First, it’s purpose:
- Organizes your wires, optimizing space in the process
- Acts as a wire covering, giving protection from moisture, temperature changes, abrasions and if outside, the elements
- As a sleeve for wires, it prevents the wires’ currents from coming into contact with other conductors
What are spiral shield cables used for?
Spiral shields are basically coils of wire exhibiting inductive effects and large high-frequency shield transfer impedances. Therefore, spiral shield cables should not be used in high-frequency applications (such as video), and their use should be limited to low frequency applications (such as audio).

Why does coiling a wire increase current flow?
As the number of coils are increased the magnetic field will become stronger, because each coil has its own magnetic field, so the more coils there are the more field lines there are which means it would be a stronger electromagnet.
Does coiling wire increase resistance?
The simple answer is no. Winding wire on a non-ferrous form will not change its resistance.
What is coiled wire?
Coiled wires (also called retractile cords) are great for keeping long wires tidy and together. Their springy nature allows them to be stretched and then return to their coiled shape, keeping your wire localized and neat looking.
What are spiral cables?
Spiral cables are coiled wires that can be extended for the purpose of connecting different elements. Although they serve the same function as regular cables, spiral cables are still more beneficial. These cables are usually 10-15 feet in length, which provides easy handling in different factories.
What is the purpose of spiral cables?
Spiral cables have roles in a comprehensive range of businesses. From handling different equipment categories to lifting ramps and power tools, spiral cables are required in all spheres.
Final words
To conclude the discussion, it can be said that spiral cables have important roles in factories, machinery, and mechanical fields. Their flexibility, along with the high quality, is the reason why they are becoming so popular compared to traditional cable designs, even in the home for organisation.
Why use a spiral shield on cable?
Normally when a spiral shield is used on a cable it is for one of three reasons, increased flexibility, ease of termination, or reduced manufacturing costs.
What is the effect of spiral wound shield on a cable?
The cable in question, with a spiral wound shield and spiral wound center conductor, will have increased inductance and increased characteristic impedance. It will also have reduced ac resistance and increased high-frequency shield transfer impedance (less shielding effectiveness).
What happens to the transfer impedance of a cable shield when the frequency increases?
As frequency increases the transfer impedance of a solid homogenous cable shield decreases , due to skin effect, and the shielding of the cable increases. Skin effect causes the noise currents to remain on the outside surface of the shield and the signal currents to remain on the inside surface of the shield.
How to determine shielding effectiveness of coaxial cable?
The shielding effectiveness of a coaxial cable can be expressed in terms of the shield transfer impedance [1]. The lower the transfer impedance the more effective the shielding. This means that the signal stays on the inside of the cable and any noise present remains on the outside of the cable, and "never the twain shall meet."
What is the transfer impedance of a spiral shield cable?
For a spiral shield cable, however, the transfer impedance contains two terms, one due to the longitudinal component of the shield current that decreases with frequency (which is good), and the other due to the circular component of the shield current that increases with frequency (which is bad). The net effect is that the shield transfer impedance increases with frequency above about 1 MHz. The high frequency transfer impedance is a strong function of the pitch angle, the larger this angle the larger will be the transfer impedance and the less shielding effectiveness the cable will have.
What is the total current of a shield?
The total current 'I' in the shield can be decomposed into two components. The longitudinal current I(L) along the cable axis is equal to I cos ø, and the circular current I(c) perpendicular to the cable axis and around the circumference of the cable is equal to I sin ø. This is shown in the figure below.
What is the magnetic field of an infinitely long cable?
In the case of an infinitely long cable (an approximation to a long skinny cable) the continuous circular current sheet will produce a longitudinal magnetic field 'H' inside the shield and no magnetic field outside the shield, as shown in the figure below.

How to bend cables more sharply?
KNOW: How you position the wrap around your cables will dictate your bundle’s flexibility. If you increase the space between the spirals, you can bend cables more sharply. On the flip side, the closer together you space the spirals, then the less flexibility you’ll have, but the trade-off is that you’ll get greater abrasion resistance.
Does plastic spiral wrap work?
