PNCT Cable

PNCT Cable
  • Cable Type: PNCT (Formerly 2PNCT)
  • Rating Voltage: 0.6/1kV
  • Standard: JIS C3327 / IEC 60502-1

PNCT cable , also called 2PNCT, is a type of cabtyre cable that has a stiff sheath. This type of cable is ideal for low voltage electrical equipment in fields, such as construction, farming, and mining. Cabtyre cables, in general, power electrical equipment.

The sheath is usually made of flame-retardant material, making it ideal for tough conditions. PNCT cables may have many different variations, although the base structure is the same in all that helps identify them as PNCT.

  • Conductor: The conductor is the main element that drives the current through the cable. The conductor makes the center of the core.
  • Tape: The core in the PNCT cable is made of the conductor and the tape. The tape covers the conductor and is the layer between the conductor and the insulation layer. Insulation: Insulation in PNCT cable is typically rubber. It encapsulates all the cores at its center. The insulation, together with other components, makes it highly flexible.
  • Filling: Filling is inserted between the cores, so it’s the center-most component of the PNCT cable.
  • Sheath: The sheath is the outermost layer of the cable and is a stiff but flexible sheet that covers the insulation layer. It’s often black in color.

PNCT Cable Buying Guide

The integrity of any structure or machine depends heavily on its wiring. The cables you use should be appropriate for the application. More importantly, they should be of high-quality as faulty, cheap cables can cause damage.

You’ll find PNCT cables in lots of portable electrical equipment. It’s similar to the cables we see at home on appliances such as refrigerators, air conditioning units, washing machines, and kitchen appliances. This is because they come from the same set of cables with similar features.

PNCT Cable Features

PNCT cables come in a variety of sizes, with the distinctive feature being the number of cores. They can have anywhere from single to up to eight cores.

Now, the number of cores in the cable depends on the application of the cable. The heavier the usage, the more cores will be needed. This will also determine the voltage the cable can support. The cores are typically colored differently, but there isn’t any specific standard about colors.

PNCT cables can typically support a voltage of 0.6/1kv, but you can find other voltages as well. Voltage is basically the work the cable does to push the current through the conducting loop. This also depends on the application of the cable, as heavy equipment will require more voltage.

Insulation in PNCT cables is typically not that thick, but in some cables, the insulation can be thicker. Similarly, the filling also varies by manufacturers. Some use a mix of talcum powder and calcium carbonate, while some use very fine calcium carbonate as filling between the cores.

PNCT Cable Applications

Cabtyre cables, in general, are used in electrical appliances and equipment. However, PNCT cable is mainly used in equipment used in the following industries:

  • Mining
  • Farming
  • Construction

Unlike the appliances or tools we use at home, these industries utilize heavy machinery, often in rough conditions and outside. So they need a very specific type of cable that can withstand those conditions and provide good voltage for the equipment.

Machines like excavators, drills, shuttle cars, ploughing machines, irrigation machinery, and power tills may use such cables.


The specifications of the PNCT cables varies by its subtype, but here is a typical 2PNCT wire’s specification:

  • Voltage: 0.6/1kV
  • Conductor: tinned or bare copper
  • of Cores: 1,2, 3, 4, 5, 6, 7, 8
  • Insulation: Rubber
  • Standard: JIS/IEC/VDE
  • Color: Black

Advantages of PNCT Cable

PNCT cables offer many benefits that are specifically important for applications in the fields above. Here are some of the advantages:


PNCT cables are extremely weather-proof. Made of a flame-retardant, chloroprene rubber, they can withstand mechanical and environmental pressure. They can withstand water, wind, moisture, heat, and chemicals (both acidic and alkaline).

This advantage alone makes them ideal for equipment and structures that are outdoors in tough conditions. For instance, mining may involve water and chemicals, so the cables will stay intact even in a very rough underground environment.

Pressure Resistance

PNCT cables are designed in such a way that they can handle mechanical pressure and friction. They will not break so easily, which makes them good for industries employing heavy machinery and equipment.


The sheath is firm but bendable, so the cables are flexible enough to be moved through curvy spaces. You can easily bend and twist the cable without damaging its core. This gives it a lot more versatility.

Long Life

The cable is surrounded by rubber which not only tolerates tough conditions but also lasts a lifetime. As compared with synthetic insulation, rubber is much stronger and durable. It’s also more lightweight, so PNCT cables are typically not that heavy.

What is the difference between PNCT-R and PNCT-F?

The main difference between PNCT-R and PNCT-F cables is the placement of the cores. In PNCT-R cables, the cores are located centrally with a single layer of filling in between all of the cores.

On the other hand, PNCT-F cables have cores side-by-side parallel to each other, forming a line. For this reason, PNCT-F cables are wider as the cores are not centralized rather distributed through the width of the cable. They don’t have any filling like PNCT-R cables.

Overall, both cables have the same construction and similar uses. PNCT-F offers more tension than PNCT-R cables. It’s used in applications such as unloader, stacker, and Gantry cranes.


PNCT cables are employed in many industries all over the world. They are known for their weather resistance and flexibility. The rubber insulation is what sets them apart, so ensure the ones you’re buying have rubber insulation.

Also, pay attention to how the cables are packaged. They should come in iron or wooden drums that can protect them in transit. If you’re unsure about the specifications and the type of PNCT cables you need, consult with an expert, and go with that.
