Sunshine Bulk Cat 6 Cable Manufacturing Process

With Sunshine’s expertise in cable production, our in-house cable manufacturing process produces the best premium Cat Cables, we wholesale cat 5 cable and wholesale cat 6 cable.

Step 1: Wire Diameter Reduction Through A Series of Wire Drawing Processes

The first step in manufacturing cable Cat is wire drawing. Wire drawing is a process in which the wire is drawn through a die so as to reduce its diameter and increase its length. As this happens, its volume remains the same.

The dies are flooded with lubricant which also serves as a coolant, increasing the life of the dies and keeping the copper wire from overheating.

The copper wire produced in the first draw will then be transferred to an insulating area of the plant where a second wire draw will be done followed by annealing, before the application of insulation to the copper wire.

Step 2: Softening the Wire Through Annealing

From its brittle state after drawing, the wire needs to be annealed to make it ductile. Annealing is simply the process of heating the copper to a certain temperature and then slowly cooling it.

At this stage, the wire submerged in water is heated up to 1000 deg F for just a moment before taking it out of the water. Submerging it in water prevents oxidation and corrosion of the metal.

Step 3: Wire Extrusion and Insulation

The next step requires the wire to be passed through an extruder where either a single or double coating of plastic is applied. High-density polyethylene pellets are fed into the extruder, heated, and met.

Step 4: Wire Diameter and Insulation Testing

Before the reels move to the next manufacturing operation, wire and insulation diameter are measured, and the wire is tested for electrical properties such as capacitance and resistance.

Step 5: Wire Twisting and Stranding

In this step, the insulated wires are twisted into wire pairs. Each pair has a unique twist length to avoid crosstalk and interference.The wires will now be tested for electrical defects such as crosses, shorts, and opens.

Step 6: Cabling

At this stage, the wires that came out from the stranding process are grouped together forming a multi-unit cable core. The units are also twisted together on a rotating core truck to help control electrical interference and provide flexibility.

Step 7: Jacketing

At jacketing, several operations such as gel-filling, armoring, jacketing, and printing are performed to produce the finished cable.

● Gel-filling and Armoring

The cable core is heated ensuring that the filling compound penetrates possible voids. A filling compound is added to the heated core in the filling chambers. Then finally, a plastic core is wrapped around the cable.

● Metal Sheathing

Depending on the cable design, a protective metal sheathing of either aluminum or aluminum and steel combined may be added during this manufacturing step. The aluminum acts as a grounding path for high-voltage surges that may be caused by lightning strikes and other eventualities in aerial cables, while steel adds mechanical protection for buried cable against pests such as rats and gophers.

● Extrusion of Outer Cable Jacket

The outer cable jacket is extruded in the next step. It is usually made from low-density polyethylene, black in color, and resistant to ultraviolet light in case it is exposed to sunlight. This rugged plastic is the final protection for the enclosed cable against the environmental conditions underground or when strung to utility poles.

● Cooling and Finishing Touches

The jacketed cable then passes through a temperature-controlled water trough, which cools the jacket. The cable is dried, and the top layer of the jacket is heated slightly so that printer markings can be imprinted on it. Because of the heating, the markings are stamped into the jacket itself and will last the life of the cable.

Step 8: Cables Tested Before Shipping

Upon exiting the jacketing operation, the finished cable is wound onto metal or wooden reels and then transported to the final test facility.

● Physical Inspection of the LAN Cable

An inspector checks for the proper placement of units, subunits, and spare pairs within the cable.

● Electrical Test

Electrical tests include a ring-out of all conductors for continuity and a core-to-sheath test. The core-to-sheath test measures minimum voltage requirements between the cable core and the metal sheath; this helps ensure that high-voltage surges, such as lightning strikes, cannot reach the conductors. A high-voltage test is also performed, and all conductors are checked for electrical integrity. Random tests are performed for mutual capacitance, unbalance, and resistance.

● Shipping

Preparing the cable for shipment may include sealing the cable end with a steel or plastic cap, and testing air-core cables for integrity. Such cables are equipped with valves so that dry, pressurized air can be pumped into them to protect them from moisture.

Cat Cable FAQ

  • What is the difference between Cat and Ethernet?

