Định Nghĩa và Ý Nghĩa của "armored cable"

What is "armored cable"?

Armored cable is a type of electrical cable designed with a protective metal layer, often made of steel or aluminum, around the insulated wires inside. This metal shielding provides extra durability and protection against physical damage, such as impacts, cuts, or exposure to harsh environmental conditions. Armored cables are commonly used in construction or industrial settings where the wiring may be exposed to heavy machinery or outdoor elements. They are also used in areas requiring additional safety, such as underground installations or in places where fire resistance is important.
