The specific tool used to strip the outer jacket from UTP (Unshielded Twisted Pair) cable is typically called a UTP/STP Cable Stripper or a network cable stripper. For a heavier-duty option, technicians also use rotary cable strippers.
Wire stripper. A wire stripper is a small, hand-held device used to strip the electrical insulation from electric wires.
The most effective and safest tool to use to strip insulation from electrical wire is a set of wire strippers. They are designed with specialized, graduated notches to remove insulation cleanly without nicking or damaging the metal conductor, offering superior precision and safety compared to knives or cutters.
To strip insulation from very fine wire (like 28-32 AWG), use specialized micro-wire strippers, or soften standard PVC/Teflon coatings with heat to easily pinch and slide the jacket off. For enameled magnet wire, use sandpaper or a chemical stripper.
To remove wire insulation without using cutting blades directly on the metal conductor, you can use heat, friction, or household tools. These methods rely on stretching or melting the plastic jacket so it pulls or pinches right off.
Classic insulation stripper (manual stripper) – this is a simple tool used to remove insulation coating from electrical wires. It usually takes the form of pliers equipped with appropriately shaped holes or blades adapted to different cable diameters.
Yes, it is generally illegal to burn insulation off copper wire in most locations. Open burning of plastic-coated wire releases toxic, cancer-causing fumes, pollutes the environment, and violates clean air regulations. Violators can face severe penalties, including fines up to $25,000 and jail time, according to federal EPA regulations.
The primary technique used with UTP (Unshielded Twisted Pair) cable to reduce signal interference, electromagnetic interference (EMI), and crosstalk is twisting the wires together into pairs. By twisting the pairs in a helix pattern, the magnetic fields of each wire cancel each other out, enhancing signal integrity.
UTP cable is a 100 ohm copper cable that consists of 2 to 1800 unshielded twisted pairs surrounded by an outer jacket. They have no metallic shield. This makes the cable small in diameter but unprotected against electrical interference. The twist helps to improve its immunity to electrical noise and EMI.

Wire stripper
Stripping pliers are used when the insulating protective layer needs to be removed from the wire ends so that they are electrically conductive.
The Megger is the instrument uses for measuring the resistance of the insulation. It works on the principle of comparison, i.e., the resistance of the insulation is compared with the known value of resistance.
To use a cable stripping tool, match the wire to the correct gauge notch on the tool. Clamp down on the cable, give it a slight twist if necessary, and pull straight off. Avoid rocking the tool aggressively, as this can nick the wire.
A wire stripper is a small hand-held tool that is used to remove the insulation from electric wires. These portable hand-held tools are extremely popular among electricians and even DIYers for removing the insulation to replace or repair the wire.
The right "insulation removal tool" depends heavily on whether you are removing blown-in attic insulation or stripping the protective outer jacket off electrical wires. For large-scale building projects, specialized vacuums are used, whereas handheld knives or strippers are used for cabling.
A wire stripper is a hand tool used to remove the protective coating or insulation from electrical wires, enabling the user to expose the wire for connection or repair.
Electricians keep one hand in their pocket—a practice known as the "One-Hand Rule"—to prevent electric current from traveling across their chest and through their heart.
The easiest way to strip wire is using a dedicated set of wire strippers. Simply insert the wire into the slot that matches your wire’s gauge, clamp the tool closed, twist it gently to score the insulation, and pull straight off.
5 Common Mistakes When Using a Wire Stripper
The oldest way is to drill wire sized hole in a 2x4 and screw down a screw perpendicularly so the tip of the screw pokes into the hole from above then pull the wire through the hole. Use a knife to get the outer sheath off. Separate the bare ground wires from the insulated conductors.
The most effective way to remove old insulation depends on the type. For loose-fill insulation, rent a high-powered insulation vacuum to suction it into large, disposable collection bags. For fiberglass batts, roll the strips up manually and place them directly into heavy-duty construction trash bags.
Incorrect Stripping Tools: Using the wrong stripping tool or a tool that is not properly maintained can lead to damage. Heat Damage: Excessive heat generated during stripping can weaken the wire and cause it to fail. Chemical Damage: Exposure to certain chemicals can corrode the wire or degrade its insulation.
