A jacket is an outer sheath that protects the wire or cable core from mechanical, moisture and chemical issues.
In this post
What is the purpose of 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 purpose of the jacket on medium voltage cable?
Cable jackets protect the conductor core and insulation of cable assemblies from environmental damage.
What is a cable sheath?
Insulation and sheath are the components of a cable that protect the conductor. The insulation isolates the flow of electricity, and the sheath wraps around the outside of the cable to protect the conductors inside.
What is the material on cable jacket?
Polyvinyl Chloride (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. 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 does a jacketed wire mean?
A jacket is an outer sheath that protects the wire or cable core from mechanical, moisture and chemical issues. Jackets help with flame resistance, protect against sunlight and facilitate installation.
What is general purpose cable?
The General purpose I/O cable is 16 conductors, multicolor flat ribbon cable. It is connected using a 16 pin TE Connectivity Micro-match connector. The cable is left open on one side so that it can be connected to customer-specific connectors.
What is an outer jacket?
n. 1. an outer garment with sleeves, covering at least the upper part of the body. 2. a natural integument or covering, as the hair, fur, or wool of an animal, the bark of a tree, or the skin of a fruit.
Is a jacket an insulator?
An interesting application of insulators is if you wear a jacket when it is cold out. The jacket doesn’t actually provide any heat the way a radiator does, but what it does do is that is slows down the rate at which heat leaves your body into the air.
What is CPE jacket cable?
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.
Why lead sheath is used in cable?
A Lead Sheath is available on many types of wire and cable insulations. This sheath is completely moisture proof and very durable. Where both mechanical strength and moisture resistance are required, a combination of Lead sheath and armor can be used.
What is mainly used for cable sheathing?
PVC Cable. Polyvinyl Chloride (PVC)s is the most common sheath type. It’s low cost, easy to make, and is found on most cables unless a specific requirement for another sheath type exists.
What is inner sheath in cable?
Purpose: It could be also called inner sheath or inner jacket, which serves as a bedding under cable armoring to protect the laid up cores and as a separation sheath. Inner sheath is over laid up of cores. It gives Circular Shape of the cable and it also provides Bedding for the armoring.
What information must be printed on the cable sheath?
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.
Does plenum mean shielded?
Plenum rated cables can help prevent the spread of fires, but keep in mind that a Plenum rated cable will have no data transmission speed benefit over a non-plenum rated cable. This cable is shielded for use in heavy electronic environments.
What does SJTW mean on an extension cord?
Junior Hard Service Thermoplastic
Thermoplastic (PVC) insulated conductors and jacket. Indoor use; tools and equipment, lights, power extensions. SJTW. Junior Hard Service Thermoplastic, Outdoor Rated. Moisture- and sunlight-resistant thermoplastic (PVC) insulated conductors and jacket.
How do you protect electrical wires?
How To Protect Electric Wire?
- Reinforced Plastic Bindings. These are used to group cables so they don’t entangle with one another and are a good start at protecting them from light damage.
- Braided Sleeving.
- Cable Ducts.
- Plastic Conduits.
What does 2 conductor wire mean?
The second the number of current carrying conductors in the wire – but remember there’s usually an extra ground wire. “12-2” means 12 gauge, two insulated current carrying wires, plus a bare ground. 12-2 wire usually has a black, white and bare ground wire.
What is a riser tube?
Definitions of riser pipe. a vertical pipe in a building. synonyms: riser, riser main, riser pipeline. type of: pipage, pipe, piping. a long tube made of metal or plastic that is used to carry water or oil or gas etc.
What is CL2 wire?
CL2: This is a cable jacket fire resistance rating defined in Article 725 of the National Electric Code. It stands for “Class 2 Remote-Control, Signaling, and Power-Limited Circuits” cable, which indicates that the cable is suitable for in-wall installation and use for certain low-voltage applications.
What increases the flexibility of a wire?
Most industrial wire is made up of multiple wire strands, called ‘base strands’, rather than being made of a solid piece of metal. Multiple strands make the wire more flexible, allowing it to bend and flex more easily than solid metal. The finer the base strand, the more flexible the wire.
