As the basic conductor of other winding wires, bare copper wire is defined as an oxygen-free copper rod that is made into various specifications of flat wire or round wire after a specific specification mold extrusion or drawing is made in accordance with customer requirements. This wire is then prepared for coating processes using paint, paper, fiber glass, or other insulating material covering insulation. The product can be used for life wire supplies or winding of transformers, generators, motors, reactors, and other electrical equipment.

Polyester/Polyimide film covered winding wire is made by copper or aluminum conductor. At first wrapped polyimide film which is coated with adhesive material on the conductor, and sintered film and film,to make it with conductor together. After heating, the fluorine on the composite film is melted, so that the film and the conductor are bonded as a whole. This product has excellent voltage resistance, thin insulation thickness and heat resistance up to 220 ºC. It is mainly used for winding of motors, reactors, welding machines or other similar electrical products. The electrical bare copper (aluminum) wire produced by extrusion process is an ideal material for producing polyimide film clad wire.

Fiberglass covered Aluminum/Copper wire is according to customers requirement, Aluminum/Copper conductor is evenly covered with one or two layers of non-alkali fiberglass, then it's impregnated in compatible insulating coating of required thermal class baked to make a whole between fiberglass and Aluminum/Copper conductor (optionally be applied to polyester and polyamide).

 Paper-Coated Magnet by NOMEX After being drawn or extruded from electrical round aluminum rod or oxygen-free copper rod using a particular mold, wire is wrapped in NOMEX paper of Type T410 from the US Du Pont Company. Transformers, electric welding machines, and other such electrical devices use it extensively. The best material for NOMEX paper wrapped wire is electrical bare copper or aluminum wire that has undergone an extrusion process.

Enameled square wires are characterized as an oxygen-free copper rods that have been baked to meet temperature resistance index specifications, work with insulating paint, and suit customer needs. Following that, a variety of complementary insulating paints can be used to paint these wires. Mold or felt paint can be used to achieve these goals. These magnet wires can be used to wind transformers, generators, motors, reactors, and other electrical equipment.

Enameled square wire is a main type of winding wire. It consists of two parts: the conductor and the insulating layer. The bare wire is annealed and softened, and then baked and baked. However, it is not easy to produce a product that meets both the standard requirements and the customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have four properties of mechanical properties, chemical properties, electrical properties, and thermal properties.

Enamelled aluminum wire is a type of winding wire made by electric round aluminum rod which drawn by dies with special size, then over coated with enamel repetitiously.Enamelled Round Aluminum Wire is a fundamental part of a winding in every electrical machine or apparatus. Compared to fibrous insulations, enamelled aluminium wire offers a favourable space saving factor together with a high level of breakdown voltage. The main application of Enamelled Enamelled Aluminium wire is in winding of Motor and Transformers.

Enamelled round copper wire is defined as round copper wire used in electrical or wire work that has been painted with matching insulating paints after baking, in compliance with customer requirements, based on a particular mold drawing, and having the required compatibility and temperature resistance index of insulating paint. Transformers, generators, motors, reactors, and other electrical equipment can all be wound with this device.

Yubian Transformer is a professinal transformer manufacturer with serious of certifications.These transformers find applications in power generation, transmission, industrial settings, substations, and other fields. Yubian Transformer specialize in crafting tailored solutions to meet your project's unique requirements.
The oil-immersed transformer is characterized by its big capacity, low loss, low cost, and effective heat dissipation.The conversion of electric energy, or the conversion of voltage level, is its primary function in the power grid. 
It is known that Oil Immersed Transformers account for the majority of power transformers in use in the electrical grid.
A high-performance transformer with a more sensible construction and superior performance is the oil-immersed transformer.Electrical steel strip is used to make the iron core, and laminations at every level are manufactured in accordance with the section shape of the iron yoke and iron core column.To minimize eddy current loss and hysteresis loss, each lamination needs to be stacked in order. As a result, the three things are balanced, the performance is further enhanced, the loss and noise are decreased, and the third harmonic component is decreased.This product is better suited for combination transformers, prefabricated transformer substations, industrial and mining firms, and power grid transformers in both urban and rural areas. 
Oil is used as the primary insulation material for oil-immersed transformers, which also use oil as a cooling medium for forced oil circulation, oil-immersed air cooling, oil-immersed water cooling, and oil-immersed self-cooling.Iron core, winding, oil tank, conservator, respirator, pressure relief valve, radiator, insulating sleeve, tap changer, gas relay, thermometer, etc. are the key parts of the transformer.
Because the transformer oil has an elastic buffer and can seep into the silicon steel sheets for an extended period of time, the oil immersed transformer has low noise.
The iron core and winding are placed and transformer oil is put in the oil tank, which is the transformer's outer shell.The heat pipe or radiator for the large capacity transformer is mounted outside to the oil tank.A significant role is played by the oil conservator in common oil submerged transformer oil, and this oil conservator is more important.Another name for the conservator is oil tank.Temperature changes cause the transformer oil to expand in the heat and contract in the cold. They also cause the oil level to climb or fall.The purpose of the conservator is to maintain the oil tank consistently filled of oil by providing a buffer space for the thermal expansion and cold contraction of the oil;At the same time,due to the oil conservator,the contact area between oil and air is reduced,which can slow down the oxidation of oil.
