Pantserkabel: Dit word deur verskillende materiaalgeleiers in 'n metaalhuls met isolerende materiale geïnstalleer, en word verwerk tot 'n buigende soliede kombinasie.
Nie-pantserkabel: kabels sonder pantserbeskermende lae, van verskeie of verskeie stelle drade in elke groep van ten minste twee gedraaide kabels, elke stel drade geïsoleer, dikwels omring 'n sentrum Twisted. Die hele buitebrood het 'n hoogs geïsoleerde deklaag.
Abstrak: Stel die materiale en strukture van omgewingsvriendelike bekend minerale isolasie brandkabels, deur die ontwerp van isolerende lae vir mineraalbrandvoorkoming, termohardende polimeer beskermende lae, anorganiese vesel vuller, lae rook halogeenvrye silikon porselein isolasie laag, metaal pantser vuurvaste laag, brandvoorkomingslaag, en metaal pantser vuurvaste laag. Die saamgestelde vuurvaste struktuur is saamgestel uit lae-rook halogeen-vrye omgewingsbeskerming eksterne sorg laag, die realisering van die omgewingsbeskerming van kabelbrandweerstand en lae giftige omgewingsbeskermingsprestasie, lae toksisiteit, en brandbestande kabel.
Die transmission line connection point is a major weak point of inline operation. In the operation of often heat burned, thus causing power outages. The analysis of the wire connection point heating problem, and timely adoption of appropriate preventive measures, will effectively avoid the wire connection point overheating. This causes the wire connection point to burn off the accident. Analyze the causes of wire connection point heating, and understand the theoretical basis for the temperature rise of high-voltage lines. Terselfdertyd, mastering the prevention and solution measures to deal with the connection point heating problem, to ensure the safe and reliable operation of the line has practical significance.
Fiber optic cable construction is roughly divided into the following steps: preparation → routing project → fiber optic cable laying → fiber optic cable splicing → project acceptance.
Die sinkoksied 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.
Die isolasiemateriaal van draad en kabel is 'n belangrike struktuur om die behoorlike werking van die geleier te verseker. Die lewensduur van die isolasiemateriaal is 'n belangrike aanduiding van die lewensduur van die kabel. Gewoonlik, wat is die isolasiemateriaal wat ons vir draad en kabel gebruik?
Hoë-spanning lyn arrester vir 6 ~ 220kV AC transmissielyne, is 'n nuwe soort weerligafleier wat op die transmissietoring opgehang en geïnstalleer is.
In the case of high-voltage transmission line construction, many people working on projects often come across high-voltage power cable joints. Vandag, I would like to discuss the types of high voltage power cable joints and their applications with you. Eerste, let’s talk about what high voltage power cable joints are.
Die hoofrol van 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.
Op die oomblik, oorhoofse kabels word gebruik om elektrisiteit oor lang afstande te vervoer. Konvensionele kabels is meestal aluminium geleierstaal versterk (ACSR). Sedert die 1990's, koolstofvesel saamgestelde kerns (aluminium geleier saamgestelde kern) is gebruik as die kernstaaf van kabels. ACCC het die volgende voordele bo tradisionele geleiers.
