Process flow

GRL adheres to the principle of “excellence” in the production of hard bus bars, ensuring that every product has excellent performance, precision and reliability:

Selection of high-quality raw materials:
- We strictly select high-purity oxygen-free copper (T2/C11000) or high-conductivity aluminum alloy that meets international standards, which is the basis for ensuring the electrical properties and mechanical strength of products. All raw materials have undergone strict chemical composition and physical properties testing.
Precision forming processing:
- Advanced CNC cutting, high-precision stamping, CNC bending and CNC milling equipment are used to accurately shape cutting and three-dimensional forming the bus bar. Whether it is linear, L-shaped, Z-shaped, or more complex special-shaped structures, we can ensure its geometric size and fitting accuracy.
- Drilling and tapping: Use high-precision CNC machine tools for precise hole positioning and thread tapping to ensure reliable connection of fasteners.
Advanced joining and welding technology (optional):
- For hard busbars that require multiple layers of lamination or connection with other conductors, we may use advanced technologies such as friction welding, laser welding or diffusion welding to ensure that the connection points have extremely low contact resistance and high mechanical strength, and eliminate the risk of virtual connection and overheating.
Surface treatment (optional):
- According to customer needs and application environment, the surface of the busbar shall be tinned, nickel, silver or passivated. These treatments can effectively improve oxidation resistance and corrosion resistance, improve electrical contact effects, and extend product life.
Insulation treatment (optional):
- For hard busbars that require insulation protection, we offer a variety of high-performance insulation solutions, such as dipping, extrusion, heat shrinkable sleeve or insulating powder coating. All insulation processes are strictly controlled in thickness and uniformity to ensure excellent dielectric strength and safety protection.
Strict quality inspection:
- Carry out comprehensive quality control and performance testing for each batch of hard busbars, including:
  - size accuracy testing: Use precision equipment such as a coordinate measuring machine to verify the geometric size.
  - Conductivity test: resistance test, current-carrying temperature rise test to ensure that electrical performance requirements are met.
  - Hardness testing and tensile strength testing: Verify the mechanical properties of the material.
  - Insulation withstand voltage test (if there is an insulating layer): High-voltage breakdown test to verify the dielectric strength and safety of the insulating layer.
  - Salt spray test, high and low temperature cycle test: Simulate harsh environments and verify the environmental resistance of products.
  - Visual inspection: Ensure that the product surface is smooth and free from defects.

Jinlale’s hard bus bar is widely used and is the core component of various high-current electrical systems:

Power transmission and distribution system: High and low voltage switchgear, distribution boxes, transformer bus connections, power plants and substations.
new energy field: Electric vehicle battery module connections, energy storage systems, wind/solar inverters, charging piles.
industrial control and automation: Industrial control cabinet, MCC (motor control center), frequency converter, rectifier.
rail transit: Electric traction system for locomotives and subway vehicles.
data center: Power distribution system inside the server cabinet.
large equipment: Welding equipment, electric furnaces and other high-current equipment.

GRL mainly provides hard buses of the following two high-performance materials:

High-purity oxygen-free copper (T2/C11000): It has excellent electrical and thermal conductivity and is currently recognized as one of the best conductive materials. It is the first choice in most high-power applications that require extremely high electrical conductivity.
high-conductivity aluminum alloy: It is lightweight and cost-effective. It is an ideal alternative in applications with strict weight requirements (such as lightweighting electric vehicles) or budget sensitive.

We will recommend the most suitable material based on your specific application needs, performance requirements and cost considerations.

GRL offers a variety of surface treatments to meet the needs of different applications and environmental conditions:

tinned: The most common treatment method can effectively prevent oxidation and corrosion, improve solderability, improve contact performance under low voltage and high current, and extend product life. It is especially suitable for use in humid or corrosive gas environments.
nickel plating: Provides stronger wear and corrosion resistance, is suitable for higher temperatures and harsh chemical environments, and has higher hardness.
banhado a prata: Provides excellent conductivity and lowest contact resistance, suitable for applications where signal transmission requirements are extremely high or extremely low resistance is required, but the cost is high.
passivation: A dense oxide film is formed on the surface of the busbar to improve corrosion resistance, but usually does not change the electrical properties.

When selecting the appropriate cross-sectional area of hard bus bar, the following key factors need to be considered:

rated working current: This is the main determining factor. The hard bus needs to be able to safely and continuously carry the maximum working current, with sufficient safety margin.
Temperature rise limit: Under the maximum current, the temperature rise of the bus bar should be controlled within the maximum allowable working temperature range to avoid overheating causing performance degradation or equipment damage.
ambient temperature: Higher ambient temperatures will reduce current carrying capacity and require a corresponding increase in cross-sectional area.
installation method: Ventilation and heat dissipation conditions (such as horizontal installation, vertical installation, and enclosed spaces) can significantly affect current carrying capacity.
Voltage drop requirements: In some applications that are sensitive to voltage drops, products with larger cross-sectional areas need to be selected to reduce resistance.
mechanical strength requirements: Consider the support method, span and possible mechanical stress of the bus bar.

GRL’s professional engineers can provide detailed current-carrying data and technical support to assist you in accurate selection and design.

Yes, GRL always adheres to the highest standards of production and quality management. Our production processes strictly follow ISO 9001 Quality Management system。

During the design and manufacturing process, hard busbar products refer to and comply with relevantInternational and domestic electrical standards(IEC, UL, GB, etc.).

We can provide the corresponding material composition analysis report, electrical performance test report (such as resistance, current carrying capacity, temperature rise), mechanical performance test report and environmental reliability report (such as salt spray test) according to customer requirements to ensure that the product is safe and reliable, excellent performance, so that you can choose at ease.
