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.

What is wire jacketing?
As mentioned above, the jacket is the exterior layer that pulls the interior components together. Proper wire jacketing protects the cable components from the outside environment which can damage or deteriorate the conductors, insulation, or shielding.
What is a cable jacket 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.
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.
What is PVC jacket on cable?
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 XLPE cable?
1.2.1 Description of XLPE cable
XLPE is an acronym for cross linked polyethylene. XLPE is a thermosetting polymer meaning that the material (polyethylene (PE)) is cured under heat and in that process forms bonds in all directions forming a three dimensional matrix.
How are cable jackets made?
Depending on the type of cable being constructed, strands are then collated and insulated together with a LDPE (low density polyethylene) cover. An outer PVC jacket is molded around them. The PVC jacket is formed very quickly by the extrusion machine, and applied over a layer of HDPE insulation.
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
Is PVC cable jacket UV resistant?
PVC has a good combination of characteristics that explain why it is so commonly used for wire insulation and cable jacketing. PVC is durable, UV resistant and exhibits good resistance to chemicals and water.
Why is it called coaxial cable?
Coaxial cable received its name because it includes one physical channel that carries the signal surrounded — after a layer of insulation — by another concentric physical channel, both running along the same axis. The outer channel serves as a ground.
Why is coaxial cable used?
Coaxial cable is used as a transmission line for radio frequency signals. Its applications include feedlines connecting radio transmitters and receivers to their antennas, computer network (e.g., Ethernet) connections, digital audio (S/PDIF), and distribution of cable television signals.
What are the 3 types of wires?
Three types of wire used are :
- live wire ( Red colour)
- neutral wire(Black colour)
- earth wire (Green colour)
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 does CL3 rated mean?
In plain English that means that CL2 and CL3 are rating types for most types of low voltage cabling such as: speaker wire, Cat5/6, and HDMI cables. The difference between the two is that CL2 is rated for up to 150 volts while CL3 is rated for up to 300 volts.
What is XLPE insulation?
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.
What is TPU cable jacket?
Thermoplastic polyurethane (TPU) is the most durable of materials commonly used to jacket medical cable. It has excellent abrasion resistance, tensile strength and high tear resistance. And, while it is available in softer grades, it is typically not as flexible as the three previously listed materials.
What is EPDM jacket?
What Is EPDM Cable? These cables use ethylene propylene diene monomer (EPDM), a type of rubber, as a jacket surrounding the wires. This cross-linked elastomer offers strong flexibility, durability and moisture resistance.
Which is better XLPE or PVC?
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. PVC insulation cannot withstand as much pressure, meaning it is only suitable for low tension applications.
Is XLPE waterproof?
In order to prevent the penetration of moisture and also to extend the duration of life, the XLPE insulated medium voltage cables are designed with longitudinally waterproof shielding including an additional swell tape and PE outer jacket.
What is FRLS cable?
FRLS Cable means Flame Retardant Low Smoke. These cables are fire resistant which are used at the locations that are more prone to fire. Flame Retardant Low Smoke PVC compound which is present in the cable, makes sure the release of low smoke compared to other wires with PVC coating.
