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.

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.

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)

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."

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.

We design the cable according to different standard or users requirement.

The normal outer sheath materials are PVC, PE, Rubber, Elastomer compound, and others special material as PPL used in submarine cable, above-mentioned material are compound, we can design them accord to users different requirement, for example flame resistance, fire proof, oil resistance, termite proof, anti-corrosion weather proof and so on.

The normal conductor materials are copper, aluminum, aluminum alloy, copper clad steel, aluminum clad steel, and some metal alloy used in thermocouple cable.

PVC(Polyvinyl chloride) insulated PVC insulated cables are used in power distribution, building wire, appliance wiring, flexible cord and machine tool wiring which voltage is less than 0.6/1kV. Communications application use PVC coverings on a limited basis. Insulation and jacket made from PVC have a number of desireable properties that make them the insulation and jacketing material of choice for many common applications. There properties include flexibility, resistance to temperature, resistance to adverse environmentle situations and low cost.

All welding cables have relatively high strand counts compared to other types of stranded cable. Tano Cable's smallest welding cable, 6 AWG, has 259 individual strands of copper wire. Though there are other benefits, the primary reason for stranding in cables is to increase flexibility, and the higher the strand count the more flexible the cable will be.
