Polyvinyl Chloride (PVC) is the most common jacket material used in cabling today. PVC is a cost-effective option yet still flexible and rugged enough for many work sites. Depending on the formulation, a PVC jacket can be weather and oil resistant as well, offering a wide variety of use cases and application variety.

What is the jacket on a cable?
What is a Cable Jacket? A jacket is the outermost layer of a cable whose primary function is to protect the insulation and conductor core from external physical forces and chemical deterioration. In a sense, the cable jacket is the first line of mechanical defense for a cable by protecting its inner components.
Which cable is provided with PVC jacket around it?
PVC is used for hook-up wire in many UL styles; the most common are UL1007, UL1015, UL1060, and UL1061. PVC is used for hook-up wire in many MIL-SPEC styles; the most common are M16878/1, M16878/2, and M16878/3. PVC is used for multi-conductor cable in many UL styles; the most common are UL2464 and UL2586.
What is the jacket of a wire made of?
Cable jackets are most frequently made out of poly(vinyl chloride), polyethylene, chlorinated polyethylene, and chlorosulfonated polyethylene/neoprene.
What is coaxial cable jacket?
The cable jacket is the first line of moisture, mechanical, flame and chemical defense for a cable. More specifically, the jacket provides protection for the shielding and conductors within the cable. The jacket protects the cable from mechanical damage during and after installation.
Is PVC cable jacket waterproof?
It may be that when you read the title of this blog, “Waterblocking” that you thought to yourself, “Isn’t ALL jacketed wire and cable waterproof?” The answer is “No.” Almost every jacket compound, from PVC to Polyethylene to Teflon® is at least water resistant, so they can get wet and then dry out and they cables would
What is the jacket of a fiber optic cable?
As the bare fiber is easily broken, fiber optic cable jacket is needed to provide protection for the shielding and conductors within the cable. The cable jacket is the first line of moisture, mechanical, flame and chemical defense for a fiber cable.
What is PVC cable insulation?
Cable with a PVC insulation or sheathing is flame retardant, which is an important consideration for electric cables in most applications. PVC can be made resistant to a wide range of chemicals including oils, acids and alkalis, and is tough, durable and resistant to abrasion.
Is PVC jacket outdoor rated?
Temperature Rating
Standard PVC cables can only withstand a temperature down to -20°, whereas outdoor rated cables use a PE (Polyethylene) jacket that can withstand temperatures down to -40°C. A cable with an outdoor-rated PE (Polyethylene) jacket is recommended for cables that are going to be used in colder climates.
What jacket material is used for corrosion resistant cables?
The three main sensor cable jackets are PVC (Polyvinyl Chloride), PUR (polyurethane) and TPE (thermoplastic elastomer).
Which insulation is used in cables?
The various insulating materials used in manufacturing of cables are rubber, VIR, paper, Polyvinyl Chloride (PVC), Varnished Cambric, Polyethylene, Gutta-Percha, Silk, Cotton, enamel etc.
Are cable jackets waterproof?
It may be that when you read the title of this blog, “Waterblocking” that you thought to yourself, “Isn’t ALL jacketed wire and cable waterproof?” The answer is “No.” Almost every jacket compound, from PVC to Polyethylene to Teflon® is at least water resistant, so they can get wet and then dry out and they cables would
How do you read a cable jacket?
The two-digit number listed next to the number of pairs provides the American wire gauge—or the cross-sectional area of a round wire (essentially the diameter). The larger the number, the smaller the cable’s overall diameter. In this case, a 23 AWG cable diameter is pretty small (0.25 in) so it’s easier to manage.
Is PVC cable UV resistant?
The most common sheath material used in cables is PVC. This is one of the most inherently UV resistant polymers available. It is regarded as “Very Good” in resistance to UV (not “Excellent”).
Why PVC is used in wire cable application?
PVC wire and cable are where a thermoplastic material called Polyvinyl Chloride also referred to as PVC is used for wire insulation or cable jackets. PVC wires and cables are widely used due to excellent properties such as chemical, heat and water resistance, robustness, durability, and versatility.
Is PVC insulating?
PVC has excellent electrical insulating properties, making it a primary choice for electric cables for residential buildings, vehicles etc.
What does OFNR stand for?
Optical fiber, nonconductive, riser
Optical fiber, nonconductive, riser (OFNR) is a type of optical fiber cable.
What is buffer coating?
Buffer (buffer coating) A protective layer or tube applied to a fiber-optic strand. This layer of material, usually thermoplastic or acrylic polymer, is applied in addition to the optical-fiber coating, which provides protection from stress and handling.
What does cladding do in optical Fibres?
Cladding in optical fibers is one or more layers of materials of lower refractive index, in intimate contact with a core material of higher refractive index. The cladding causes light to be confined to the core of the fiber by total internal reflection at the boundary between the two.
What does PVC stand for?
Definition of polyvinyl chloride
: a polymer of vinyl chloride used especially for electrical insulation, films, and pipes —abbreviation PVC.
Is PVC a good thermal insulator?
PVC is a good insulator.
