Armor cable: It is installed by different material conductors in a metal sleeve with insulating materials, and is processed into a bending solid combination.
Non-armor cable: cables without armor protective layers, from several or several sets of wires in each group of at least two twisted cables, each set of wires insulated, often surrounds a center Twisted. The entire outer bread has a highly insulated coverage layer.
Abstract: Qhia cov ntaub ntawv thiab cov qauv ntawm ib puag ncig tus phooj ywg mineral rwb thaiv tsev hluav taws cables, los ntawm kev tsim cov ntxhia hluav taws kub tiv thaiv insulating txheej, thermosetting polymer tiv thaiv txheej, inorganic fiber ntau, Tsis tshua muaj pa halogen-dawb silicon porcelain rwb thaiv tsev txheej, hlau armor fireproof txheej, txheej tiv thaiv hluav taws, thiab hlau armor fireproof txheej. Cov qauv sib xyaw refractory yog tsim los ntawm cov pa tsis muaj pa halogen-dawb ib puag ncig tiv thaiv sab nraud txheej txheej, paub txog kev tiv thaiv ib puag ncig ntawm cable hluav taws kub thiab tsis muaj tshuaj lom ib puag ncig tiv thaiv kev ua haujlwm, tsawg toxicity, thiab hluav taws-resistant cable.
Tus kis kab mob kev sib txuas taw tes yog qhov tseem ceeb tsis muaj zog ntawm kev ua haujlwm inline. Nyob rau hauv lub lag luam ntawm feem ntau tshav kub kub, yog li ua rau muaj hluav taws xob. Kev tsom xam ntawm cov xaim kev sib txuas taw tes cua sov teeb meem, thiab raws sij hawm siv cov kev tiv thaiv tsim nyog, yuav ua tau zoo kom tsis txhob muaj kev sib txuas ntawm cov xaim hluav taws xob overheating. Qhov no ua rau cov hlau txuas taw tes kom hlawv tawm qhov kev huam yuaj. Tshawb xyuas qhov ua rau ntawm cov xaim txuas ntawm qhov cua sov, thiab nkag siab txog lub hauv paus theoretical rau qhov kub thiab txias ntawm high-voltage kab. Nyob rau tib lub sijhawm, mastering kev tiv thaiv thiab kev daws teeb meem los daws qhov teeb meem kev sib txuas ntawm qhov cua sov, txhawm rau xyuas kom muaj kev nyab xeeb thiab txhim khu kev lag luam ntawm txoj kab muaj qhov ua tau zoo.
Fiber optic cable construction is roughly divided into the following steps: preparation → routing project → fiber optic cable laying → fiber optic cable splicing → project acceptance.
Tus zinc oxide ntes siv zinc oxide kuj yog lub ntsiab tivthaiv, uas zoo heev txhim kho cov yam ntxwv voltammetric ntawm tus ntes thiab ua kom muaj peev xwm dhau los ntawm tam sim no. Thaum tus neeg ntes tau ua haujlwm li qub, Qhov voltage ntws los ntawm tus ntes tam sim no tsuas yog microampere. Thaum lub overvoltage tau txais, cov yam ntxwv zoo uas tsis yog-linear ntawm tus ntes ua lub luag haujlwm zoo.
Lub teeb ntes hluav taws xob feem ntau yog siv los tiv thaiv cov khoom siv hluav taws xob los ntawm kev cuam tshuam ntawm xob laim overvoltage thiab kev khiav hauj lwm overvoltage ntawm nws cov khoom siv hluav taws xob rwb thaiv tsev..
Cov khoom siv rwb thaiv tsev ntawm cov hlau thiab cable yog cov qauv tseem ceeb los xyuas kom meej qhov kev ua haujlwm zoo ntawm tus neeg xyuas pib. Kev ua haujlwm lub neej ntawm cov khoom siv rwb thaiv tsev yog ib qho tseem ceeb qhia txog lub neej ntawm lub cable. Feem ntau, yog dab tsi rwb thaiv tsev cov ntaub ntawv peb siv rau hlau thiab cable?
High-voltage kab ntes rau 6 ~ 220kV AC kis tau tus mob kab, yog ib hom tshiab ntawm xob laim ntes tau raug tshem tawm thiab ntsia rau ntawm lub tshuab xa hluav taws xob.
In the case of high-voltage transmission line construction, many people working on projects often come across high-voltage power cable joints. Niaj hnub no, I would like to discuss the types of high voltage power cable joints and their applications with you. Thawj, let’s talk about what high voltage power cable joints are.
Lub luag haujlwm tseem ceeb ntawm heat shrink tubing in a circuit is to protect important devices and circuits from damage and impact. Although it does not have any particular impact on the operation of the circuit, it is often the key point that determines the success or failure of the entire design. With the rapid development of the electronics industry, flame-retardant heat shrink tubing is also inseparable from the electronics industry, more and more electronic products need to use flame retardant heat shrink tubing for protection. The flame retardant processing of the heat shrink tube, when attacked by external fire sources, can effectively block, delay or stop the transmission of flame, to achieve the effect of flame retardant.
Nyob rau tam sim no, cov kab hluav taws xob overhead yog siv los thauj hluav taws xob mus ntev. Pa cables feem ntau yog aluminium conductor steel reinforced (ACSR). Txij xyoo 1990s, carbon fiber composite cores (aluminium conductor composite core) tau siv los ua cov core bar ntawm cables. ACCC muaj qhov zoo hauv qab no tshaj li cov neeg coj ua ib txwm muaj.
