Many of the handheld thermal strippers have adjustable wire stops to multiple wires have the same strip length (Figure 4). TEFLON (FEP)is extrudable in a manner similar to PVC and polyethylene, allowing for long wire and cable lengths. Give a gentle pull on both sides of the insulation to break the thin film of insulation still connecting the insulation slug from the insulation (Figure 8). The best way to maintain the natural lay of the strands is to slowly twist in the direction of the strand twist as you are pulling the insulation slug from the wire. Its dielectric constant and dissipation factor at 1 Mhz are 2.6 and 0.013 respectively. Can be cross-linked either chemically or irradiated. Sometimes designated asXLPE. Figure 9. They are resistant to environmental hazards and corrosion. | Lazada, Browse Alphabetically: - PFA is a registered trademark of DuPont Corporation.

CSPE has excellent tear and impact strength, excellent abrasion, ozone, oil, and chemical resistance and good weathering properties. Thermoplastic compounds use additives to strengthen specific properties of thermoplastic. Subscribers will always find in-depth coverage of industry events pertinent to these industries. SEMI-BUTYL RUBBER(SBR)is flexible and offers good heat and moisture resistance at an economical cost. - There are many different factors that play into choosing wire and cable, including the type of wire insulation. In terms of flexibility, polyethylene can range from stiff to very hard depending on molecular weight and density. The dielectric constant is 2.3 for solid insulation and 1.5 for cellular (foamed) designs. These additives have only a slight effect on physical or electrical properties of the insulation. Tefzel can withstand an unusual amount of physical abuse and is self-extinguishing. Industrial Ethernet vs. It is also highly moisture resistant. This online shopping platform has partnered with various global wholesalers to offer you a wide range of connectors. RULANis a flame retardant polyethylene which contains additives to inhibit the rate of burning. through the insulation, and with normal pressure applied, it will leave a very thin film of insulation between the blades and the wire strands. Wire insulation is the material that covers and holds together the wires. Wire preparation is the first step in the process and wire insulation removal (stripping) is the first step in wire preparation. KYNARhas great mechanical strength, superior resistance to abrasion and cut-through and substantially reduced cold-flow which makes it an excellent back plane wire insulation. Read on below to learn more, or Search our catalog to find the right wire for your next product or project. Are you looking for a wholesale thermal wire sleeve? IRRADIATED PVChas improved resistance to abrasion, cut-through, soldering and solvents. Since 1994, Wiring Harness News has been the pioneer voice for decision makers in engineering, procurement, and top management for manufacturers of critical wiring systems. The quarter turn will ensure that there is no area of the insulation that did not make contact with the heated blades. With no physical contact between the blades and the wire strands, strand damage from the stripping operation is avoided. They also maintain their shape better in colder environments. Silicone typically has low mechanical strength and poor scuff resistance. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. - User Information Legal Enquiry Guide, 1999-2022 Alibaba.com. POLYVINYL CHLORIDE PVC, sometimes referred to as vinyl or polyvinyl chloride, consists of three types of vinyl compounds - standard, semi-rigid and irradiated. Kynar is self-extinguishing, radiant resistant and rated at 135C. EPR has temperature ratings up to 150C.

Mechanical Stripper (Figure 2, to be covered in the next issue), Thermal strippers usually come in a hot tweezer configuration with various styles of opposing elements (Figure 3). We will focus on manual insulation stripping using one of the two most common tools for manual stripping. Irradiated products can be extruded in smaller sizes. UL maximum temperature ratings may be 60C or 105C. When the strands are overtwisted (Figure 10) it may result in diminished long term reliability and may also affect the electrical characteristics of the wire. It must be jacketed for mechanical and chemical protection. Onetouch Its temperature rating is -70C to 150C. Thermal strippers have one major advantage over other types of handheld wire stripping devices. When the strands have been straightened out during the insulation removal, birdcaging of the wire strands is likely to occur (Figure 9) resulting in diminished long term reliability. What is wire insulation, and why is it important? This material also has low moisture absorption, excellent resistance to flame and heat, and good dielectric properties. Need Help? Depending on the project that you are working on, you may want to choose a wire insulation that specifically uses one of the following thermoplastic compounds to better serve your needs. Like many conventional rubber materials, TPR is highly resistant to oils, chemicals, ozone and other environmental factors.
