It should be common-sense knowledge that liquids flow through large-diameter pipes easier than they do through small-diameter pipes if you would like a practical illustration, try drinking a liquid through straws of different diameters. The same general principle holds for the flow of electrons through conductors : the broader the cross-sectional area thickness of the conductor, the more room for electrons to flow, and consequently, the easier it is for flow to occur less resistance. Electrical wire is usually round in cross-section although there are some unique exceptions to this rule , and comes in two basic varieties: solid and stranded.

Skin effect

The shape and dimension of the wire used in a coil winding are designed to fulfill a specific purpose. Efficient coils minimize the materials and volume required for a given purpose. Since round wires will always have some gap, and wires also have some space required for insulation between turns and between layers, the fill factor is always smaller than one. To achieve higher fill factors, rectangular, square or flat wire can be used. MWS skilled technicians produce the highest-quality magnet wire used in custom windings.

In sliding mechanics, archwires should slide easily during the retraction of anteriors. Round wires slide well, but the torque control is a significant problem. Rectangular wires produce effective torque expression but pose a challenge to free sliding due to factors like friction and force used to overcome friction, etc. To utilize the properties of both wires, the wire should be bi-dimensional. Dual-dimensional wire is one such wire with different dimensions in the anterior and posterior sections. This study aimed to compare the amount of space closure and anchorage loss of molars between the rectangular and dual-dimensional wire groups during retraction with mini-implants.

Low-Field MR Coils: Comparison between Strip and Wire Conductors

In electrical engineering , coil winding is the manufacture of electromagnetic coils. Coils are used as components of circuits, and to provide the magnetic field of motors, transformers, and generators, and in the manufacture of loudspeakers and microphones. The shape and dimensions of a winding are designed to fulfill the particular purpose. Parameters such as inductance , Q factor , insulation strength, and strength of the desired magnetic field greatly influence the design of coil windings. Coil winding can be structured into several groups regarding the type and geometry of the wound coil. Mass production of electromagnetic coils relies on automated machinery. Efficient coils minimise the materials and volume required for a given purpose.

Skin effect is the tendency of an alternating electric current AC to become distributed within a conductor such that the current density is largest near the surface of the conductor and decreases exponentially with greater depths in the conductor. The electric current flows mainly at the "skin" of the conductor, between the outer surface and a level called the skin depth. Skin depth depends on the frequency of the alternating current; as frequency increases, current flow moves to the surface, resulting in less skin depth. Skin effect reduces the effective cross-section of the conductor and thus increases its effective resistance. Skin effect is caused by opposing eddy currents induced by the changing magnetic field resulting from the alternating current.

Cicoil Flat Cable vs The Challengers

View as PDF. Electrocube designs and manufactures transformers and inductors using aluminum or copper foil in place of the standard copper wire traditionally used for coil windings. As the result of a company-funded development and testing program, Electrocube introduced this unique construction technology, providing practical and economical aluminum foil-wound transformers in the 25 VA through 50 KVA power range. For over thirty-five years, these foil transformers have been used in commercial and military applications exhibiting exceptional reliability and efficiency. The use of aluminum or copper foils results in a transformer with many advantages over conventional wire-wound versions:.

Conductors run in parallel, remaining in the same plane. The result is a nominal life expectancy of more than 10,, flex cycles. Flat Cables also excel in high-density applications, and provide more efficient cable management. Repetitive Flex Failure: The geometry of round profile cable presents enough difference between the outside and inside radii of a bend to produce both flex stress on the jacket and compression on the individual conductors inside. Round cables add another design and manufacturing task: cable management.


done by comparing the results that they provide with experimental data and finite element method (FEM) μ0 the free space permeability. Round solid conductors are widely applied in many applications including bus where the proximity effect factor yp for two-core cables or for two single-core cables is calculated as.
