Copper Magnet Wire Manufacturing Process

Carbon aluminum wire is an aluminum wire for parts manufacturing of various machines.08 and 08F aluminum wire for rolling thin plates, deep-drawing products, oil drums, high-grade enamel products, less demanding carburizing and cyanide parts, welding rods, etc.

Enameled wire is a main type of winding wire. It consists of a conductor and an insulating layer. After the bare wire is softened by annealing, it is painted and baked many times. However, it is not easy to produce products that not only meet the requirements of the standard, but also meet the requirements of customers. It is affected by the quality of raw materials, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, and thermal properties are four major properties.

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.

Good Quality Paper Covered Flat Aluminum Enameled Copper Wire is made of bare copper wire or bare aluminum wire, or paper-covered wire as the core, wrapped with paper for insulation. According to customer and national standards, the conductor is wrapped with telephone paper, electromagnetic paper, and high-density inter-turn insulation paper. As conductor insulation, it is an ideal material for civilian-made oil-immersed transformers; especially semi-hard insulated copper wires, which can significantly improve the winding resistance. The mechanical properties and short-circuit resistance can be widely used in the winding of large and medium-sized transformers.

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.

The enameled wire paint coats up to 30 layers of copper and aluminum wires to provide electrical insulation and help avoid short circuits in the coil. Such enameled wire paint must also have excellent chemical resistance and high temperature resistance, must have excellent adhesion with copper or aluminum wires, and also have excellent mechanical stability.
In some cases, such as for motors driven by frequency converters, a suitable insulation layer should be able to resist partial discharges that may cause short circuits and malfunctions in the engine.

Nomex covering corresponds to class H insulation is mainly used in the construction of condensers and capacitors. Main application of it is in shielding of cables in high temp. environments (200¡ãC) such as dry type transformers, military and aerospace cables. Nomex covered conductors are more effective in condition where temperature resistance and dielectric strength requirements are high.

1060 Transformer Aluminum Strip Product Description:
060 transformer aluminum belt is a special purpose aluminum belt product produced for transformers. It uses high-purity aluminum substrate and aluminum deep-processed products formed by slitting aluminum coils with an aluminum content of more than 99.60%. The raw material of transformer aluminum strip is high-purity aluminum, which is rolled into thin sheet aluminum coils of different thicknesses and widths by a cold rolling mill, and then longitudinally slitted into aluminum strips of different widths by a slitting machine according to the application. It is an important raw material in industry. The main processing equipment of 1060 transformer aluminum strip is slitting unit, which can be divided into required length and width according to needs. Usually the transformer aluminum strip is slit according to the actual needs of the user, which can reduce waste, reduce processing procedures (without cutting), and save raw material costs.

Electrical wiring to be run in conduit comes in individual strands, encased in insulation to protect the wire and insulate it from other wires and the conduit. Wires come in ither solid or stranded, depending on the wire size. Bare conductors are available for ground wires only. The insulation is made to take on some rather extreme conditions. Heat-, oil-, gasoline- and water-resistant coatings are all available to help your Insulated electric wire survive.

Enameled wire
The insulation of enameled wire is varnish film, which is formed by coating insulating varnish on the conductive wire core and drying it.

Round Enameled Wire is used for transformer coil winding and motor winding, also called electric motor winding wire. And to Measure The Specifications Of Round Enameled Wire is important, include the conductor diameter and insulation diameter.

Wire for winding used in electrical equipment is generally called magnet wire. Simply put, ¡°Magnet wire is used for interchanging electrical energy with magnetic energy¡±.
Magnet wires are broadly divided into enamelled wire (coating insulation), covered conductor wire (fiber/film insulation), other specially formulated wire, and combinations thereof.

Copper Magnet Wire Manufacturing Process includes important three steps – enameling, winding and Inorganic insulated wires. Mainly introduce the method to ensure the quality of copper enameled wire.

The AWG tables are for a single, solid and round conductor. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor. Because there are also small gaps between the strands, a stranded wire will always have a slightly larger overall diameter than a solid wire with the same AWG.

AWG magnet wire is also called enamelled manganin wire which is composed of copper or aluminum conductor with insulation materials, such as PE, EI, UE, etc. The enameled wire have different performance according to chemical performance, heat resistance and others.

The samples for tensile and thermal shock testing were 3 pieces of 254mm enameled wire.

First pull the enameled wire to the required elongation at a rate of 3.7-4.6 m/sec, then wrap the jerked sample around the mandrel, and then put the wrapped sample into the oven at the specified temperature for 30 minutes. It needs to be suspended in the oven. After leaving the oven, inspect the baked samples for cracking or peeling of the paint film. In this test, the diameter of the mandrel is usually 3 times the diameter of the enameled wire.

The specified temperature of the oven is set according to the temperature specified for the enameled wire of this ANSI Type in the NEMA MW1000 standard, which is usually the temperature grade of the enameled wire +20¡ãC.

The coating is a process of forming a uniform coating layer of a coating wire to form a uniform coating layer on a metal conductor. This is related to some physical phenomena and painting methods of liquid.
