Types THHN and THWN PVC insulated and Nylon jacketed, are suitable for dry location at operating temperatures
of up to 90°C (194°F) or in wet locations at operating temperatures of up to 75°C (167°F) in accordance with UL 62 and 83. |
| Insulation Colour Code: |
Singles: black and number coded
Pairs: black and white, and number coded
Triads: black, white and red, and number coded
Other colour codes are availably upon request. |
| Grounding Conductor: |
Bare copper or insulated grounding conductors sized per UL 1569 for use in multi conductors cables. |
| Fillers: |
Non-hygroscopic filler materials are used where necessary to ensure cable roundness. |
| Shielding Options: |
The cable is available with unshielded, overall shielded or individual and overall shielded pairs and triads.
The shielding material consists of 100% coverage aluminum/polyester tape with a tinned copper drain wire. |
| Copper tape or tinned copper braid shielding is available upon request. |
| Rip Cord: |
A Nylon rip cord is applied under the jacket to facilitate easy removal. |
| Inner Jacket: |
All MC cables are offered with an inner 90°C (194°F) Flame Retardant Low Acid Gas PVC jacket with a minimum
average thickness of 50 mils. |
| Armour: |
Armour consists of interlocked aluminum alloy or steel. Minimum armour thickness is 23 mils for aluminum and
17 mils for steel. |
| Outer Jacket: |
An optional outer 90°C (194°F) Flame Retardant Low Acid Gas PVC jacket may be applied over the cable armour
with a minimum average thickness of 65 mils. Other jacket types are available upon request. |
