Infantron Wire & Cable - Enameled Magnet Wire

Established in 1996, Infantron Singapore is a leading manufacturer and distributor of magnetic products. At Infantron, we supply all types of magnet wire for your electromagnetic requirements, including motors, transformers, control devices, relays, generators and solenoids. The attainment of the internationally recognized and prestigious ISO 9001:2008 certification mark our relentless pursue of business excellence. Our main products are also UL certified and RoHS compliant.

Enameled wire is a wire coated with a thin layer of insulation to prevent the wire surfaces from being in a short circuit when wound into coils. Magnetic flux is created when current flows through the coil. It is used mainly in the construction of motors, electromagnets, transformers and inductors. For ease of manufacturing inductive components like transformers and inductors, most of these wires can be soldered.

Enameled wires are classified by their diameter (AWG gauge number or millimetres), temperature class and insulation thickness. A thicker insulation layer results in a higher breakdown voltage (BDV). Common temperature classes are 130, 155, 180 and 200 °C.

Enameled Aluminum Wire

The mechanical, electrical and chemical characteristics of aluminum magnet wire differ from those of copper magnet wire because of the inherent differences in the conductor materials. These differences are reflected in certain test procedures and/or performance requirements for aluminum magnet wire, such as elongation, adherence and flexibility, heat shock, scrape resistance, continuity and thermal endurance.

Large round sizes, all rectangular film coated and all fibrous covered wire shall have yield strength not less than 9000 PSI.

Litz wire is constructed from a bundle of individual enameled wire. The individual magnet wire are bunched or braided in twist per length to form the overall construction with the required strands of magnet wire. The design of Litz Wire’s multi-strand construction allows the conductor to minimize power loss due to “skin effect”. Skin effect refers to the tendency of current flow in a conductor to be confined to a layer in the conductor close to its outer surface which occurs at high frequencies. At low frequencies, skin effect is negligible, and current is distributed uniformly across the conductor. However, as the frequency increases, the depth to which the current flow can penetrate is reduced. Litz wire construction counteract this effect by increasing the amount of surface area without significantly increasing the size of the conductor. Litz Wire’s increased surface area without increasing the size of the conductor minimizes skin effect.

Infantron Wire & Cable manufactures a wide range of high quality Litz wire from 0.03mm x 10 to 8,000 strands to 0.10mm x 16,500 strands with 2 layers of kapton wrapping. In order to cater the high demand of our customers, Infantron is also manufacturing rectangular Litz wire based on customer's requirement. The wide variety of Litz wire covering includes Nylon served, Kapton wrapped, Nomex covering, Teflon extrusion, Silk, Mylar, PVC and Dacron etc.

Infantron’s experience R&D engineering team is also capable of designing the Litz wire based on customer's requirement and specifications. Infantron Litz Wire can be used in various application fields to maximise efficiency such as wireless power systems and charges, High Frequency Transformers, High Frequency Inductor, High Frequency Chokes, Electronic Ballast, UPS, Deflection Yokes, Hearing Aids, Power Supply Units and Coils.

The benefits of using Litz are -   Increased efficiency   Mitigation of skin and proximity effect   Minimum eddy current losses   Lowered operating temperatures   Reduced footprint of final product   Substantial weight reduction   Avoidance of "hot spots"
