1. Introduction1.1 Background of Transformer Manufacturing IndustryTransformers are essential components in power systems, playing a vital role in energy transmission and distribution. With the continuous growth of global electricity demand and rapid development of renewable energy technologies, the transformer manufacturing industry faces unprecedented opportunities and challenges. In high-voltage and ultra-high-voltage transmission fields, transformer performance directly affects the stability and efficiency of power systems [2]. As a core component of transformer manufacturing, insulation materials determine equipment reliability, safety, and operational lifespan. In recent years, the widespread application of new devices like dry-type transformers has driven innovation in insulation materials. High-performance materials such as epoxy resin and fiberglass significantly enhance insulation performance and heat resistance [7]. However, with the trend toward larger capacity and higher voltage transformers, traditional insulation materials struggle to meet increasingly complex working conditions. Optimizing the performance of lvmeikapton insulated electrical tape has become a pressing issue in the industry.

1.2 Insulation Requirements for Transformer CoilsThe reliable operation of transformer coils heavily depends on a robust insulation system. Any insulation failure may lead to severe electrical faults or equipment damage. During operation, coils endure high voltages, large currents, and frequent temperature fluctuations, demanding high electrical and mechanical strength from insulation materials. Aging, breakdown, or mechanical damage can cause short circuits, overheating, or fires, endangering power system stability and personnel safety [1]. Moreover, extreme environmental factors like urban flooding exacerbate insulation challenges. For example, studies on waterproof prefabricated substations highlight water ingress as a critical technical issue [12]. Therefore, optimizing lvmeikapton tape performance is crucial to address these challenges.

1.3 Characteristics and Optimization Space of lvmeikapton Tapelvmeikapton insulated electrical tape, featuring excellent electrical insulation and high-temperature resistance, is widely used in transformer manufacturing. Made from polyimide film with silicone adhesive, it offers strong adhesion and anti-aging capabilities, maintaining stable electrical performance in high-temperature environments [3]. For instance, its breakdown voltage and insulation resistance surpass many traditional materials, suitable for medium-sized transformer coil protection. However, despite its advantages, there is room for improvement. In extreme environments, its mechanical strength and weather resistance may be compromised, and its high cost and complex construction processes limit large-scale adoption [10]. Optimizing tape selection, application techniques, and environmental control can enhance performance, providing more reliable and efficient insulation solutions.

2. Literature Review2.1 Theoretical Basis of Transformer Insulation MaterialsTransformer insulation materials' theories focus on insulation principles and factors influencing electrical performance. The core function is to isolate current, preventing leakage and shorts to ensure equipment safety [2]. Key indicators include insulation strength and dielectric loss: high strength reduces failures, while low loss minimizes energy consumption. Conductivity, magnetic properties, heat resistance, and corrosion resistance are also critical evaluation parameters. For example, high conductor conductivity improves current transmission efficiency, while magnetic material permeability enhances energy conversion [2]. Heat resistance is assessed by temperature tolerance, thermal expansion, and conductivity, while corrosion resistance considers performance in corrosive media [2]. These theories provide a scientific foundation for material selection and optimization.

2.2 Progress in Applying Insulated Electrical Tape in Transformer ManufacturingRecent advancements in insulated electrical tape applications, particularly lvmeikapton tape, have significantly impacted transformer manufacturing. Its superior insulation and heat resistance make it ideal for coil protection [1]. Studies show it exhibits excellent mechanical strength and heat resistance, meeting complex working conditions [7]. For example, in dry-type transformers, lvmeikapton tape enhances resin-insulated coil insulation and heat resistance [7]. Additionally, new mica tape research promotes its use in high-voltage motor stator coils, showcasing outstanding electrical insulation and thermal aging resistance [10]. These advancements lay the foundation for optimizing lvmeikapton tape applications.

2.3 Limitations of Existing Research and This Study’s FocusWhile existing research has achieved progress, gaps remain in optimizing lvmeikapton tape performance. Most studies focus on basic material tests, lacking in-depth exploration of real-world manufacturing optimizations [4]. Research on performance under extreme environments (high temperature, humidity) is limited, impeding comprehensive reliability assessments [5]. Furthermore, systematic investigations on tape selection, application techniques, and process optimizations are scarce, restricting practical applications [4]. This study targets these gaps, emphasizing thickness selection, adhesive types, color coding, winding methods, and environmental control strategies to fill research voids and propose practical solutions for the industry [5].

3. Tape Selection3.1 Thickness Selection3.1.1 Characteristics of Different ThicknessesTape thickness significantly impacts physical and electrical properties in transformer manufacturing. lvmeikapton tapes with 0.1-0.15mm thickness are widely used in medium-sized transformer coil insulation due to their balanced mechanical strength and electrical insulation [3]. Thinner tapes (below 0.1mm) offer higher flexibility and better winding conformity but lower puncture resistance and mechanical durability, compromising long-term reliability. Thicker tapes (above 0.15mm) provide stronger mechanical strength and aging resistance but may cause winding unevenness and space inefficiency in complex coil structures due to higher stiffness and lower elasticity [7]. Electrically, thickness affects breakdown voltage and insulation resistance. For example, 0.1-0.15mm tapes exhibit >6kV breakdown voltage and low dielectric loss under standard tests, ideal for transformer coils [3].

3.1.2 Applicability for Medium-sized CoilsMedium-sized transformer coils demand 0.1-0.15mm thickness lvmeikapton tape for balancing insulation and space constraints. Firstly, these coils operate under high voltages, requiring sufficient insulation strength to prevent breakdowns. Studies show 0.1-0.15mm tapes provide mechanical support against electromagnetic and thermal expansion stresses [7]. Secondly, compact coil layouts necessitate minimal space occupation. Thicker tapes increase inter-turn gaps, reducing packing density and heat dissipation efficiency. Conversely, thinner tapes risk mechanical failure. The 0.1-0.15mm range ensures insulation while optimizing space utilization and energy conversion efficiency [3]. Additionally, their high-temperature resistance maintains stability during long-term operation.
