Oklopni kabl: Ugrađuje se pomoću provodnika od različitih materijala u metalnu navlaku sa izolacionim materijalima, i obrađuje se u čvrstu kombinaciju savijanja.
Neoklopni kabl: kablovi bez oklopnih zaštitnih slojeva, od nekoliko ili više setova žica u svakoj grupi od najmanje dva upletena kabla, svaki set žica izolovan, često okružuje centar Twisted. Cijeli vanjski kruh ima visokoizolirani pokrivni sloj.
Sažetak: Uvesti materijale i strukture ekološki prihvatljivih Vatreni kablovi mineralnih izolacije, Kroz dizajniranje mineralnih izolacijskih slojeva sprečavanja vatre, Termosetting polimerni zaštitni slojevi, punilo neorganskih vlakana, Niski dimni silikonski izolacijski sloj od halogena, metalni oklop vatrootporni sloj, Sloj za prevenciju vatre, i metalni oklop vatrootporni sloj. Kompozitna vatrostalna struktura sastoji se od niskog sloja za zaštitu okoliša bez halogena, Realizacija zaštite okoliša za otpornost na kablovsku požar i performanse niskog otrovnog zaštite okoliša, niska toksičnost, i kabl otporan na vatru.
The dalekovod tačka povezivanja je glavna slaba tačka inline operacije. U radu često gori, što dovodi do nestanka struje. Analiza problema grijanja mjesta spajanja žice, i blagovremeno donošenje odgovarajućih preventivnih mjera, efektivno će izbjeći pregrijavanje priključka žice. To uzrokuje da mjesto spajanja žice izgori u nesreći. Analizirajte uzroke zagrijavanja priključne točke žice, i razumjeti teorijsku osnovu za porast temperature visokonaponskih vodova. U isto vreme, savladavanje mjera prevencije i rješavanja problema grijanja priključnih mjesta, osiguravanje sigurnog i pouzdanog rada linije ima praktičan značaj.
Fiber optic cable construction is roughly divided into the following steps: preparation → routing project → fiber optic cable laying → fiber optic cable splicing → project acceptance.
The 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. 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. Prvo, 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.
