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.

Copper paint package wire production process principle

Copper lacquer wires are coated with respective lacquer solutions, and then cured by solvent volatilization and paint film.The earliest enamel wire is oily painted wire, made from tung oil.Its paint film is abrasion resistant, and cannot be used directly to make motor coils and windings, and the cotton yarn can be added to the layer.Later, polyethylene glycol formaldehyde lacquer wire came out, and its mechanical properties were greatly improved, which can be used directly for motor windings, which is called high-strength enameled wire.

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.

The enameled wire has always been a very important industry in the national economy, and with the continuous change and development of the market, the enameled wire industry is constantly adjusting, from the current perspective, the future of the entire enamel wire industry will move towards the future.

Oxidative Aluminum 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.

The enamel wire is a major variety of winding wires, composed of two conductors and insulating layers, after the naked wire is deck, and then painted, baked.However, it is not easy to produce products that meet the standard requirements, but also meet customer requirements, it is affected by factors such as raw materials, process parameters, production equipment, environment, and therefore, the quality characteristics of various enameled wires are different, but they haveFour major properties of mechanical properties, chemical properties, electrical properties, and thermal performance.

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.

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.

Round Enameled Wire can be designed in 0.016-7mm, why choose the round enameled wire used for your electrical equipment and other electric field. List the 4 characteristics of enameled copper wire.

Nomex Paper Covered Copper Aluminium Enameled Wire is a kind of electromagnetic wire, which is specially used to manufacture winding coils of various oil-immersed transformers. It has good insulation on the outside and good conductivity on the inside. It is the heart of the transformer.

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.

The infrared spectrum analysis test is based on the standard UL746A, which only confirms the chemical composition of the paint film, establishes the infrared spectrum and retains it. After the enameled wire is certified, samples will be sampled for testing every year during the follow-up inspection service. The infrared spectrum made by the paint film on the sampled sample needs to be compared with the infrared spectrum established on the sample at the time of certification. The two infrared spectrums must be comparable. superior.

¡ñ Conductor resistance. Measure with a conductor resistance tester, and then change to the value at 20¡ãC for comparison.
¡ñInsulation destruction voltage. Twist two enameled wires, apply voltage between the conductors, and judge by the damage voltage of the paint film. This performance is analyzed and judged through two tests of normal state and cold state breakdown voltage.
¡ñPaint film continuity (pinhole). Check the small holes of the paint film with a certain length of the test material. The project is tested by a high-pressure paint film continuity tester.

The current enamel wire industry is relatively low due to the admission threshold, and therefore the production enterprises have more and more, and the market competition is constantly intensified, but in the high-end product field, there are not many companies that can enter, in the present, and future, The enamel wire business wants to achieve better development, and build brands and scale becomes more and more important.

Although the quality of enameled wire depends to a large extent on the quality of raw materials such as paint and wires and the objective conditions of machinery and equipment, if you do not take a series of problems such as baking, annealing, and speed, and understand their interrelationships. , Do not master the operation technology, do not seriously do the touring work, stop and tidy up the work, do not do well in the process and hygiene, even if the objective conditions are good, it will not be able to produce high-quality enameled wire. Therefore, the decisive factor for good enameled wire is people’s sense of responsibility for work.
