Wireless Stream

02 · Project Background and Industry Challenges

Transmission and distribution lines require a large number of tower-side sensing and monitoring devices, including cameras, environmental sensors, wireless concentrators, and bird-deterrent devices. These devices are essential for collecting operating data, identifying potential faults, and supporting the condition monitoring and intelligent maintenance of power infrastructure.

However, tower-side equipment is often deployed in remote areas, at high elevations, or under complex environmental conditions. Conventional power supply methods may depend on batteries, wired connections, solar panels, or frequent manual maintenance. These approaches can be limited by battery life, installation difficulty, weather conditions, insulation requirements, and high maintenance costs.

To address these challenges, Wireless Stream proposes a watt-level wireless energy transfer product based on multi-stage magnetically coupled resonant insulators. The system is designed to transmit electrical energy through an integrated insulator structure without relying on conventional conductive wiring across high-voltage insulation boundaries.

Based on existing technical research, the project jointly optimizes system miniaturization, effective power supply distance, and energy transfer efficiency. The objective is to develop a compact and efficient prototype that can provide stable power for tower-side equipment, improve the long-term reliability of transmission and distribution line condition-monitoring systems, and support the digital transformation of the power grid and the development of the Energy Internet.

03 · Overall Technical Architecture

Wireless Stream combines multi-stage magnetic resonance coupling, wireless power transfer, high-voltage insulation design, integrated packaging, tower-side sensing, and system-level performance optimization.

The system uses multiple resonant coupling stages to extend the effective energy transfer path. Each stage contains a resonant module composed of coils and circuit components. By designing the resonant frequency, coupling coefficient, coil parameters, circuit topology, load characteristics, and spatial arrangement of each module, electrical energy can be transferred through the multi-stage structure while maintaining practical transmission efficiency.

The magnetic resonance modules are integrated with a high-voltage insulator structure. This enables the system to perform two functions simultaneously: maintaining the electrical insulation required by transmission and distribution infrastructure and transmitting watt-level power to sensing equipment installed on the tower side.

The complete technical architecture includes three main areas:

1. Enhanced wireless energy transfer based on multi-stage magnetic resonance coupling.

2. Structural design and insulation packaging of high-voltage insulators integrated with multi-stage magnetic resonance modules.

3. Tower-side sensing applications and deployment based on the developed wireless power transfer system.

Through the coordination of these areas, the project connects theoretical modeling, simulation analysis, structural development, prototype integration, performance testing, and field validation into a complete research and development process.

04 · Multi-Stage Magnetic Resonance Coupling and Efficiency Enhancement

The first research area focuses on modeling, simulation, and efficiency enhancement for the multi-stage magnetically coupled resonant wireless power transfer system.

A coil model is developed to describe the electromagnetic coupling among the transmitting coil, intermediate resonant coils, and receiving coil. The model is used to evaluate how coil geometry, coil spacing, number of resonant stages, alignment, mutual inductance, and coupling coefficients affect the overall transmission performance.

A corresponding circuit model is also constructed to analyze the electrical characteristics of the complete system. The model covers resonant parameters, input and output power, voltage and current characteristics, equivalent impedance, load matching, and transmission efficiency.

Based on the coil and circuit models, simulation analysis is conducted to study the relationship between system electrical parameters and energy transfer performance. Different configurations are compared to identify the major sources of energy loss and determine suitable system parameters.

The project also investigates methods for improving transmission efficiency. These methods include resonant frequency matching, coil structure optimization, coupling enhancement, compensation network design, load matching, and coordinated parameter optimization across multiple resonance stages.

The feasibility of each performance-enhancement method is evaluated through simulation and prototype verification. The objective is to maintain stable watt-level energy output while increasing the effective power supply distance and reducing unnecessary energy loss.

05 · High-Voltage Insulator Structure and Integrated Packaging

The second research area focuses on the structural design, insulation packaging, simulation optimization, development, and testing of an integrated device combining multi-stage magnetic resonance modules with a high-voltage insulator.

The insulation packaging structure must protect the internal coils and circuit modules from moisture, dust, mechanical impact, temperature variation, and long-term outdoor exposure. At the same time, it must maintain the insulation performance required by transmission and distribution systems and avoid significantly reducing wireless energy transfer efficiency.

