When dealing with power and control systems in industrial environments, choosing the right cable type is essential for safety, performance, and durability. One type that stands out for rugged applications is the DEF cable<\/strong> \u2014 commonly used in defense, energy, and heavy industry.<\/p>\n \\n<\/p>\n In this guide, we\u2019ll explore everything you need to know about DEF cable<\/strong>, including what it is, its construction, typical applications, and how it compares to other armored cables.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n DEF cable<\/strong> refers to a family of heavy-duty armoured cables<\/strong> originally designed for military and defense<\/strong> use, but now widely adopted across various sectors due to their durability and resilience.<\/p>\n \\n\\n<\/p>\n \\n<\/p>\n Steel wire armouring<\/strong> (SWA) or tape armouring<\/strong> for mechanical protection<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Often copper conductors<\/strong> with PVC or XLPE insulation<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n High resistance to moisture<\/strong>, chemicals<\/strong>, and mechanical damage<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Suitable for direct burial<\/strong>, external<\/strong>, and underground<\/strong> installations<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n In many regions, \u201cDEF\u201d is shorthand for Defense Standard<\/strong> cables \u2014 particularly those built to the UK Ministry of Defence specs like DEF STAN 61-12 (formerly BS G).<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n A standard DEF cable<\/strong> typically includes:<\/p>\n \\n\\n<\/p>\n Conductors<\/strong>: Tinned or plain copper (single or multi-core)<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Insulation<\/strong>: PVC, XLPE, or rubber, depending on voltage and flexibility needs<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Armour<\/strong>: Galvanized steel wires or tape for strength<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Sheath<\/strong>: Outer PVC or LSZH jacket for environmental protection<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n Variants include low smoke zero halogen (LSZH)<\/strong> DEF cables, ideal for enclosed spaces where fire safety is crucial.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n Here are some common types you may come across:<\/p>\n \\n\\n<\/p>\n DEF STAN 61-12 Part 4<\/strong> \u2013 Power and control cables up to 600\/1000V<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n DEF STAN 61-12 Part 5<\/strong> \u2013 Equipment wire and flexible cables<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n DEF STAN 61-12 Part 18<\/strong> \u2013 Multicore screened cables for signal\/data use<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n Each part of the standard refers to a different application or construction type, and they may include variations in conductor class, shielding, or sheath type.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n Thanks to their robust build, DEF type cables<\/strong> are used in:<\/p>\n \\n\\n<\/p>\n Military vehicles and naval systems<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Oil and gas facilities<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Power stations and substations<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Rail and transport infrastructure<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Harsh industrial environments<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n Their shock resistance<\/strong>, UV resistance<\/strong>, and mechanical strength<\/strong> make them ideal for use where standard PVC cables<\/strong> may degrade quickly.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n Although both DEF and SWA cables<\/strong> are armoured, DEF cables are typically designed for higher reliability in critical systems<\/strong>, and may adhere to stricter standards like DEF STAN.<\/p>\n \\n\\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/thead>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/tbody>\n \\n<\/table>\n \\n<\/p>\n \\n<\/p><\/div>\n \\n<\/p><\/div>\n \\n<\/p><\/div>\n \\n\\n<\/p>\n \\n<\/p>\n DEF cables are available in a wide range of core sizes<\/strong>, configurations<\/strong>, and voltage ratings<\/strong>, including:<\/p>\n \\n\\n<\/p>\n Low voltage (up to 1kV)<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Multicore (e.g. 7, 12, 24 cores)<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Custom shielding or braiding for EMI protection<\/strong><\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n Be sure to match the current-carrying capacity<\/strong> and insulation class<\/strong> to your system\u2019s requirements. For exact specs, consult the manufacturer’s datasheet or speak with a distributor.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n At TOT Wire & Cable<\/strong>, we supply a full range of DEF standard cables<\/strong>, with competitive pricing and fast delivery. Whether you need DEF STAN 61-12 compliant cables<\/strong> or other rugged industrial cables, we can provide the right solution.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n DEF cable<\/strong> is a durable, military-grade cable option suitable for demanding environments.
