Copper Magnet Wire Manufacturing Process

The enameled wire manufacturer takes you to understand the high-temperature paint wrap of high-temperature paint wires, and it is necessary to judge, whether its appearance, size, and performance meet the technical standards of the product and user technical agreements. After the measurement, test, the technical standards of the product and the technical agreement of the product are compared to the requirements for qualified products, which does not meet the requirements for unqualified products.

High Temperature Aluminum Magnet Wire (Anodized aluminium wire) belongs to the special electromagnetic wire and the insulation layer is the aluminum oxide . Because of no thermal aging phenomenon, it can be used as insulation level of class 220.
The insulation layer of such product is thin, high temperature resistance and insulation performance stability,which is the best choice for low voltage winding wires with producing high temperature, poor environment, heat dissipation difficulty and so on.
It can widely be used in electromagnetic industries at home and abroad.

Glass-fiber covered aluminum magnet wire used to have weak coating strength (abrasion resistance, shock resistance, and flexibility). However, that disadvantage has been significantly improved recently by refining material selection and manufacturing methods. The demand for glass-fiber covered aluminum magnet wire is increasing as the wires have excellent uniformity and electrical properties under high temperatures and humidity.

Flat enameled wire is a type of enameled wire. It is a winding wire made of oxygen-free copper rods or electrical aluminum rods that are drawn, extruded or rolled by a certain specification die, and then coated with insulating paint for many times. The thickness is from 0.025mm To 2mm, the width is generally less than 5mm, and its aspect ratio ranges from 2:1 to 50:1. Flat enameled wire has a wide range of uses, especially in the windings of various electrical equipment such as telecommunication equipment, transformers, motors and generators.

According to SMM survey data, the operating rate of enameled wire in September was 71.32%, down 8.28% year-on-year, down 1.82% month-on-month, and 1.65% lower than the expected 72.97%. Among them, the operating rate of large enterprises was 71.56%, down 0.69% from the previous month; medium-sized enterprises fell by 4.06% to 71.50%, and small enterprises fell by 0.55% to 60.83%.

Telephone cable is usually thought of only as a communication medium operating at a normal 48 Vdc level. But telephone cable is regularly used by telephone operating companies to supply power to remote telephony equipment such as: PCM (Pulse Code Modulation) repeaters, FDM (Frequency Division Modulation) repeaters, telegraph and various types of control circuits. The normal talk battery voltage is regularly exceeded in the case of long subscriber loops utilizing loop extenders and on dial long line circuits which operate in the 70 to 100 Vdc range. For these applications, the referenced devices are generally current limited to approximately 150 milliamps. In all such cases, normal telephone industry practice usually limits pair-toground applied voltage to 150 Vdc, and pair-to-pair voltage is usually limited to 300 Vdc.

Compared with general round wires, flat enameled wires have the following advantages:
Higher floor area ratio and better use of space: The high conductor density enables coils and components of the same size to achieve higher efficiency, save materials and reduce costs.

Three-layer insulated wire structure
High-frequency transformer triple-insulated wire is a high-performance insulated wire, so as the name suggests, this wire has three insulation layers with a core wire in the middle.

UL Certificated 220 High Thermal Class Oxidized Film Aluminum Wire and aluminum strip insulated with aluminum oxide film are used in the fields of electronics, missiles, nuclear reactors, aerospace and aircraft industries. The oxide film has high flexibility and is suitable for winding electromagnetic coils of various shapes and sizes. The use of round or rectangular aluminum wires and aluminum strips can save 50% of metal, so it has commercial value. For example, linear motors and medical equipment industries are widely used because of their light weight and low inertia. For rotating equipment, light weight can simplify the dynamic balance, thus reducing the vibration generated by the dynamic balance, thereby improving the sensitivity of the moving coil and its high-frequency response.
