The material of the cable also plays a decisive role in the quality of the cable. In the past, 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.

Hogyan működik az optikai kábel?
A száloptika a modern kommunikáció egyik fő pillére. Nagy kommunikációs kapacitással és nagy átviteli távolsággal rendelkezik. Az is előnye, hogy nagyon érzékeny és immunis az elektromágneses interferenciára. Így, hogy a száloptika pontosan hogyan továbbítja az optikai jeleket?
What Is The Specific Classification Standard Of Cable Flame Retardant Grade?
Jelenleg, a cable industry is accustomed to flame retardant (FireRetardant), LowSmokeHalogenFree (LSOH) or low halogen low smoke (LSF), fire-resistant (FireResistant), stb., 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?
én. Introduction Of FTTH Networks
With the development of optical communication networks and the deepening of fiber optic access, FTTH network construction is growing exponentially.
Jelenleg, both China Telecom and China Netcom have indicated that they will invest huge amounts of money in the large-scale commercialization of FTTH.
Miért nem lehet a nagyfeszültségű kábeleket a föld alá temetni??
Mi az a nagyfeszültségű kábel?
Az ultranagy feszültségű átvitel használatára utal 500 kV-1000 kV feszültségszintek villamos energia továbbítására.
Ha a 220 kV átviteli index az 100%, az UHV átvitel kilométerenkénti relatív beruházása, az egy kilowattóra villamosenergia-átvitel relatív költsége száz kilométeren és a fémanyagok felhasználása, stb., jelentősen csökkentek, és jelentősen javult a vonalfolyosó kihasználtsága.
A mindennapi életünkben, gyakran láthatjuk a felső feletti ultranagyfeszültségű átviteli projektet, vajon átgondoltuk-e a kérdést: miért nem lehet olyan, mint a városi földkábel, magasfeszültségű vezetékek mind a föld alá temetve?
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, wear resistance, acid and alkali resistance, resistance to various corrosive gases, aging resistance, 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 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.
Réz, tinned copper, and aluminum are examples of these conductors.
