The material of the cable also plays a decisive role in the quality of the cable. In die verlede, plastic cables were used more often, but gradually rubber cables began to replace plastic cables. So is it because rubber cable must be the best. Here let ZMS cable company’s editor explain the difference between rubber and plastic.

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.
Hoe werk optiese veselkabel?
Veseloptika was een van die hoofpilare van moderne kommunikasie. Dit het 'n groot kommunikasiekapasiteit en lang transmissieafstand. Dit het ook die voordeel dat dit hoogs sensitief en immuun teen elektromagnetiese interferensie is. Dus, hoe presies stuur veseloptika optiese seine uit?
Wat is die spesifieke klassifikasiestandaard van kabelvlamvertragergraad?
Op die oomblik, die kabel industrie is gewoond aan vlamvertrager (Brandvertrager), LaagrookHalogenvry (LSOH) of lae halogeen lae rook (LSF), brandbestand (Vuurbestand), ens., met sekere brandprestasie van die kabel, word gesamentlik na verwys as brandbestande kabel.
What is FTTH Fiber Optic Cable? What Kind of Structural Features Does it Have?
ek. Introduction Of FTTH Networks
With the development of optical communication networks and the deepening of fiber optic access, FTTH network construction is growing exponentially.
Op die oomblik, both China Telecom and China Netcom have indicated that they will invest huge amounts of money in the large-scale commercialization of FTTH.
Waarom kan hoogspanningskabels nie ondergronds begrawe word nie?
Wat is 'n hoëspanningskabel?
Ultrahoë spanning transmissie verwys na die gebruik van 500 kV-1000 kV spanningsvlakke om elektrisiteit oor te dra.
As die 220 kV transmissie-indeks is 100%, die relatiewe belegging per kilometer van UHV-transmissie, die relatiewe koste per kilowatt-uur elektrisiteitsoordrag 'n honderd kilometer en die verbruik van metaalmateriaal, ens., aansienlik verminder is, en die gebruikskoers van die lynkorridor is aansienlik verbeter.
In ons daaglikse lewe, ons kan dikwels die oorhoofse ultrahoëspanning transmissieprojek sien, of ons oor die vraag gedink het: hoekom kan nie soos die stad ondergrondse kabel, hoogspanning kraglyne almal ondergronds begrawe?
Important! What You Need To Know About The Role Of Shielding In Control Cables
A shielded control cable is generally used as the connection line of electrical instruments.
It is suitable for the connection line of electrical instruments with an AC-rated voltage of 450/750V and below and the transmission line of the automatic control system.
It has excellent properties such as oil resistance, water resistance, slytasie weerstand, acid and alkali resistance, resistance to various corrosive gases, weerstand teen veroudering, and non-combustibility.
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 Eienskappe van gevlegte kabel
Gevlegte kabels word benodig vir stabiliteit.
Gekruiste drade laat die vlegsel buig en strek sonder om te buig, vou of knik.
Daar is uitstekende elektriese geleiers gevlegde kabels en 'n elektrostatiese skild om seinintegriteit te verseker.
Koper, geblikte koper, en aluminium is voorbeelde van hierdie geleiers.
