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.

Why Choose Sunshine Cat Cables

Huge Savings on Material, Labor, and Maintenance

Thanks to the modular design of Sunshine Ethernet cable Cat, installation is fairly quick and easy and a lot of time is saved. Initial set-up costs are reduced, and greater reliability and easier and more efficient cable management are expected requiring less maintenance.

Superior Electrical Performance

Electrical performance is best achieved as the twisted conductor pairs are gap-free. This means that the conductor-to-conductor spacing, or centricity, is kept uniform, offering excellent and consistently reliable movement of electrical signals.

High Reliability and Performance with Superb Connectivity

Sunshine Cat cables never fall short of providing reliable connectivity, even in events of losing power or when the wires are damaged. This makes LAN cabling the system of choice to be certain that networks will continue to function properly when needed.

Ease of Splicing/Connection

A space allowance is provided for handling the cable in an easier and safer way to facilitate splicing/connection.

Provides Incredibly Fast and Reliable Communication and Network Speed

The biggest benefit of choosing a wired LAN network over wireless connections is the increased speed that it offers, promoting maximum work uptime.

Cat Cable FAQ

  • What is the difference between Cat and Ethernet?

    Ethernet Cable Differences. To put it in simpler terms, CAT 5 is 100 MHz with data transfer at speeds up to 1000 Mbps. CAT 6 is 250 MHz and can get up to 1 Gbps. Cat7 ups the ante substantially with 600 MHz and 10 Gbps rates.
  • Which cat cable is best?

    Cat 7a is the newest, best, and priciest ethernet cable on the market. Similar to the Cat 6a and Cat 7 cables, the Cat 7a supports speeds up to 10,000 Mbps, but its max bandwidth is exponentially higher at 1,000 MHz.
  • Is there a Cat8 cable?

    CAT 8. Category 8 is the official successor to Cat6A cabling. It is officially recognized by the IEEE and EIA and parts and pieces are standardized across manufacturers. The primary benefit of Cat8 cabling is faster throughput over short distances: 40 Gbps up to 78' and 25 Gbps up to 100'.
  • Can I plug a Cat8 cable into a Cat6 jack?

    One of the great things about Cat8 cable is the backward compatibility it provides. Just like Cat5e, Cat6, Cat6a, and Cat7 cabling, Cat8 Ethernet Cable uses RJ45 connectors making it fully backward compatible.
  • CAT 5 VS. CAT 6

    Though each has varying performance capabilities, both use the same RJ-45 end to connect to computers, servers, routers, or other devices. Due to their different capabilities, Cat 5 and Cat 6 support different parts of an overall network system. Their higher capacity balanced with their short range and higher cost make Cat 6 cables the ideal choice for network backbones, but Cat 5 or Cat 5e cables tend to be the preferred choice for runs to individual workstations.
  • How can I choose the right Cat cable?

    First, determine the speed of your internet connection. An old ethernet cable cannot be able to sustain you if you have internet running on a gigabit. But if you have a slower connection, like 10 or 20 megabits per second, you can get Cat 5.
    Next, consider the speed you need for your network. If you happen to move files frequently or you video stream most of the time, a high bandwidth is required so a better Cat cable can be better.
    Finally, consider your router. A Cat 6 or newer is usually used as routers rarely support more than gigabit Ethernet, but some may use Cat 5e.
