Aluminum Braid

Aluminum Braid Description

CVSIC Aluminum Braid (also known as Flexible Aluminum Connection Braid, Aluminum Cooling Braid, or Aluminum Foil Braid) is a specialized accessory for silicon carbide (SiC) heating elements, used to connect SiC elements to external power sources for efficient conductivity and heat dissipation. Made from multi-strand, high-conductivity fine aluminum wires combined with stainless steel, it offers flexibility, high-temperature resistance, and corrosion resistance, with a current capacity of 25-400A. Available in single-hole and double-hole designs to meet various wiring needs, it provides a dependable connection for industrial heating systems in high-temperature furnaces, electronic semiconductors, lithium batteries, and more.

Ordering Information

When ordering Aluminum Braid, please provide the following parameters:

• SiC Element Diameter: Match the cold end diameter of the heating element
• Rated Current: 25/50/100/200/400A
• Type: Single or double-hole
• Length: Specific length (at least 25mm longer than the straight-line distance from the cold end to the busbar)
• Example: Single-hole aluminum braid, for 14mm diameter SiC element, 100A current, 200mm length
• Note: Customizable specifications (8-48 spindles, single or multi-layer braiding) based on customer requirements or samples.

Aluminum Braid Connection Method

• Installation Position: The aluminum braid is fixed to the aluminum-coated cold end of the SiC heating element, connecting it to the external power source.
• Connection Method:
  1. Secure the aluminum braid to the cold end with a steel clip and screw, and connect the other end to the busbar using an aluminum crimp.
  2. Ensure the length is at least 25mm longer than the straight-line distance from the cold end to the busbar to avoid mechanical stress.
  3. Adjust the aluminum braid before installation, tightening the screws evenly to prevent bending or external force on the element.
  4. Connect the busbar first, then attach to the SiC element one by one, ensuring good contact with connection end voltage <0.01V.
  5. After the furnace reaches operating temperature for 2-3 hours, re-tighten the screws to address thermal relaxation.
• Note: Multi-strand fine aluminum wire design supports high currents, paired with stainless steel spring clips for stable connections and superior heat management. Use an SCR voltage regulator (a temperature control device) to optimize performance.

Aluminum Braid Installation Method

To ensure the performance and safety of the Aluminum Braid, follow these steps:

1. Inspect Accessory: Confirm the aluminum braid is undamaged and meets the required length (at least 25mm longer than the straight-line distance).
2. Fix to Cold End: Secure the aluminum braid to the SiC element’s aluminum-coated cold end with a stainless steel spring clip and screw.
3. Connect to Busbar: Fasten the other end to the busbar with an aluminum crimp, ensuring good contact.
4. Adjust Stress: Ensure that no bending or stretching forces affect the element, and tighten screws evenly.
5. Post-Heating Check: After 2-3 hours of furnace operation, re-tighten screws to address thermal relaxation.

Aluminum Braid Design Recommendations

• Match Element Diameter: Select an aluminum braid corresponding to the SiC heating element’s cold end diameter for a stable connection.
• Current Capacity: Choose 25-400A rated current based on SiC element power to avoid overloading.
• Length Design: Ensure length includes a 25mm margin to prevent mechanical stress on the element.
• Installation Space: Use single-hole connections for element-to-terminal connections and double-hole connections for terminal-to-terminal connections, planning the layout accordingly.
• Temperature Control System: Pair with an SCR voltage regulator to optimize current control and extend accessory and element lifespan.
• Regular Maintenance: Check screw tightness during initial operation to prevent thermal relaxation affecting connection performance.
