What is Bulk Cable?

Bulk cables are the most suitable cabling solutions where customizable lengths and specific cable distances are needed. In building constructions, movie theaters, auditoriums, and many more, they are usually the routed cables that are in permanent installations behind the walls or above the ceilings. These are usually cables that are buried deep into the wall, floorboards or ceilings so they require a specific amount of strength, rigidity and durability that can withstand harsh conditions such as dirt, vibration, moisture, and abrasion.

OTSCABLE the best bulk cables in the market with twisted pair wires that fits standards and provide greater bandwidth with minimized crosstalk. We offer networking and coaxial bulk cable up to 1000 ft (305 m), easy to use cable dispensers and tools, connectors and plugs, and cable management hardware ready for use in the field.

OSTCABLE Bulk Cable Manufacturing Process

With our company’s expertise in cable production, our in-house cable manufacturing process produces the best premium Bulk Cables

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

1st Wire Draw

The first step in manufacturing bulk cables 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 the 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 result of this process is a 5000 ft of coil of 10, 12, or 14 AWG copper wire.

2nd Wire Draw

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.

In the second wire draw, the size of the wire is reduced to 19, 22, 24, 26AWG or to any size needed.

Step #2: Annealing Softens the Wire

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 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, Insulation, and Testing

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 melts.

Step #4: Wire Diameter and Insulation Testing

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

The wires that came out from the stranding process are grouped together forming a multi-unit cable core. A rotating core truck twist together the cables that provides protection against electrical interference and provides flexibility.

Step #7: Jacketing

At jacketing, several operations such as gel-filling, armoring, jacketing, and printing are performed to produce the finished cable. Upon finishing the jacketing operation, the finished cable is wound onto wooden reels.

Gel-filling and Armoring

The cable core is heated ensuring that the filling compound penetrates possible voids. A filling compound is added into 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 cables.

Extrusion of Outer Cable Jacket

Extrusion again takes place for the outer cable jacket. It is usually made from low-density polyethylene, is colored black and can has a characteristic of being ultraviolet light resistive in case it is exposed to sunlight. This rugged thermoplastic is the final protective layer applied into the group of conductors enclosing the against the environmental conditions.


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. The cable labels are stamped into the jacket itself and will be permanently marked for its lifetime.

Step #8: Cables Tested Before Shipping

After the jacketing operation, the cable is wound onto wooden or metal reels. Then it is transported to the final test facility.

Physical Inspection of the Bulk Cable

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

Fluke and 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 done to check the conductor’s electrical integrity. Tests will be performed for mutual capacitance, unbalance, and resistance.


Before cable shipment, the cable ends are sealed with a steel or plastic cap, and testing air-core cables. Such cables are equipped with valves so that dry, pressurized air can be pumped into them to protect them from moisture.

Bulk Cable Standard Packaging Specifications

For bulk orders, we have the standard 1000 feet(305 m) per reel weighing about 11 kg. A carton contains 2 rolls. We also have cable spools of about 100m, 500m, and 1000m that you can choose from.


Quality Control

“If a thing’s worth doing, it’s worth doing well,” as quoted by a Chinese proverb.

OTSCABLE not only assures the best quality Bulk Cables are delivered into the market but also upholds an environmental responsibility of disposing of raw materials, in-process products, and end-products which can potentially harm the environment.

OTSCABLE follows a round of quality checks throughout the production process from raw material acceptance to production and to end-products processing prior to shipping.

Raw-Material Quality Control (RMQC)

High-quality raw material is paramount in delivering standard-wise end-products. Upon delivery of the raw materials (copper wires, etc), they go through IDC inspection that determines whether they pass or fail. Failure to meet specific standards will automatically reject the raw materials.

Production Quality Control (PQC)

Mass producing bulk cables from the raw materials stored in the warehouse is carried out in the production area.

Fluke testing is done to test for on-contact to contact voltage, continuity detection, and open jaw current detection. Also, the connectors are checked if they conform with T568B standard.

OTSCABLE also carries out a series of quality checks in the production area whether daily, weekly, monthly or yearly. This is to check if certain measures should be done in their machines or manufacturing process should be improved or fixed to meet safety standards for both the process and their employees.

In-Process Quality Control (IPQC) and Unfinished Product Quality Control (uPQC)

These are checks that are carried out during mass production is completed. In-process materials would be strictly tested for identity, quality, strength, and purity as appropriate and approved or rejected by the quality control unit during the production process.

Quality Control Before Packing and Final Quality Control

Before LAN Cables are packed or boxed, the QC unit checks the products for possible cracks, breaks and cable connectivity. The cables are also physically inspected and tested (electrical tests are run).


CE Approved

Products with a CE marking indicates conformity with safety, health and environmental protection standards for products sold within the European Economic Area (EEA), however, this is also recognizable worldwide.


RoHS stands for Restriction of Hazardous Substances. A RoHS listed product means the product has passed qualifications preventing the use of banned hazardous materials electrical and electronic products. These materials are hazardous to the environment and cause pollution to landfills. Moreover, they are dangerous when exposed during manufacturing and recycling.


Underwriters Laboratories (UL) is a Nationally Recognized Testing Laboratory (NRTL) recognized by the Occupational Safety and Health Administration (OSHA). As an NRTL, UL devises, publishes, updates, and maintains minimal standards that certain types of products: magnetic components, electronics, plastics, potable water, and others.
