Important facts on electrical cables and multi-stranded line


Generally, a wire is a long, thin and flexible piece of metal. Electricity will travel through a wire and when people touch wire which is carrying electricity, they get shocked, so the outside coating of electrical wire is colored in various colors. Most cables are black, but occasionally cables can have an inversely colored layer.

A conductor is a material in which electricity can flow through it. Electrical conductors are created by metals such as copper, aluminum, etc. Such metals are used to make wires. Most of the electrical wires and multi stranded wire are made out of copper because it conducts electricity with high flexibility and little resistance.

In addition to the old cables which have some installations, it will have mixed colors on them. The red is connected to the new brown (life), black is connected to the new blue (neutral) and the green and yellow earth stay the same.

Multi-Stranded Wiring:

  • Such multi-Stranded wiring has a higher cost due to the requirement for more rounds of extrusion and stranding.
  • Multi-strand wiring is very flexible and a little susceptible to cracking and metal fatigue than single-stranded conductors.

It is tougher than a stranded conductor, rigid and less flexible than a stranded conductor. Solid conductors are likely to break if you frequent flexing than stranded conductors. It is more flexible than a normal conductor but less durable.

A metal wire that is made up of many smaller wires gets twisted together. Stranded wire is more flexible than wire with a solid normal core.

Larger wiring sizes are unavailable in solid wires because they are difficult to bend. You can use stranded wire anytime when you can get it, and your terminations are listed for stranded wire.

Solid wire is a little costlier to manufacture than stranded wire. It is used when the wire will remain in the same position and flexibility is not needed. Stranded wire delivers more flexibility than solid wire.

Multi-Strand Wires are PVC protected with single center unsheathed electrical wires with multi-strand copper metals. These wires go as the spine for giving bright & supremacy to households, constructions or houses. Multi-Strand wires are made out of numerous gage cables packaged or covered together to assembly a larger conveyor. Stranded wire is more user-friendly than the strong wire of the same joined cross-sectional territory. Stranded wire a tend to be a higher conduit than the strong wire in light that the individual wires all in all contain a more prominent surface zone.


If you hold the ends of solid and stranded wire with each other while you screw on the wire nut connector, the stranded wire will usually wrap loosely around the solid wires, results in a loose connection. Then install the wire nut connector. Because of the small gaps between the strands in a multi stranded wire, a stranded wire with the same current-carrying capacity and electrical resistance as solid wire, always have a slightly larger overall diameter. The higher the number is thinner the wire than electrical wire.
