Conductor  Drawing  

1. Large Drawing:
Copper rods with a diameter of 6mm are drawn down to approximately 2.6mm.

2. Medium Drawing:
Copper rods with a diameter of 2.6mm are drawn down to approximately 0.8mm.

3. Fine Drawing:
Copper wires with a diameter of 0.8mm are drawn down to approximately 0.2mm.

4. Copper Wire Annealing: 
Vacuum furnace can be used for centralized annealing or continuous drawing annealing.

5. Medium Drawing: 
Can be performed using single-head drawing or multi-head drawing, with a preference for multi-head drawing. 

Conductor Stranding  

1. Frame Twisting:
This method is used for twisting large cross-sectional conductors. It features a single-pitch pay-off reel, which results in low efficiency. The lack of a back twist function means that the twisted product retains stress from the twisting process, making the conductor relatively stiff.

2. Cage Twisting:
Suitable for large or medium cross-sectional conductors, this technique also uses a single-pitch pay-off cage, leading to low efficiency. However, it includes a back twist function, which eliminates stress from the twisting process, resulting in a more flexible conductor.

3. Bundle Twisting:
Designed for small cross-sectional conductors, this method employs an angular bow double-pitch structure, offering high efficiency. Similar to frame twisting, it lacks a back twist function, so the twisted product retains stress, and the conductor is relatively stiff.

4. Customers select the twisting process and the number of machines based on their production requirements.

Core Wire Extrusion  

1. Core Extrusion Line Configuration:
A 90-120 extruder is generally selected, compatible with materials including PVC, PE, TPE, TPU, LSZF, XLPE, and XLPVC etc.

2. Auxiliary Equipment Configuration:
* Double-head passive payoff
* Front tension capstan (caterpillar or double-wheel type)
* Straightening wheel
* Strip injection machine (optional)
* Movable water cooling tank
* Printer
* 15-meter water cooling tank
* Double-wheel capstan or caterpillar capstan
* Accumulator frame (optional)
* Large spool take-up

3. Optional Testing Equipment can be selected for additional specific needs:
* Spark tester
* Laser diameter gauge
* Etc.

Cabling     

1. Cabling Main Twister Configuration: 
For large or medium cable cross-sectional areas cabling, a planetary stranding machine is typically used; 

For small cable cross-sectional areas cabling, a cantilever stranding type is used for multi core wire stranding.

2. Auxiliary Equipment Configuration:
* Taping machine
* Armor wrapping machine (optional)
* Capstan
* Take-up
* Pay-off, the number of pay-off heads depending on customer demand.

3. Optional Testing Equipment can be selected for additional specific needs:
* Spark tester
* Etc.

Braided Shielding  Layer  

1. Standard Power Cable Production Configuration:
Standard power cables are manufactured without a braiding process. However, by integrating a braiding machine, the production line can be expanded to accommodate various other cable types.

2. Braiding Machine Configuration:
Braiding machines with 16 to 24 spindles are typically employed.

3. Optional Braiding Machine Features:
Braiding machines can be equipped with either mechanical pitch control or electronic pitch control. 

Sheath Extrusion  

1. Sheathe Extrusion Line Configuration: 
A 90-150 extruder model is typically selected, suitable for PVC, PE, TPE, TPU, LSZF, XLPE, and XLPVC etc.

2. Auxiliary Equipment Configuration: 
* Single-head large spool passive pay-off
* Front tension capstan (caterpillar or double-wheel type)
* Powder machine
* Movable water tank
* Oil ink printer (or inkjet coder)
* 15-meter water tank
* Caterpillar capstan
* Large spool take-up
* Etc.

3. Testing Equipment: 
* Spark testers
* Diameter gauges devices
* Etc.
