Cable jackets are most frequently made out of poly(vinyl chloride), polyethylene, chlorinated polyethylene, and chlorosulfonated polyethylene/neoprene.

What is cable jacket?
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 the most flexible cable jacket material?
PVC Polyvinyl Chloride (PVC)
PVC. 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.
What is TPE cable jacket?
TPE is a thermoplastic elastomer material. TPE-U is commonly used for flexible cables, as it can reliably withstand mechanical loads and has resistance to external influences such as chemicals and extreme temperatures. TPE is generally suitable for a temperature range of -31˚ to 212˚F.
What is LDPE jacket?
Types of Cable Jackets
Excellent electrical properties with very high insulation resistance. Polyethylene can be stiff and very hard, however low density PE (LDPE) is more flexible. Moisture resistance is excellent.
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 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.
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.
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 cable insulator?
Insulated wire or cable consists of a non-conductive material resistant to an electric current. It surrounds and protects the wire or cable inside.
Is TPE better than PVC?
It’s PVC’s flexibility and high mechanical strength that makes it a popular choice for caps and plugs. Like PVC, TPE is also versatile.
| Resistance | PVC | TPE |
|---|---|---|
| Low-temperature flexibility | Poor – good | Best |
| Weather, including sun | Good – excellent | Best |
| Ozone | Excellent | Excellent |
| Abrasion | Fair – good | Excellent |
What is TPU and TPE?
TPE and TPU are thermoplastic elastomers, or rubber-like materials. They have been around since the 1950’s. TPE’s and TPU’s are used to make rubber-like cases, lids, panels, soles for footware, etc. Recently both materials became available as 3D printable materials for the additive manufacturing industry.
What is TPE made of?
Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties.
What is HDPE cable?
High-density polyethylene (HDPE) conduit is the preferred material to house and protect electrical power and telecommunications cables within. It offers unmatched corrosion and chemical resistance, is flexible, durable and available in long reel lengths to reduce joints and installation time.
What is CPE cable jacket?
CPE – Chlorinated Polyethylene (CPE) is one of the few polymers that is available as both a thermoplastic and a thermoset jacket (thermoset CPE would be a cross-linked version). The thermoplastic CPE jacket has excellent oxidation, heat, oil, weather/sun and flame resistance.
Is HDPE the same as PVC?
PVC is a durable vinyl polymer whereas HDPE is a polyethylene thermoplastic made from petroleum. Both pipes are strong through high temperatures. When comparing failure ratings when exposed to events like rain, stress, wind, heat or cold, HDPE is proven to be more durable.
What is the material of the cable?
Wire and Cable Conductor Materials
They are mostly made of metal due to metal’s high conductivity. Some metals, however, are more conductive than others. Aluminum, copper, and high-strength alloys are the main materials you’ll find at the center of your wire and cable.
Does cable wire have copper in it?
Computer Wire – Most wires from computers and power cables from computers are low copper content which is why we named the category computer wire. This category also has many other types of wire in it because of the percentage of copper this category is for insulated wire with a copper content of around 30 -37%.
What are wires covered with?
Electrical wires are usually covered with insulating materials, such as plastic, rubber-like polymers, or varnish.
How can you tell if a cable is PVC?
Look at the packaging. Formal PVC insulated cable packaging will be printed with the manufacturer, address, inspection seal and production date. If not, most of them are inferior products. II.
How do you tell if cable is UV rated?
The information printed on a cable jacket will usually tell you everything you need to know. Typically this includes the manufacturer or UPC code, jacket material, any electrical standards it meets, temperature rating, and frequently a material rating that will tell you where the cable can be run in a building.
