Il-materjal tal-kejbil għandu wkoll rwol deċiżiv fil-kwalità tal-kejbil. Fil-passat, kejbils tal-plastik kienu użati aktar spiss, imma gradwalment Kejbils tal-gomma beda jissostitwixxi l-kejbils tal-plastik. Hekk huwa minħabba kejbil tal-gomma għandu jkun l-aħjar. Hawnhekk ħalli l-editur tal-kumpanija tal-kejbil ZMS jispjega d-differenza bejn il-gomma u l-plastik.

Causes of Cable Fires and How to Deal with Them
According to the railroad station in Nanjing, at 18:20 on August 8, the Nanjing Yangtze River Bridge highway bridge below the attached place cable burst into flames and smoke, the fire department and the railroad units concerned quickly disposed of, affecting some trains late. The cause of the incident is under investigation.
Kif jaħdem il-kejbil tal-fibra ottika?
Il-fibra ottika kienet waħda mill-pilastri ewlenin tal-komunikazzjonijiet moderni. Għandu kapaċità ta 'komunikazzjoni kbira u distanza ta' trasmissjoni twila. Għandu wkoll il-vantaġġ li jkun sensittiv ħafna u immuni għall-interferenza elettromanjetika. Allura, kif eżattament il-fibra ottika tittrasmetti sinjali ottiċi?
What Is The Specific Classification Standard Of Cable Flame Retardant Grade?
Fil-preżent, the cable industry is accustomed to flame retardant (FireRetardant), LowSmokeHalogenFree (LSOH) or low halogen low smoke (LSF), fire-resistant (FireResistant), eċċ., with certain fire performance of the cable, are collectively referred to as fire-resistant cable.
What is FTTH Fiber Optic Cable? What Kind of Structural Features Does it Have?
I. Introduction Of FTTH Networks
With the development of optical communication networks and the deepening of fiber optic access, FTTH network construction is growing exponentially.
Fil-preżent, both China Telecom and China Netcom have indicated that they will invest huge amounts of money in the large-scale commercialization of FTTH.
Why Can’t High-Voltage Cables Be Buried Underground?
What Is A High-Voltage Cable?
Ultra-high voltage transmission refers to the use of 500 kV-1000 kV voltage levels to transmit electricity.
If the 220 kV transmission index is 100%, the relative investment per kilometer of UHV transmission, the relative cost per kilowatt-hour electricity transmission a hundred kilometers and the consumption of metal materials, eċċ., have been significantly reduced, and the line corridor utilization rate has been significantly improved.
In our daily lives, we can often see the overhead ultra-high voltage transmission project, whether we have thought about the question: why can not be like the city underground cable, high-voltage power lines all buried underground?
Importanti! Dak li għandek bżonn tkun taf dwar ir-rwol tal-ilqugħ fil-kejbils tal-kontroll
A kejbil tal-kontroll protett ġeneralment jintuża bħala l-linja ta 'konnessjoni ta' strumenti elettriċi.
Huwa adattat għal-linja ta 'konnessjoni ta' strumenti elettriċi b'vultaġġ AC-rated ta '450/750V u taħt u l-linja ta' trasmissjoni tas-sistema ta 'kontroll awtomatiku.
Għandu proprjetajiet eċċellenti bħar-reżistenza taż-żejt, reżistenza għall-ilma, reżistenza għall-ilbies, reżistenza għall-aċidu u l-alkali, reżistenza għal diversi gassijiet korrużivi, reżistenza għat-tixjiħ, u non-kombustibbiltà.
What Is The Source Of Electricity?
For contemporary people in most parts of the world, electricity is a necessity. It is an essential commodity that contributes to our comfort. Our jobs, gadgets, and most daily activities are directly dependent on our ability to access electricity.
Applications and Prospects of High Voltage DC Transmission Cable
From a worldwide perspective, high-voltage DC transmission cable is applied to the following areas such as long-distance high-capacity overhead transmission, power grid interconnection, and long-distance submarine cable transmission with obvious advantages.
6 Characteristics of Braided Cable
Braided cables are required for stability.
Crossed threads allow the braid to flex and stretch without bending, folding or kinking.
There are excellent electrical conductors braided cables and an electrostatic shield to ensure signal integrity.
Copper, tinned copper, and aluminum are examples of these conductors.
