1. Reliability
The simplicity of the flat cable and its parallel conductor geometry eliminate many common sources of wiring errors and failures. The registered conductors are one-to-one terminal connectors or boards, making proper contact assignment almost automatic.
2. Weight Reduction
The use of flat cables often eliminates most of the weight of traditional wires. Such as excess insulating materials, fillers and tape are not necessary. In addition, the composite flat cable structure has strong mechanical strength, so there is no need to use large conductors to increase strength. Therefore, the copper cross-section can be reduced to the size that carries the current load or meets the voltage drop requirement.
3. Space Efficiency
Eliminate unnecessary insulation, filler and tape reduce the volume and physical volume of the flat cable. In addition, their low profile allows them to embrace the surface and utilize tightly or normally used spaces. The rectangular cross-section allows flat cables to be stacked or layered, with almost no wasted dead space between the cables, providing the maximum conductor density for a given volume.
4. Flexibility
Flat cable is extremely flexible when bent in the plane of its thin cross-section. This flexibility has been utilized in applications where continuous or high flexing is necessary, e.g. drawers, doors, rotating arms, etc.
5. Greater Strength
Strength is enhanced by the fact that all conductors and insulation equally share tensile loads.
6. Consistent Electrical Characteristics
Since the spacing of the conductors is fixed and the geometry of the cable is constant, its electrical characteristics, such as impedance, capacitance, inductance, delay, crosstalk, and attenuation, are consistent.
7. Greater Current Carrying Capacity
Flat cables have a larger area-to-volume ratio than round cables, and therefore have higher heat dissipation efficiency. This allows a higher current level for a given temperature rise and conductor cross-section.
8. Reduced Skewing Effects
Because conductors have precise physical and electronic lengths, and a continuous and consistent dielectric medium, in a given flat cable, the time delay between signals is minimized.
9. High-Density Interconnections
The cabling density achievable using flat cable is superior to that using conventional cable because of the high wire-to-cable cross-sectional density. Layers of flat cable are more effectively packed for higher conductor density than round cable.
10. Ease of Handling
Flat cable folds and bends readily, conforms to the mounting area, fastens easily with clamps, adhesive, or double-faced tape, and eliminated the installation and lacing difficulties associated with round wire cabling. Visible conductor in a fixed position within the dielectric simplify coding , inspection and circuit tracing.
