I just repaired my kncok sensor, its not too hard to repair a shielded wire. Strip the top coating and peel back that wire to get to the small insulation, strip that and solder/splice the small wire, shrink wrap or electrical tape real tight and then do the same for the surrounding wire.
What is the purpose of shielded in a wire?
When deciding on the type/amount of shielding required, consider the following factors:
- Type of signal interference – EMI, RFI, or ESI
- Noise level
- System configuration
- Cable cost – is more shielding necessary?
- Cable diameter, weight, and flexibility

How to shield a wire?
Some of them are:
- Much more flexible than your typical braided cable.
- Has a much wider coverage range than a braided shield which varies from 90%-99%.
- Easier to terminate than braided shields.
- Gives you more control over the EMIs/RMIs.
How to fix coax cable?
Steps
- Hold the cable in one hand (as if it were a stick to be whittled), with the end to be stripped pointed away from your body.
- Hold the razor knife in your dominant hand and extend the blade if not done so already.
- Firmly press the edge of the blade (not the point) into the cable at a right angle (perpendicular to the cable) about an inch from the end.

How do you connect shielded wire?
The best way to wire shielded cables for screening is to ground the shield at both ends of the cable. Traditionally there existed a rule of thumb to ground only the source end of the shield to avoid ground loops. Best practice is to ground at both ends, but there is a possibility of ground loops.
Does shielded wire need to be grounded?
The cable shielding and its termination must provide a low-impedance path to ground. A shielded cable that is not grounded does not work effectively. Any disruptions in the path can raise the impedance and lower the shielding effectiveness. 1.

Can I use aluminum foil to shield wires?
Yes aluminum foil can shield cables. Just wrap it good and tight.
What is the purpose of shielded cable?
Shielded cable acts to reduce volume and intensity of all kinds of electrical noise and EMI, along with the adverse effects it has on signals and transmission. Whether radiated or conducted, EMI can seriously disrupt the proper operation of other equipment.
What is difference between shielded and unshielded cable?
Shielded twisted pair cable (STP) has the individual pairs of wires wrapped in foil, which are then wrapped again for double protection. Unshielded twisted pair cable (UTP) has each pair of wires twisted together. Those wires are then wrapped in tubing without any other protection.
Where do you ground shielded wire?

Which end of a shielded cable should be grounded?
(4) Wikipedia, Shielded Cable: The common method to wire shielded cables is to ground only the source end of the shield to avoid ground loops.
How do you test shielded cable?
The easiest way to test shield integrity is with a DC continuity test. Put a voltage on the cable at the near end, and if it shows up at the far end, it is assumed to be connected properly. While that is true for the conductors in the cable, it's not necessarily true for the shield.
Can aluminum wire be soldered?
Answer: Soldering to aluminum is very difficult and quite different than soldering to copper or solder coated surfaces. The issue with aluminum is the oxide on the aluminum itself and it needs to be removed so the solder can make a electromechanical bond to the shield itself.
How do you solder braided shield?

What is a shield terminator?
SolderSleeve shield terminators provide an environmentally sealed, insulated, and encapsulated solder connection for a variety of applications.
What is solder sleeve?
Solder Sleeves are small, hollow pieces of heat shrinkable tubing that have rings of solder incorporated into them. As they are heated, the tubing shrinks making a mechanical bond between the wires inserted into them. At the same time, the solder melts forming an electrical connection, securely splicing wires together.
how to repair shielded wire
as said,my damn belt grinded through my wiring harness for the alt,o2,ac,water sensor.it somehow chew through two wire and almost through one more.it is effecting my gas mileage bad because one of the wire that it chew through was probably a wire for the o2 sensor that is why it is telling me that my heater circuit is shorted in my o2 sensor.so enough about me telling you guys about it cause one wire was a shielded wire, how do i repair that.ill be using a soldering gun with heat shrink but do i have to solder the shielded part too???.

Re: how to repair shielded wire
If it's like the knock sensor, the shielding grounds to E2 on the ECU side. Do not ground it on the sensor side.
How to fix burned wire in electrical box?
Fix burned wire inside electrical boxes by replacing charred insulation. You can do this quickly and easily without pulling in new wires.
How to remove insulation from 12-2 wire?
Peel off the outer jacket of 12-2 nonmetallic cable. Then strip off about 8 in. of insulation from the black and white wires.
Why is the insulation on my ceiling light cracked?
The usual reason insulation gets ruined is that the bulbs in the fixture exceeded the fixture’s wattage rating. That extra heat literally baked the insulation. Usually the insulation outside of the ceiling box is OK. But you’ll have to repair the damaged insulation inside the box. No, you can’t just wrap the bare wires with electrical tape. That’s not an acceptable long-term fix. Here’s the right way to fix the problem.
How to burn shrinkable tubing?
Wave the flame from a lighter under the heat shrinkable tubing. Keep the flame moving so the heat does all the work and the tubing doesn’t burn.
Can you wrap wires in a ceiling box?
But you’ll have to repair the damaged insulation inside the box. No, you can’t just wrap the bare wires with electrical tape. That’s not an acceptable long-term fix. Here’s the right way to fix the problem.
What is shielded wire?
Electrical cables contain one or more insulated conductors. These are often a conductive layer, a shielded wire, or a Shielded cable surround it. These wires help in securing the safety of electrical wires that run through your house or property. In general, shielded cables can also prevent various electrical disturbances, such as electrical disturbances and noise from various heavy machinery in the workplace.
What if you don't have a cable for shielding?
If you don’t have a cable for sufficient shielding for the application needs, it could be a problem. If there is a noisier environment, we suggest going in for the braid combinations.
What is braided shielding?
This type or form of shielding is the oldest kind of shielding. Manufacturers still practice this format present times. The process of making small gauge wires in a woven pattern defines braided shielding. Braids are usually made up of copper, aluminium, steel, and tinned copper, and weave it on the conductor like a fabric weave. They are most effective and useful for low frequencies and provide flexibility, mechanical strength, and life to the cable.
Why are shielded cables needed in factory?
It is because of unshielded cables that cause this level of interference and is very hazardous for industry workers and laborers. Therefore, installing shielded cables will improve your factory’s working conditions. It will also ensure every worker’s safety.
What is shielding cable?
A shield is generally an electrically conductive substance. It surrounds a wire or cable, which prohibits any signal getaway. The shielding of the cable, in turn, is simply enclosing the inner signals or power-carrying conductors. Shielded cables interact differently with electromagnetic interference (EMI). They can be both a source of EMI as well as a receiver. As a source, cables can radiate signals to other cables and even act as an antenna that radiates noise.
How to stop EMI in office?
Thus, stop any EMI generation on your office floor by installing shielded cables. Shielded cables installed on normal electrical wires can make your workplace better and safe.
How does coax cable work?
Coax cables are very useful and effective. Their shielded designs allow them to transmit data or radio frequencies from one point to another at a much faster rate. It works through a central conductor, generally a copper wire that carries audio and video signals. A dielectric plastic insulator wraps and encloses the copper wire. A braided mesh extracted from copper then shields the cable from EMIs/RMIs.