The project designs an integrated insulation structure suitable for embedding or assembling multi-stage magnetic resonance modules. Electric field simulation is performed to analyze the field distribution around the insulation structure. Areas of electric field concentration are identified, and the geometry, dimensions, material configuration, and module arrangement are optimized accordingly.

The project develops an implementation plan for integrated insulation packaging. The plan covers material selection, structural processing, manufacturing methods, process control, module assembly, sealing, and quality testing.

Different insulation materials, packaging thicknesses, structural dimensions, and resonant module arrangements may alter the electromagnetic coupling characteristics of the system. Therefore, the project investigates the influence of the insulation package and insulation structure on the energy transfer efficiency of the multi-stage magnetic resonance modules.

Based on the optimized design, an integrated prototype device is developed and tested. The testing process evaluates electrical insulation, structural reliability, energy transfer performance, power output, efficiency, stability, and environmental adaptability.

06 · Tower-Side Sensing Applications

The third research area focuses on applying the multi-stage magnetically coupled resonant wireless power transfer system to overhead transmission and distribution lines.

The project analyzes the power supply requirements of sensors and other electrical equipment installed on transmission and distribution towers. The analysis considers equipment type, rated power, operating voltage, continuous or intermittent operating mode, installation location, environmental conditions, and reliability requirements.

Based on these requirements, a complete multi-stage magnetic resonance wireless power transfer application system is developed. The system is intended to power watt-level equipment such as tower-side cameras, environmental and condition-monitoring sensors, wireless concentrators, communication modules, and bird-deterrent devices.

Application schemes are designed according to different tower structures, equipment locations, insulation configurations, and power requirements. The project also studies deployment methods, including device installation, transmitter and receiver arrangement, resonant module positioning, load connection, protection measures, inspection, and maintenance.

After the application system is developed, performance trials and laboratory tests are conducted to evaluate its power supply distance, output capability, energy transfer efficiency, load adaptability, operational stability, and insulation characteristics.

Field verification is then carried out in an overhead-line environment to assess whether the system can operate reliably under real deployment conditions. The results provide a basis for improving the system design and preparing it for engineering implementation.

07 · Prototype Development and Testing

The project aims to transform theoretical research and simulation results into a compact and efficient wireless power transfer prototype system.

Prototype development integrates the multi-stage resonant coils, compensation circuits, high-voltage insulator structure, insulation packaging, transmitting unit, receiving unit, and tower-side load interface. Miniaturization is considered throughout the structural and electrical design process so that the system can be deployed without occupying excessive installation space or interfering with existing power infrastructure.

Testing is carried out at the module, subsystem, and system levels. Module-level testing verifies the electrical and resonant characteristics of individual coils and circuits. Subsystem testing examines the performance of multi-stage coupling, insulation packaging, and power conversion components. System-level testing evaluates the prototype under representative loads and installation conditions.

The primary performance indicators include effective power supply distance, output power, transmission efficiency, voltage stability, temperature rise, insulation performance, structural reliability, load compatibility, and long-term operating stability.

The prototype and testing process also verify whether efficiency-enhancement methods, insulation optimization, and the tower-side deployment scheme are technically feasible when integrated into a complete system.

08 · Business Model and Commercialization

The project follows a technology-to-application commercialization model. Based on existing research achievements, the team will continue developing watt-level wireless energy transfer technologies and devices based on multi-stage magnetically coupled resonant insulators.

The product will be jointly optimized in three key dimensions: miniaturization, effective power supply distance, and high energy transfer efficiency. These improvements are intended to transform the research results into a compact, efficient, and deployable prototype system.

Rather than treating wireless power transfer as an isolated laboratory technology, the project connects technical breakthroughs with practical power-grid applications. The integrated product can provide a new and reliable power supply solution for tower-side cameras, wireless concentrators, sensing devices, communication equipment, bird-deterrent devices, and other watt-level loads.

Potential customers and partners include power grid enterprises, power equipment manufacturers, transmission and distribution line monitoring solution providers, sensor manufacturers, communication equipment suppliers, and intelligent operation and maintenance service providers.

The product can be commercialized through integrated device sales, customized development, engineering deployment, technical licensing, and long-term operation and maintenance services. As deployment expands, the system may become part of a broader tower-side sensing and power-supply ecosystem.

By reducing reliance on battery replacement, wired installation, and repeated manual maintenance, Wireless Stream can help lower the lifecycle cost of tower-side monitoring equipment and increase the availability and reliability of power-grid condition-monitoring systems.