    The term "Ethernet" refers to a family of networking technologies used for local area networks (LANs), while "Cat" (short for Category) refers to the different standards or categories of Ethernet cables. 
    Ethernet encompasses various networking standards and protocols for connecting devices within a local network, such as computers, printers, and routers, allowing them to communicate and share resources. It defines how data is transmitted over the network, including the physical medium (cables), data link layer protocols, and network configuration.
    On the other hand, "Cat" refers to the different categories of Ethernet cables defined by the Electronic Industries Association and Telecommunications Industry Association (EIA/TIA). These categories, such as Cat5, Cat6, and Cat7, specify the performance characteristics and capabilities of Ethernet cables, including data transmission speeds, maximum frequencies, and shielding requirements. 
    In summary, "Ethernet" refers to the networking technology, while "Cat" refers to the standards or categories of Ethernet cables used to implement Ethernet networks.
  • Which cat cable is best?

    The best Cat cable depends on your specific networking requirements and budget. Generally, newer Cat cables offer higher performance and better shielding against interference, but they may also be more expensive. Here's a brief overview:
    Cat5e: Suitable for basic networking needs and supports data transmission speeds up to 1 Gigabit per second (Gbps). It's a cost-effective option for most home and small office networks.
    Cat6: Offers improved performance compared to Cat5e, supporting data transmission speeds up to 10 Gbps over shorter distances. It provides better resistance to crosstalk and interference.
    Cat6a: Similar to Cat6 but with improved performance and support for higher frequencies, allowing for data transmission speeds up to 10 Gbps over longer distances. It's suitable for demanding applications and environments with high interference.
    Cat7 and above: These cables offer even higher performance and better shielding compared to Cat6a, supporting data transmission speeds up to 10 Gbps or more over longer distances. They are ideal for high-speed networking applications and environments with extreme interference.
    Ultimately, the "best" Cat cable for you depends on factors such as the required data transmission speeds, distance, and level of interference in your networking environment, as well as your budget.
  • Is there a Cat8 cable?

    Yes, there is a Cat8 cable. Cat8 is the latest standard in the Ethernet cable category, offering even higher performance compared to previous Cat cables. It is designed to support data transmission speeds of up to 25 Gigabits per second (Gbps) or even 40 Gbps over distances of up to 30 meters. Cat8 cables feature improved shielding and are suitable for demanding applications and environments where high-speed networking is essential. However, Cat8 cables are still relatively new and may be less widely available compared to lower-category cables.
  • Can I plug a Cat8 cable into a Cat6 jack?

    Yes, you can plug a Cat8 cable into a Cat6 jack. Ethernet cables and jacks are backward compatible, meaning you can use newer cables with older jacks. However, the performance of the connection will be limited by the capabilities of the lowest category component in the setup. In this case, while you can physically connect a Cat8 cable to a Cat6 jack, the data transmission speeds and performance will be limited to the capabilities of the Cat6 infrastructure. To fully leverage the capabilities of a Cat8 cable, it's recommended to use it with compatible Cat8 jacks and networking equipment.
  • CAT 5 VS. CAT 6

    When comparing Cat5 and Cat6 Ethernet cables:
    Performance: Cat6 cables offer higher performance compared to Cat5. Cat5 cables support data transmission speeds up to 1 Gigabit per second (Gbps), while Cat6 cables can support speeds up to 10 Gbps.
    Construction: Cat6 cables typically have more stringent specifications for construction and shielding compared to Cat5 cables, resulting in better resistance to crosstalk and interference.
    Compatibility: Both Cat5 and Cat6 cables are backward compatible, meaning they can be used with older networking equipment. However, Cat6 cables offer future-proofing for higher-speed networking applications.
    Cost: Cat6 cables are generally more expensive than Cat5 cables due to their higher performance and construction specifications.
    Overall, Cat6 cables are a better choice for applications requiring higher data transmission speeds and better performance, while Cat5 cables may suffice for basic networking needs at a lower cost.
  • How can I choose the right Cat cable?

    To choose the right Cat cable for your needs, consider the following factors:
    Data Transmission Speed: Determine the data transmission speed required for your networking applications. Higher category cables, such as Cat6 and above, offer higher speeds compared to lower categories like Cat5e.
