Allied Encyclopedia: All About M5086 Cable

Monday, February 10, 2014

  Allied EncyclopediaM5086 cable is a mil spec wire commonly used in aerospace and aircraft applications because of its strong resistance to impact, abrasion and industrial fluids. Initially known as MIL-W-5086, the standard is actually now managed by the Society of Automotive Engineers, under the specification SAE-AS50861. The cables, however, are still usually referred to by the military spec.

There are seven styles of M5086 aircraft cable, but the two most common for airframe wiring are Type I and Type II: M5086 Type I is typically an unshielded wire constructed with a soft annealed stranded tinned copper conductor, polyvinyl chloride (PVC) insulation and clear nylon outer jacket. It is rated up to 105°C. M5086 Type II cable features two different constructions, determined by gauge size. Sizes 22 AWG through 12 AWG are generally constructed with stranded tinned copper conductors, PVC insulation, white glass yarn braids and clear nylon jacketing. From 10 AWG to 4/0 AWG, M5086 Type II cables are made similarly, but with a flame retardant nylon lacquered glass and yarn braid overall. Type II is also rated from -55°C to 105°C. Both MIL-W-5086 Type I and Type II are resistant to water, fuels, oils, hydraulic fluids, skydrol, dilute acids, ethyleneglycol, alkalis, alcohol and fungus. They are reliable options in applications where cables are exposed to chemical abuse, abrasion and high impact loads. The lightweight walls reduce the overall weight of the cabling, a valuable characteristic in aircraft applications where every ounce counts. The drawback to these two M5086 styles is also one of their strengths. The PVC/nylon constructions offer exceptional resistance to chafing and chemical damage, but they are also more flammable. Because they release smoke and toxic gases when burned, these mil spec wire styles should be used only in unmanned aerospace applications. The other styles of the M5086 specification are less common, but have similar constructions. Varying materials and thicknesses offer different qualities and temperature ranges, lending themselves to different applications. M5086 Type IV, for example, has a tin plated copper conductor and is rated up to 3000 volts. Both Type V and Type VI feature polyvinylidene fluoride jacketing, making them ideal for applications which demand excellent chemical and weather resistance.
