Shenzhen Jianhong Jitai Technology Co., Ltd.

Craftsmanship manufacturing, power guarantee: Step into our intelligent production line for high-power resistors and load cabinets.
As a professional manufacturer of high-power resistors and load cabinets, we are well aware of the crucial significance of reliability and accuracy for power systems. Relying on advanced equipment, rigorous craftsmanship and a strict quality control system, we have established an efficient and collaborative production line to ensure that every product can stand up to rigorous tests.

High-power resistors: Engineered for Accuracy & Reliability
Our resistor production line is a perfect combination of precise craftsmanship and strict quality control:

Precision assembly: Starting from assembling the core retaining ring, a solid foundation is laid.

Core winding: Six high-performance professional winding machines operate day and night, precisely controlling the arrangement and tension of the resistance wire (strip) to ensure the initial accuracy of the resistance value. This is the core guarantee of our production capacity.

Reliable connection: Precise welding process ensures the firmness of electrical connection and low contact resistance.
The first checkpoint - full resistance value inspection: After the welding is completed, 100% full resistance value inspection is carried out to eliminate any minor deviations and ensure that no substandard products flow into the next process.

Enhanced protection: Evenly coated with high-performance oxide film, it provides excellent anti-oxidation, high-temperature resistance and insulation protection for the resistor body.

Stable curing: Precise temperature control baking ensures dense curing of the oxide film, with long-lasting and stable performance.

Secondary verification - Re-checking the resistance value: After baking, conduct a 100% full resistance value check again to ensure that there is no performance deviation during the process.
Safety Barrier - Full Inspection of Withstand Voltage Insulation: 100% high-voltage withstand voltage and insulation resistance tests are conducted to build a solid electrical safety defense line.

Finished product integration: Qualified resistor cores are precisely assembled with the casing, heat sink, etc., to form a complete resistor unit.

Protective factory delivery: Professional packaging to ensure transportation safety.

Scale and strength: With the efficient operation of 6 core winding devices, our resistor production line has a powerful monthly output capacity of over 60,000 pieces, meeting your stable demands for large quantities and high quality.

 Customized Load Cabinets: Full Control from blueprint to finished product
The production of load cabinets begins with your needs and ends with your satisfaction.
Demand Insight: In-depth communication to accurately grasp your testing goals, power levels, functional requirements and application scenarios.
Solution customization: Based on your requirements, we tailor the best technical solution and configuration for you.
Collaborative design: A professional team of engineers simultaneously conducts precise circuit design and robust cabinet structure design.
Core self-production: Place an order to start the production of core components - high-power resistors (using our own efficient production line) and customized cabinets.
Strictly select external partners: Simultaneously purchase key components such as circuit breakers, contactors, instruments, and control systems, and strictly screen qualified suppliers.
Full inspection upon entry to the factory: All purchased components and self-produced parts undergo 100% strict incoming inspection to ensure zero defects in basic materials.
System integration: In the professional assembly area, the qualified resistance units and components are precisely integrated into the cabinets according to the design, with neat and standardized wiring.
Functional verification: After the assembly is completed, conduct a comprehensive system functional test and performance verification, simulate actual working conditions, and ensure that every indicator (such as power loading, step accuracy, data acquisition, protection functions, etc.) is perfectly met.
All set to go: The load cabinets that have passed the final inspection will be protected and packaged, and are ready to be sent to your site.

Our core advantages:
Vertical integration: Core resistors are independently produced, ensuring both quality and delivery time.
Double full inspection: During the production process of resistors, there are two 100% resistance value full inspections and one 100% safety full inspection, with quality controlled at every level.
Scale production capacity: Modern resistor production line, with a monthly output of over 60,000 units, supporting load cabinets and external demands.
Strict quality control: A comprehensive inspection system covering the entire process from the entry of components into the factory to the delivery of finished products.
Deep customization: Focusing on understanding requirements and providing load solutions that truly fit the application.
Reliable manufacturing process: A mature and stable technological flow ensures the consistency and long service life of the products.
Choosing us means choosing a reliable power testing partner. We will continuously optimize the assembly line, providing you with more exquisite craftsmanship, more reliable quality and more efficient delivery to ensure the success of your project.

Uncompromising Quality: The Foundation of Our High-Power Resistors & Load Banks

At Jianhong Jitai Technology Co., Ltd, quality isn't just checked; it's engineered into every step of our manufacturing process. We operate under rigorous international standards and implement a comprehensive, multi-layered quality control system to guarantee the exceptional performance, safety, and reliability our customers demand.

Our Core Quality Commitment for High-Power Resistors:

Dual 100% Resistance Verification: Every single resistor undergoes not one, but two complete 100% resistance value inspections:

*  Post-Winding/Welding: Ensuring initial accuracy immediately after core formation.

*  Post-Baking/Curing: Verifying stability after the critical oxide coating process. This dual-check guarantees precision throughout manufacturing.

Mandatory Safety Assurance: 100% of our resistors undergo rigorous Dielectric Strength (HiPot) and Insulation Resistance testing. This non-negotiable step ensures every unit meets the highest electrical safety standards before final assembly.

End-to-End Quality Management System:

Our commitment extends far beyond the resistor core to encompass our entire operation, including custom load banks:

    Incoming Material Inspection: 100% verification or strict sampling plans applied to all incoming components, raw materials, and sub-assemblies against defined specifications. Only certified materials enter production.

    First Article Inspection (FAI): Thorough validation of the first piece produced from any new setup or process change, ensuring conformance before full production runs.

    In-Process Controls: Systematic monitoring and checks at defined critical points within the manufacturing flow (e.g., during resistor winding, coating, load bank assembly, wiring) to detect and correct deviations immediately.

    Final Product Performance Testing: Comprehensive 100% functional and performance testing on finished products (both resistors and load banks). This includes simulating operational conditions to validate all specifications – power handling, accuracy, control functions, and safety features – are met or exceeded.

Certified Excellence:

Our processes and commitment are validated by internationally recognized certifications:

*  ISO 9001:2015 Certified: Our Quality Management System adheres to this global benchmark, ensuring consistent processes, continuous improvement, and customer focus.
