Conductor: Often made from stranded copper or aluminum, sometimes with special coatings (e.g., silver-plated copper or high-strength alloys) for enhanced flexibility and durability┬а37.
Insulation: Materials like┬аFluorinated Ethylene Propylene (FEP), Cross-Linked Polyethylene (XLPE), or ethylene propylene rubber (EPR) are common. FEP offers excellent chemical resistance and maintains flexibility across a wide temperature range (-65┬░C to 200┬░C)┬а37.
Armor:┬аInterlocking aluminum or stainless steel armor┬аprovides mechanical protection while allowing flexibility. Some designs use spiral-wrapped armor for crush resistance and ease of bending┬а12. For extreme environments, double-layer armor or unique non-Newtonian fluid-filled cavities may be used for impact resistance┬а56.
Sheath: Outer jackets are often made of┬аpolyurethane,┬аLow Smoke Zero Halogen (LSZH), or other materials resistant to abrasion, chemicals, and flames┬а48.
Military Specifications: Some cables meet┬аMIL-PRF-46291┬аor┬аMIL-PRF-85045┬аstandards, ensuring suitability for harsh military and aerospace environments┬а8.
Industry Standards: Compliance with┬аTelcordia GR-20,┬аICEA 640, and┬аUL-1666┬а(for riser applications) is common┬а15.
Flame Ratings: Many cables feature┬аriser (OFCR)┬аor┬аplenum┬аratings for fire safety┬а1.
Temperature Range: Typically┬а-45┬░C to 200┬░C, depending on materials. For example, FEP-insulated cables operate from -65┬░C to 200┬░C┬а378.
Bending Radius: Generally┬а8тАУ12 times the cable diameter┬аfor installation and┬а5тАУ7 times for operation, ensuring flexibility without damage┬а1.
