The PVC compound used for cable sheaths is generally very flexible, durable and long lasting making it a very popular choice. VDE Symbol. Voltage Search: 300V. MC cable: The original cable to both lighting and receptacles (totaling 4,320' of cable) needs to be removed (or abandoned in place) from the entire Category 2 space. Each jacket type has different benefits like washdown, abrasion resistant or high flexing applications. depending on their purpose, there’s a basic format that most cables follow. A cable jacket might need to hold up to relatively minor wear and tear applications. Ethylene Tetrafluoroethylene, ETFE Insulated/Jacketed Wire & Cable. These compounds are heated and extruded over conductor. If you have any questions about our cable or wire products, or if you’re looking for a quote, contact us at (800) 905-7161 or through our online form. All of the materials that General Reliance offers for their cable assemblies have specific applications and properties. applications for the common jacket materials used in certain OCC fiber optic cable products. PVC -- Polyvinyl chloride (vinyl), a general-purpose plastic jacket material used for cables. 1. The outer jacket of a cable protects against mechanical stress, high temperatures and chemical substances, among many other conditions. LDPE (Low Density Polyethylene) has the most exc… PUR (Polyurethane) – Elastic, abrasion-resistant, low-temp flexibility, oil-resistant. A third mechanical test, measuring compressive modulus, involves checking the ductility of the cable insulation or jacket material to determine if the cable has become dry, brittle, or prone to crack. These are the only plastics that have a lower specific gravity than water. Normally less expensive 3. No cure required 4. THERMOPLASTIC: A material which will soften, flow, or distort when subjected to sufficient heat and pressure. Thermoplastic vs. Thermoset Wire and Cable Materials One of the most beneficial ways of distinguishing the characteristics of a wire or cable is to determine if the insulation or jacket material used is a thermoset or a thermoplastic. SJEOW), only the outer jacket material is oil resistant. (Pricing valid in US only) It’s important to consider the jacket type when selecting the compatibility with the application’s connectors and environment. PVC is by far the most common type of cable sheath and is ideal for general use cables. Thermoset polyolefins are a common electric cable casing in welding because they can withstand direct heat without melting. This quick cable jacket material comparison will breakdown the pros and cons of each material. This material is used primarily as a cable jacket material. Jacketing is a cable’s first line of defense. A Thermoplastic is a material that softens when heated and becomes firm when cooled. This material is primarily used as an insulation material. CABLE JACKET TYPES. Materials of the jacket is either the low-smoke polyvinyl chloride (PVC) or the fluorinated ethylene polymer (FEP). Your design looks great on paper. Industries We Serve. View Details. Hytrel®, Teflon® and Tefzel® are a registered trademarks of E. I. du Pont de Nemours and Company. Fiber cable jacket is made of various types of materials. Cables jackets are designed to protect cables and cords in specific environmental challenges. MC cables come in a variety of configurations including isolated grounds, neutral per phase, super neutral and home run cable. Click here to see an Insulation & Jacketing Materials Comparison Chart. Wire & Cable Insulation & Jacket Materials. They are not recommended for uses which require flexing at temperatures below -40° C. Polyethylene is the most moisture resistant of the jacketing materials, and is used almost exclusively for direct burial cables. This makes it suitable for thin wall insulations. In the latest edition of Northwire’s eCURRENT newsletter, the authors explain that users should consider several parameters before selecting a jacket material for a cable. Here’s how to know what ones to choose from. Below is a table with the common cable materials and their related properties. Polyvinyl Chloride (PVC) – Cost effective, flame retardant, temperature range -20 to +80 C. Environmental resistance good, chemical resistance poor, marginally flexible.
