Polyvinyl chloride (PVC) wire is a single or multi core PVC insulated wire. In most instances, the wire has no jacket except when it has more than one core. PVC is a thermoplastic material that softens with heat, a factor that eases wire production and allows manufacturers to extrude the PVC cable insulation.

What are PVC cables used for?
PVC wires and cables are commonly used for home appliances, wiring of circuits, instruments, house wiring, mining operations, power supply solutions, submarines, ship wiring, etc. they’re even used in high temperature-sensitive environments like kitchen and related appliances.
What is XLPE and PVC cable?
XLPE, as explained above, is cross-linked polyethylene material. PVC stands for polyvinyl chloride insulation. The main difference between the two is that XLPE can be used for both high and low tension applications. Its structure provides great resistance to abrasion, stress, and other wear and tear.
Is PVC cable safe?
A safe choice…
PVC has a low ignitability, low flammability and does not generate flaming droplets. As a result, wires and cables made with PVC insulation or sheathing are fire-resistant, self-extinguishing and produce moderate heat in the event of a house fire.
What type of PVC is used for wires?
1. SAB-special PVC (Y) – characteristics and advantages. Our special PVC (YA and YM) are used for insulation and sheathing purposes. PVC type YA is used for core insulation and is particularly flexible and has very good electrical characteristics.
What does PVC stand for?
Definition of polyvinyl chloride
: a polymer of vinyl chloride used especially for electrical insulation, films, and pipes —abbreviation PVC.
What are the disadvantages of PVC?
What are the Disadvantages of Polyvinyl Chloride?
- Polyvinyl Chloride has very poor heat stability. For this reason, additives that stabilize the material at higher temperatures are typically added to the material during production.
- Polyvinyl Chloride emits toxic fumes when melted or subject to a fire.
Which is better XLPE or PVC?
Water Proof Performance in Application Environment: PVC insulated cable is better than the XLPE insulated cable. Environment Protection aspect: For XLPE is not containing chlorine which will release toxic gases once burn, so XLPE insulated Cable is environment friendly compared with PVC insulated Cable.
What XLPE means?
Cross-linked polyethylene
XLPE or Cross-linked polyethylene is a thermoset insulation material. Crosslinking polymers is a process which changes the molecular structure of the polymer chains so that they are more tightly bound together and this crosslinking is done either by chemical means or physical means.
Where is XLPE cable used?
Common applications of cross-linked polyethylene (XLPE) are in building plumbing (or pipework) systems, as insulation for high voltage cables, and as an alternative for polyvinyl chloride (PVC) and copper tubing in water pipes.
Are PVC cables waterproof?
Well, PVC is primarily water-resistant, but it largely depends on how much time it stays in the water. For instance, PVC jacketed cable can come in contact with water and quickly dry out without any harm. However, if you intend to an underwater installation, you shouldn’t use an ordinary PVC cable.
What are the disadvantages of PVC conduit?
Disadvantages of PVC conduit include its physical weakness compared to metal. PVC can break and splinter when exposed to physical stress. It also needs to be supported when installed in longer runs due to sagging. You can bend PVC conduit cold (ambient temperature of 15.5 C) up to about 25mm.
Is PVC cable flexible?
PVC cable is not as flexible as silicone cable. This can be an important factor when cabling is in enclosed and poorly accessible locations.
How are PVC cables made?
PVC Cables Manufacturing Process
Copper conductor (wire) of the required size is fed into the Extruder wherein PVC is coated on the wire to the specified thickness. The extruded wire after passing through the cooling tank is coiled on the take-off system.
What are the types of PVC?
PVC pipes are generally categorised into four: PVC-U unplasticised PVC), C-PVC (chlorinated PVC), PVC-O (molecular oriented PVC) and modified PVC.
About PVC-HI
- a mixture based on PVC.
- a blend based on PVC.
- a copolymer based on PVC.
- a combination of these types.
What is PVC made of?
The basic raw materials for PVC are derived from salt and oil. Chlorine is manufactured by the electrolysis of sodium chloride, salt. This is why the first PVC manufacturing plants were located close to natural sources of salt. The electrolysis of salt water produces chlorine.
Is PVC A plastic?
Over the past few decades, Polyvinyl Chloride (PVC) plastic, commonly known as “vinyl,” has become one of the most widely-used types of plastics. We find it all around us: in packaging, home furnishings, children’s toys, automobile parts, building materials, hospital supplies, and hundreds of other products.
How strong is PVC?
PVC-U (unplasticised) is hard and rigid with an ultimate tensile stress of approximately 52 MPa at 20°C and is resistant to most chemicals.
What are the pros and cons of PVC?
PVC Pros. Usability: PVC is durable and usable for a variety of purposes. In many cases, its sturdiness makes installation much easier and it can be used in a wide range of environments, whether in ceilings, walls, or floors. However, the difference in weight can be an issue (more on that in the cons).
How do I know if I have PVC or XLPE cable?
So let’s see the differences in the following aspects:
- Maximum working temperature of conductor: PVC insulated Cable is 70 Centigrade, XLPE insulated Cable is 90 Centigrade.
- Maximum short (lasting less than 5 seconds) temperature: PVC insulated Cable is 160 Centigrade, XLPE insulated Cable is 250 Centigrade.
How do I know if my cable is XLPE?
You can usually tell by looking at the bedding around the insulation. XLPE has a softer, peelable appearance.
