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.
Sažetak: Uvesti materijale i strukture koje su ekološki prihvatljive protupožarni kabeli s mineralnom izolacijom, kroz projektiranje mineralnih protupožarnih izolacijskih slojeva, termoreaktivni polimerni zaštitni slojevi, punilo od anorganskih vlakana, Silikonski porculanski izolacijski sloj bez dima bez halogena, metalni oklop vatrootporni sloj, protupožarni sloj, i metalni oklop vatrootporni sloj. Kompozitna vatrostalna struktura sastoji se od vanjskog sloja za njegu okoliša bez halogena i niske razine dima, ostvarivanje zaštite okoliša otpornosti kabela na vatru i zaštite okoliša niske toksičnosti, niska toksičnost, i vatrootporni kabel.
The dalekovod točka povezivanja glavna je slaba točka inline rada. Tijekom rada često dolazi do izgaranja topline, uzrokujući tako nestanak struje. Analiza problema zagrijavanja mjesta spajanja žice, te pravovremeno poduzimanje odgovarajućih preventivnih mjera, učinkovito će izbjeći pregrijavanje točke spajanja žice. To uzrokuje nesreću na mjestu spajanja žice. Analizirajte uzroke zagrijavanja mjesta spajanja žice, te razumjeti teorijsku osnovu porasta temperature visokonaponskih vodova. Istovremeno, ovladavanje mjerama prevencije i rješavanja problema grijanja priključne točke, kako bi se osigurao siguran i pouzdan rad linije ima praktično značenje.
Konstrukcija optičkog kabela ugrubo je podijeljena u sljedeće korake: priprema → projekt trasiranja → polaganje optičkog kabela → spajanje optičkog kabela → prihvaćanje projekta.
The odvodnik cinkovog oksida koristi otpornost na cinkov oksid kao glavnu komponentu, što znatno poboljšava voltametrijske karakteristike odvodnika i povećava sposobnost prolazne struje. Kada je odvodnik u normalnom pogonu, protok napona kroz struju odvodnika je samo mikroamper. Kada se primi prenapon, izvrsne nelinearne karakteristike odvodnika igraju dobru ulogu.
Odvodnik groma uglavnom se koristi za zaštitu električne opreme od prenapona upada groma i radnog prenapona na oštećenju izolacije energetske opreme.
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. Usually, 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. Danas, I would like to discuss the types of high voltage power cable joints and their applications with you. Prvi, 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.
Trenutno, 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.
