Hvordan velge de riktige kabelbåndene for ledningsnettet?

Følgende er en omfattende veiledning for valg av buntebånd:
jeg. Materialvalg
‌Nylon materiale: Generelt egnet for miljøer mellom -40 ℃ og 85 ℃, med korrosjonsbestandighet, selvlåsende og isolasjon. For områder med høye temperaturer som motorrommet, du må velge nylonkabelbånd som inneholder varmebestandige komponenter (temperaturmotstand opp til 105 ℃)‌.
ingeniørplast: Slik som Wintone Z63-materiale, med høyere stivhet, lav vannabsorpsjon og kjemisk korrosjonsbestandighet, egnet for komplekse arbeidsforhold‌.
Materiale i rustfritt stål: Egnet for scener som trenger å motstå høyere temperaturer (slik som >105℃) eller svært korrosive miljøer.

UV-bestandig nylon: Egnet for utendørs bruk eller områder utsatt for sollys.
Lengde og Bredde:
Mål diameteren på bunten som skal knytes og velg et bånd som er langt nok til å vikle rundt bunten med litt ekstra lengde for å tre gjennom låsemekanismen.
Bredere bånd har generelt høyere strekkfasthet, gjør dem egnet for tyngre last eller større bunter.

Ii. Spesifikasjoner
Lengde og bredde
Enkelt ledningsnettfeste: velg 4×150-spesifikasjonen‌;
2-3 ledningsnett: velg 8×175-spesifikasjonen‌;
Flere ledningsnett: 8×240 spesifikasjon er foretrukket, og 10×400-spesifikasjonen brukes for midlertidig fiksering når det er utilstrekkelig‌;
Avstandskontroll
Festeavstanden mellom chassisets ledningsnett anbefales å være 300-400 mm for å unngå henging eller svaiing‌;

Through the comprehensive consideration of the above dimensions, sikkerhet, economy and maintenance convenience can be balanced to achieve reliable fixation of the harness system.

With the increasing use of electrical and electronic components and subsystems, properly securing cables is an important aspect of system design that is often overlooked. Whether within equipment or between systems, ensuring that cables are routed safely, securely and efficiently is critical to the success and longevity of a design, especially in high-vibration and harsh-environment applications. This article’s wiring harness engineer mainly introduces how to select and apply the correct cable ties for wiring harnesses.
The challenge for designers is to find cable ties that meet application needs in terms of tensile strength, longevity, fleksibilitet, chemical, vibration and ultraviolet (UV) radiation resistance. without over-engineering or compromising the integrity of the cable’s insulation and internal structure. This requires analyzing the many types of cable ties and various materials now available and differentiating them, fearing that choosing the wrong cable tie could end up costing much more than the purchase.
To alleviate these concerns, designers need to understand the nuances of cable ties and how to align their selection with application requirements. This article will outline the considerations for cable ties, the advantages of each type, and how to apply them effectively using real-life examples from Panduit Corporation.

Tie specifications
Cable ties, often called zip-ties or tie wraps, are available in a variety of lengths, widths, materialer, and colors. When bundling a wire bundle, the tie or tape portion should be wrapped around the wire bundle, pulling the loose end completely through the locking mechanism and tightening until the strap locking notch is securely engaged (Figur 1).

Figur 1: A typical cable tie showing the main components used to secure a cable bundle.
The cable tie may be constructed as a single piece with the locking barbs molded as part of the locking mechanism. In contrast, higher quality ties have a two-piece construction. In the two-piece design, corrosion-resistant stainless steel barbs are embedded into the lock head to grip the relatively smooth lacing surface. It is designed to provide a secure lock that is infinitely adjustable, as the barbs do not need to fit into the locking grooves.
The maximum diameter specification indicates the largest diameter wire bundle that the tie can accommodate. The bundling should be securely fastened without over-tightening and cutting or abrading the cable insulation. The length of tie used should allow for an extra point to engage the loose end in the locking mechanism.
The strength of a wrap is defined as the loop tensile strength (LTS) measured in pounds. LTS is the maximum force that can be exerted when the locking mechanism is engaged. The most common ties are between 18 pounds and 250 pounds.
LTS depends on the size of the tie and the material used. Material selection is primarily influenced by the environmental operating conditions the tie will experience. Considerations include:
Is it for internal or external use?
What is the expected temperature range?
Will it be exposed to water, olje, chemicals or vibration?
For eksempel, Panduit’s PLT1.5M-M10 cable ties are part of the company’s PAN-TY@PLT series of ties. This line of cable ties is its largest and most comprehensive range, offering ties in a variety of colors, materials and construction types. The PLT1.M-M10 has a nominal length of 5.6 inches (inches), a rated maximum diameter of 1.25 inches, and a tensile strength of 18 pounds. Frenulas are classified by their cross-sectional area as extra-small, mikro, or intermediate. The PLT1.M-M10 is a miniature tie with a one-piece construction design. It is made of nylon 6.6 and is suitable for indoor use.
As mentioned earlier, another common cable tie design consists of two pieces with a separate stainless steel barb that replaces the molded nylon barb in the one-piece design (Figur 2).

Figur 2: Single-piece fabrication with molded locking barbs (en) shown along with two-piece fabrication (b) using stainless steel barbs inserted after forming.
The aqua cable tie shown on the left in Figure 2 is one of the variants of Panduit’s PLT3S-C76 — PAN-TY@PLT series. It is made from ethylene tetrafluoroethylene (ETFE) and is suitable for applications requiring chemical resistance, flame retardancy and radiation resistance. The cable tie on the right in Figure 2 is Panduit’s BT4S-M0, a member of the DOME-TOP BARB-TY BT series, manufactured with individual barbs. I tillegg, this series of ties features rounded heads and rounded edges to minimize wear on the wire insulation. The black color is achieved by adding carbon black to the nylon, which improves resistance to UV rays, making this color more commonly used in outdoor applications.
Cable ties are manufactured from a range of materials specific to the environment in which they are intended to be used. The basic lacing is molded from nylon 6.6. Nylon 6.6 offers high mechanical strength, stivhet, good heat resistance and reasonable chemical resistance. Variants include weather-resistant, heat-stable and flame-retardant nylon 6.6.
Various other materials are used to achieve specific tolerances. For eksempel, the DT8EH-Q0 is designed for high strength as well as resistance to impact, kjemikalier, UV rays and weather. It uses acetal (polyoxymethylene, or POM), a range of materials including Delrin. It is 2.25 føtter (ft.) long and has a tensile strength of 250 pounds. These cable ties are designed for harsh outdoor applications in the power and communications industries.

temperaturområde
The temperature range that a cable tie can withstand depends primarily on the materials used in its construction. Nylon 6.6 is rated for an operating temperature range of -76°F to +185°F. Heat-stable nylon 6.6 extends the upper end of the range to 212°F. PEEK has the highest temperature tolerance, with an upper temperature limit of 500°F.

special function
The Panduit CBR1M-M, part of the Contour-Ty Series, features a unique design that prevents damage to wire insulation or cable jacketing. It features a low-profile head design that uses parallel inlets to limit exposure of sharp edges and reduce snags, og har låsende fordypninger på utsiden av stroppen (Figur 3).

Figur 3: Contour-Ty-serien bruker en låsemekanisme som er satt i rett vinkel på stroppseksjonen for parallell innføring og låser hakk på utsiden for å forhindre skade på isolasjonen.
