FAQ
Q
How to design the cables?
A
We design the cable according to different standard or users requirement.
Q
How to design the cross-sectional area of metal screen in power cable?
A
The cross-sectional area of metal screen in power cable according to the standard requirement, if the standard doesn’t required of this specification, we will design it accord to the user requirement, for example, we have to know the user’s used purpose, the short-current of user’s power system.
Q
What is Flexible Cable?
A
What is Flexible Cable?
Flexible Cable is a cable that possesses flexibility for challenging cable positioning. We defines "flexibility" as "that quality of a cable or cable component which allows for bending under the influence of outside force."

How many types of cable flexing are there?
There are four common types of cable flexing movements. These include rolling flex, bending flex or "tic-toc," torsional flex and variable/random motion flex. Usually flexible cable are some kinds of rubber cable, control cable, instrument cable, welding cable and mine cable etc.

In what types of applications would I use Flexible Cable?
Flexible Cable is utilized in numerous applications to withstand the extreme stress of flexing and motion. A few applications include: drag chain applications, applications with repetitive bending and torsion stress, machine tools, data processing equipment, robotics, assembly lines, automation networking, microprocessor and computer interconnects and many more.

Do Flexible Cables meet industry standards?
Flexible Cable styles meet various approvals. Flexible Cable may be UL Listed, CSA certified, CE marked and/or meet military specifications. However, every flexible cable is different, so make sure to specify if your flexible cable needs one or more standards to be met.
Q
Are instrument cables used for high-impedance or low-impedance lines?
A
Generally, the source impedance is the determining factor in cable selection. Instrument cables are used for a wide range of sources. Many keyboard instruments, mixers, and signal processors have very low (50 to 600ohm) source impedances. On the other hand, typical electric guitar or bass pickups are very inductive, very high impedance (20,000 ohms and above) sources. Typical load impedances are greater than 10,000 ohms, which limits the electrical current flow to a very small amount on the order of a few thousandths of an ampere(milliamps).
Q
How much power does an instrument cable have to carry?
A
The voltages encountered range from a few millivolts, in the case of the electric guitar, to levels over ten volts delivered by line-level sources such as mixers. By Ohm’s Law this represents power levels of less than a thousandth of a watt.
Q
What kind of frequency response does an instrument cable need? What are the lowest and highest frequencies produced by the source?
A
The bandwidth spans the entire audible range of frequencies, from the 41 Hz (and below) of bass guitar and synthesizer to the 20 kHz harmonics of keyboards and cymbals. Recording applications demand wide bandwidth to preserve the “sizzle” of a hot performance. Even an electric guitar has a bandwidth of about 82 Hz to above 5 kHz.
