Sab nraum zoov vs. Sab hauv Fiber Patch Cords: Vim li cas qhov txawv qhov teeb meem

Cov khoom sib txawv: PU vs PVC

Feem ntau cov qauv sab hauv tsev patch cords siv PVC (polyvinyl chloride) tsho. Nws yog pheej yig, hloov tau, thiab tsim nyog rau kev tswj hwm hauv tsev ib puag ncig zoo li cov chaw zov me nyuam, cov khoom siv chav, thiab chaw ua haujlwm cabling.

Sab nraum zoov thaj cords siv lwm yam nkaus. Lub OM3 sab nraum zoov qaum nta cov nplaim hluav taws-retardant, siab-toughness polyurethane (PU) elastomer sheath. Qhov no tsis yog qhov txawv ntawm kev lag luam - nws yog ib qho tseem ceeb ntawm cov khoom sib txawv nrog rau qhov tiag - ntiaj teb cuam tshuam.

PU Jacket muaj:

• Cov pa oxygen siab siab thiab cov nplaim hluav taws zoo heev - nws tiv thaiv hluav taws thiab tsis tuaj yeem tawm nplaim taws

• Roj thiab tshuaj tiv thaiv - qhov tseem ceeb rau kev lag luam ib puag ncig uas cov cables yuav raug rau cov kua dej hydraulic, cov kuab tshuaj, los yog lwm yam khoom corrosive

• Tear resistance - nws tiv taus lub cev puas thiab cov npoo ntse uas yuav ua rau PVC sai sai

• Tsawg-kub yooj yim - nws tseem pliable nyob rau hauv txias tej yam kev mob uas PVC ua nkig thiab tawg

• Kev ntxhov siab buffering thiab siab -resistant durability - nws absorbs txhua yam kev ntxhov siab uas yuav hloov mus rau cov fibers hauv qhov muag

Standard PVC tsis muaj cov khoom no. Nws yog qhov zoo rau kev tswj hwm ib puag ncig sab hauv tsev. Sab nraum zoov, nws yog lub luag haujlwm. Sab hauv PVC thaj cords tej zaum yuav muaj hnub nyoog, tawg, los yog tawv nyob rau hauv lub sij hawm ntev - raug tshav ntuj, ua rau lawv tsis haum rau kev siv sab nraum zoov tas li.

Qhov Sib txawv ntawm Cov Qauv: Ua kom Tau Txais Kev Sib Tw

Tus qauv sab hauv tsev patch cords muaj kev tsim kho yooj yim: fiber ntau, tsis muaj zog, cov tswv cuab lub zog (feem ntau aramid xov paj), thiab lub tsho. Lawv tau tsim los ua tib zoo saib xyuas hauv ib puag ncig tiv thaiv.

Sab nraum zoov thaj cords yog tsim txawv. OM3 sab nraum zoov qaum suav nrog ntau yam qauv uas ua rau nws muaj zog dua:

Aramid- txhawb nqa ib leeg-strand configurations muab lub cable nrog lub qhov rais dav tensile lim. Hauv lus Askiv dawb: koj tuaj yeem rub nws nyuaj dua yam tsis muaj kev puas tsuaj rau cov fibers hauv. Qhov no tseem ceeb thaum lub sij hawm installation los ntawm conduits, nyob ib ncig ntawm cov ces kaum, thiab hla cable tais - tag nrho cov kev khiav hauj lwm uas cuam tshuam cov cable rau mechanical stress.

Ib txheej txheej txheej tshwj xeeb thiab cov qauv sib xyaw thib ob nqus cov neeg kho tshuab thiab ib puag ncig kev ntxhov siab, txo qis ntxiv qhov muag cable poob.
