Kabel Armor: Iki dipasang dening konduktor materi sing beda-beda ing lengen logam kanthi bahan insulasi, lan diolah dadi kombinasi padat mlengkung.
Kabel non armor: kabel tanpa lapisan protèktif waja, saka sawetara utawa sawetara set kabel ing saben klompok paling ora rong kabel bengkong, saben set kabel terisolasi, asring ngubengi tengah Twisted. Roti njaba kabeh nduweni lapisan jangkoan sing terisolasi.
Abstract: Introduce the materials and structures of environmentally friendly mineral insulation fire cables, through designing mineral fire prevention insulating layers, thermosetting polymer protective layers, inorganic fiber filler, low smoke halogen-free silicon porcelain insulation layer, metal armor fireproof layer, fire prevention layer, and metal armor fireproof layer. The composite refractory structure is composed of low -smoke halogen-free environmental protection external care layer, realizing the environmental protection of cable fire resistance and low toxic environmental protection performance, low toxicity, and fire-resistant cable.
The saluran transmisi titik sambungan minangka titik lemah utama saka operasi inline. Ing operasi asring panas diobong, saengga nyebabake listrik mati. Analisis masalah pemanasan titik sambungan kabel, lan adopsi pas wektune langkah-langkah pencegahan sing cocog, èfèktif bakal supaya titik sambungan kabel overheating. Iki nyebabake titik sambungan kabel kanggo ngobong kacilakan. Analisa panyebab pemanasan titik sambungan kabel, lan ngerti basis teori kanggo munggah suhu saka garis voltase dhuwur. Ing wektu sing padha, nguwasani langkah-langkah pencegahan lan solusi kanggo ngatasi masalah pemanasan titik sambungan, kanggo mesthekake operasi aman lan dipercaya saka baris wis pinunjul praktis.
Konstruksi kabel serat optik kira-kira dipérang dadi langkah-langkah ing ngisor iki: persiapan → proyek routing → pemasangan kabel serat optik → penyambungan kabel serat optik → penerimaan proyek.
The penahan seng oksida nggunakake resistance seng oksida minangka komponen utama, kang nemen mbenakake karakteristik voltammetric arrester lan nambah kemampuan liwat-saiki. Nalika arrester ing operasi normal, the voltage flow through the arrester current is only microampere. Nalika overvoltage ditampa, ciri non-linear banget saka arrester muter peran apik.
Penangkap petir utamane digunakake kanggo nglindhungi peralatan listrik saka overvoltage intrusi kilat lan overvoltage operasi ing karusakan insulasi peralatan listrik..
Bahan insulasi kabel lan kabel minangka struktur penting kanggo njamin operasi konduktor sing tepat. Umur operasi bahan insulasi minangka indikator penting kanggo urip kabel. Biasane, apa sing bahan isolasi sing digunakake kanggo kabel lan kabel?
Arrester baris voltase dhuwur kanggo 6 ~ 220kV saluran transmisi AC, iku jinis anyar saka arrester kilat dilereni soko tugas lan diinstal ing menara transmisi.
Ing cilik saka construction line transmisi voltase dhuwur, akeh wong sing nggarap proyek asring nemoni sambungan kabel listrik voltase dhuwur. Dina iki, Aku seneng ngrembug jinis sambungan kabel daya voltase dhuwur lan aplikasi karo sampeyan. Pisanan, ayo ngomong apa sambungan kabel daya voltase dhuwur yaiku.
Peran utama saka 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.
Saiki, kabel nduwur sirah digunakake kanggo ngeterake listrik ing jarak adoh. Kabel konvensional biasane dikuatake baja konduktor aluminium (Acsr). Wiwit taun 1990-an, inti komposit serat karbon (inti komposit konduktor aluminium) wis digunakake minangka bar inti saka kabel. ACCC nduweni kaluwihan ing ngisor iki tinimbang konduktor tradisional.
