The advantage is that it is strong and can stand up to many types of weather. Disadvantage is that it will get rusty easy.
Cables are two or more wires running side by side and bonded and there is armored and unarmored cable. Armored cables are protected by flexible steel covering while the unarmored cable is only covered by plastic.
Because the steel strengthens the cable
A cable joint is where multiple cable join together! Here's an XLPE cable joint(for other types of cable theres an other type of joint example: for a steel cable for bridges theres an iron/steel joint):
pylons are made of steel as it is a strong metal but cables themselves are copper. ps this is a terribe website
Some are: 1. Less Steel used...less cost. 2. Less Weight for a given design strength. 3. Less Weight for a given Length.

whatare advatages and disadvantages of steel
Advantages of steel frames include the fact that they are durable and strong. Disadvantages are that they are heavy and difficult to move. They are also hard to manufacture.

Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Unarmored electrical cable has no protective flexible steel covering, its covering is made of plastic.
Steel tape armoured(STA) is only used for buried cables or ordinary wear tube, common ground, tunnel laying. For the last of the cable package to protect. Steel tape armoured is one kind of armored cable. General use the left double gap around the package, the lapping gap is not greater 50% of the bandwidth. And the inner steel strip gap should be close to the middle part of the outer strip. Steel tape armoured commonly used galvanized steel and painted steel armor, common specifications can be divided according to the thickness: 0.25mm,0.3mm,0.5mm,0.8mm. Galvanized layer should be uniform and complete, no peeling, cracking, corrosion. The coating layer of painted steel strip should be uniform and continuous, allow a slight sagging, bruises, but may not have a large loss or missed.
* Aluminium is lighter and doesn't rust * Steel is cheap, it is very hard, but can break
To test the continuity of steel wire armoured (SWA) cable, a continuity tester or multimeter is used to check for a complete electrical path. The outer steel armor is connected to the earth, while the inner conductors are tested individually to ensure they are properly connected and have no breaks. The resistance should be low, indicating good continuity. Additionally, the test should confirm that there is no short circuit between conductors or between conductors and the armor.
Armoured cable is a type of electrical cable that is protected by a layer of armor, typically made from steel or aluminum, which provides mechanical protection against physical damage. This type of cable is commonly used in environments where it may be exposed to harsh conditions, such as in underground installations or industrial settings. The armor can also enhance the cable's resistance to electrical interference and improve its durability. Armoured cables are often used for power distribution and connections in both residential and commercial applications.
Cable Glands cover the whole spectrum of armoured and non-armoured cable and applications from general industrial through increased safety, deluge, flameproof and explosion proof. The Cable Glands are available in Brass as standard with Stainless Steel, Plastic and Aluminium, as an optional material on certain designs. Generally they are used by oil and gas units, electrical cable sealing companies and marine applications. Depending on the applications they are many type of cable gland available like indoor cable glands, outdoor cable glands and cable gland accessories like PVC shrouds, lock nuts and cable ties.
