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.
Astratt: Introduċi l-materjali u l-istrutturi ta ' favur l-ambjent Kejbils tan-nar ta' insulazzjoni minerali, permezz tad-disinn ta ' saffi minerali iżolanti prevenzjoni tan-nirien, saffi protettivi ta' polimeru termosetting, mili tal-fibra inorganika, saff ta 'insulazzjoni tal-porċellana tas-silikon mingħajr duħħan baxx ta' aloġenu, armatura tal-metall saff nar, saff ta' prevenzjoni tan-nirien, u armatura tal-metall saff nar. L-istruttura refrattarja komposta hija magħmula minn saff ta 'kura esterna ta' protezzjoni ambjentali mingħajr duħħan baxx ta 'aloġenu, tirrealizza l-protezzjoni ambjentali tar-reżistenza għan-nar tal-kejbil u l-prestazzjoni ta 'protezzjoni ambjentali tossika baxxa, tossiċità baxxa, u kejbil reżistenti għan-nar.
Il linja ta 'trasmissjoni punt ta 'konnessjoni huwa punt dgħajjef ewlieni ta' operazzjoni inline. Fl-operazzjoni ta 'spiss sħana maħruqa, b'hekk jikkawża qtugħ tad-dawl. L-analiżi tal-problema tat-tisħin tal-punt tal-konnessjoni tal-wajer, u l-adozzjoni f'waqtha ta' miżuri preventivi xierqa, se jevita b'mod effettiv il-punt tal-konnessjoni tal-wajer sħana żejda. Dan jikkawża li l-punt tal-konnessjoni tal-wajer jinħaraq l-inċident. Analizza l-kawżi tat-tisħin tal-punt tal-konnessjoni tal-wajer, u tifhem il-bażi teoretika għaż-żieda fit-temperatura tal-linji ta 'vultaġġ għoli. Fl-istess ħin, nikkontrollaw il-miżuri ta 'prevenzjoni u soluzzjoni biex tittratta l-problema tat-tisħin tal-punt ta' konnessjoni, biex jiġi żgurat li l-operat sikur u affidabbli tal-linja għandu sinifikat prattiku.
Fiber optic cable construction is roughly divided into the following steps: preparation → routing project → fiber optic cable laying → fiber optic cable splicing → project acceptance.
Il zinc oxide arrester uses zinc oxide resistance as the main component, which greatly improves the voltammetric characteristics of the arrester and increases the through-current capability. When the arrester is in normal operation, the voltage flow through the arrester current is only microampere. When the overvoltage is received, the excellent non-linear characteristics of the arrester play a good role.
A lightning arrester is mainly used to protect electrical equipment from lightning intrusion overvoltage and operating overvoltage on its power equipment insulation damage.
The insulation material of wire and cable is an important structure to ensure the proper operation of the conductor. The operating life of the insulation material is an important indicator of the life of the cable. Normalment, what are the insulation materials we use for wire and cable?
High-voltage line arrester for 6 ~ 220kV AC transmission lines, is a new type of lightning arrester suspended and installed on the transmission tower.
In the case of high-voltage transmission line construction, many people working on projects often come across high-voltage power cable joints. Illum, I would like to discuss the types of high voltage power cable joints and their applications with you. L-ewwel, let’s talk about what high voltage power cable joints are.
The main role of 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.
Fil-preżent, overhead cables are used to transport electricity over long distances. Conventional cables are mostly aluminum conductor steel reinforced (ACSR). Since the 1990s, carbon fiber composite cores (aluminum conductor composite core) have been used as the core bar of cables. ACCC has the following advantages over traditional conductors.
