How To Fix A Frayed Wire? Here’s How To Fix Broken Charging Cable?

Do you have a micro USB cable or headphones which is broken? Have you ever thought about how to fix a frayed wire on a smartphone? 

Almost everyone I know has an out-of-date charging cable for their phone or tablet.

Maybe it has a nick from being run over by their office chair, or maybe it just has awkward knots and bulges from months of daily use.

In any case, you really shouldn’t be using that cable — you never know when the damage will progress far enough to give you a shock, zap your phone, or even start a fire, which happens all the time in the UK and around the world.

Here’s our comprehensive cable safety guide, divided into three sections: when to replace a cable, how to repair damaged cables, and how to prevent cables from becoming damaged in the first place.

A frayed charger is not only inconvenient, but it can also be dangerous. In this Instructable, I will demonstrate three methods for repairing or protecting a broken charger. Let’s get this party started!

When electrical cables are moved and bent frequently, the outer jacket can rip and expose the electrical wires inside.

This is especially common in cables that are frequently used, such as phone and laptop chargers.

If you notice exposed wires in your electrical cables, fix them as soon as possible to prevent the problem from worsening.

Repair minor electrical cable damage with electrical tape, repair damaged charger cables with Sugru putty, or repair more serious electrical cable damage with heat-shrink tubing.

If you have an extremely worn out cable with exposed electrical wires due to new tears in the outer jacket, it’s probably best to replace it.

What is a Frayed Wire?

A frayed wire is one with its ends severed or exposed through its insulation. Frayed wires can reduce performance and even be dangerous if left in disrepair.

What should you do if you find a frayed wire, and can it be repaired? In this overview, our experts go over our top frayed wire fixes and recommendations.

When wirings get damaged

Frayed cables and wires are not only an annoyance and an eyesore; they are also a potential electrical disaster. Homeowners must be vigilant in addressing these electrical issues in order to avoid injury or accident. Electricians’ Union published an article on how to deal with frayed wires. “This is a very dangerous condition that can lead to short circuits and a fire hazard.” Normally, 2 or 3 wraps of electrical tape around the damaged area should suffice. However, if the insulation is old and brittle, it will come apart and become worse as you try to wrap the old wire and insulation with electrical tape. Fortunately, this is a relatively simple fix that can be accomplished with “Heat Shrink Tubing,” as I’ll explain in the next step.”

Dealing with Frayed Electrical Wires

“This splice repair technique is useful for repairing damage when the electrical cable does not have enough slack to rejoin the ends together with wire nuts in a single junction box.”

For example, if a squirrel or rodent chewed through an electrical cable in the attic, or if, as in my case, I needed to reroute the wire to correct a building code violation.”

What to Do With a Frayed Wire?

Frayed wires can be caused by a number of factors, including:

  • Rodents gnawing at insulation
  • Scraping wires against a sharp metal surface
  • Excessive bending or movement around a specific area of the wire, particularly the ends

When the metallic innards of a wire are exposed, it can pose a risk to both the system to which it is connected and the surrounding environment. Wires are insulated to prevent current from coming into contact with another potential conductor, which can be disastrous.

When there is too much electricity or power in a cable system, electronics, appliances, or any other type of machinery can overpower and short circuit, frying the electrical components.

Worse, as the current flows freely, some frayed wires may start fires.

What should you do if you find a frayed wire? Metal poking through a wire’s insulation requires immediate attention.

You can either replace the wire completely or, depending on the severity of the fraying, you may be able to fix the problem with some simple frayed wire fixes.
