Lead Wire Manufacturers Help You Solve The Problem Of Hard Leads Caused By The Immersion And Baking Process Of Motor Windings?

Lead wire manufacturers help you solve the problem of hard leads caused by the immersion and baking process of motor windings?

After the motor winding is immersed, the hardening of the connection is a problem that most manufacturers often encounter. Different manufacturers have different dipping process solutions, and the situation, severity and solution of the problem are different, which will correspond to different specific operating procedures, but the goal and concept are the same.

Most of this problem occurs with motor products with relatively large lead diameters. No matter what kind of lead wire, as long as there is insulation paint penetrating into the wire core, the lead wire will harden after drying, especially for the case of large wire warp, the problem mostly occurs in motor products with relatively large lead wire diameter. No matter what kind of lead wire, as long as the insulating paint penetrates into the core, the lead wire will harden after drying, especially for the case of large wire diameter, it is almost impossible to carry out subsequent wiring and assembly. In view of this problem, on the one hand, we must ensure that the corrosion resistance and heat resistance of the lead wire meet the requirements, that is, the insulation skin of the lead wire will not deteriorate during the immersion process, which is mainly related to the quality of the lead wire itself and whether the selection is reasonable.

 On the other hand, how to ensure that the insulating paint does not enter the core of the lead wire during the immersion process, which seems to be the simplest but the most difficult problem to solve. One of the simplest and roughest methods is that the motor lead wire is carried out after the completion of the immersion and baking process, but how to ensure the connection of the lead wire and the re-insulation treatment of the winding after lashing is a new problem with many hidden dangers, which is obviously simple and easy to implement, and the hidden dangers are its characteristics; Another method avoids the rough practice of leaving hidden dangers, and solves the problem of paint penetration of the lead core before dipping the paint, the specific method is: first weld the lead and the wire, and then use a self-adhesive tape that can be fused with the lead insulating layer material and itself, densely block the solder joint, and the other end of the lead wire is also wrapped and blocked with self-adhesive tape, thereby isolating the air in the lead core from the outside air, basically solving the penetration problem of insulating paint, which is undoubtedly a good way to fundamentally solve the problem.

 Wire and cable structure and materials The vast majority of wire and cable products are products with identical cross-sectional shapes and long strips, which are determined by the characteristics of use as a circuit or coil in the system or equipment.

 The structural components of wire and cable products can be generally divided into four main structural components: wire, insulation, shielding and sheath, as well as filling elements and tensile elements. According to the use requirements and application of the product, some product structures are extremely simple.

 In a sense, the wire and cable manufacturing industry is an industry of material finishing and assembly. First, the amount of materials used is huge, and the material cost in cable products accounts for 80-90% of the total manufacturing cost; Second, there are many types and varieties of materials used, and the performance requirements are particularly high, such as copper for conductors, the purity of copper is required to be more than 99.95%, and some products should use oxygen-free high-purity copper; Third, the selection of materials will have a decisive impact on the manufacturing process, product performance and service life.

The benefits of wire and cable manufacturing enterprises are closely related to whether the selection, processing and production management of materials can be scientifically saved. According to their use parts and functions, cable products can be divided into conductive materials, insulation materials, filling materials, shielding materials, sheath materials, etc. But some of these materials are common to several structural parts. In particular, thermoplastic materials such as polyvinyl chloride and polyethylene can be used in insulation or sheathing as long as part of the formula composition is changed. The materials used in the manufacture of cable products involve a wide range of categories, and there are many varieties and specifications.

The wire is the most basic and indispensable main component of the product for the function of transmitting current or electromagnetic wave information. Conductor is the abbreviation of conductive wire core, made of copper, aluminum, copper-clad steel, copper-clad aluminum and other non-ferrous metals with excellent conductivity, with optical fiber as the wire. There are bare copper wire, tin plated wire; Single branch, stranded wire; Tin plating wire after twisting, etc. An insulating layer is a component that acts as electrical insulation around the perimeter of a conductor. That is, it can ensure that the transmitted current or electromagnetic waves, light waves only travel along the wire and do not flow to the outside, and the potential energy on the conductor can be isolated, that is, to ensure the normal transmission function of the wire, but also to ensure the safety of external objects and people. Conductors and insulation are the two basic building blocks that must be present to make up cable products.

The insulation layer materials mainly include PVC, PE, XLPE, polypropylene PP, fluoroplastic F, rubber, paper, mica tape, etc. Many wire and cable products are multi-core, after these insulated cores or wires into cables, one is not round, the other is that there is a large gap between the insulated cores, so it is necessary to add a filling structure when forming a cable, and the filling structure is to make the outer diameter of the cable relatively round to facilitate the wrapping and extrusion sheath.

Shielding is a component that isolates the electromagnetic field in the cable product from the electromagnetic field outside; Some cable products also need to be isolated from each other between different wire pairs or wire groups inside. It can be said that the shielding layer is a kind of "electromagnetic isolation screen". The conductor shielding and insulation shielding of high-voltage cables are used to homogenize the distribution of the electric field.

The sheath is a component that must protect the product as a whole, especially the insulation layer, when the wire and cable products are installed and operated in a variety of different environments, which is the sheath.

purity and minimal impurity content of the material; It is often impossible to take into account its ability to protect the outside world, so the bearing or resistance of various mechanical forces of the outside world, resistance to atmospheric environment, chemical or oil resistance, prevention of biological invasion, and reduction of fire hazards must be borne by various protective layer structures. The typical structure of tensile elements is steel core aluminum stranded wire, optical fiber cable cable, etc. In short, tensile elements play a major role in the development of particularly small, flexible types that require multiple bending and twisting products.
