Sârmă și cablu sunt folosite pentru a transmite electricitate (magnetic) energie. Informarea și realizarea conversiei de energie electromagnetică a produselor din sârmă. În linii mari, firul și cablul sunt denumite și cablu, și în mod restrâns vorbind, cablu se referă la cablu izolat. Poate fi definit ca o colecție a următoarelor părți: unul sau mai multe miezuri de sârmă izolate, și pot avea placarea lor, strat protector total, și teaca exterioară, cablul poate avea si conductori suplimentari fara izolatie.

White Ceramics On Power Poles—Electrical Insulators
Rolul principal al electrical insulators is to provide mechanical fixation and electrical insulation for electrical equipment and conductors in power transmission and supply lines. Insulators are currently available in three main materials, namely ceramic, tempered glass, and organic composite materials. Insulators have played an important role in the development of the electric power industry.
How to Use The Terminal Block
The wiring terminal is used to facilitate the connection of wires. It is a metal sheet sealed in insulating plastic. There are holes at both ends to insert wires, and screws are used for fastening or loosening. De exemplu, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and disconnected at any time, It is convenient and fast without welding or winding them together.
Factori care afectează rezistența de izolație a produselor din sârmă și cablu
Rezistenta de izolare a produse de sârmă și cablu măsoară în principal rezistența de volum a stratului de izolație al cablului, rezistența suprafeței nu poate fi măsurată, și mai mulți factori afectează valoarea rezistenței de izolație a cablului. În aplicare practică, există patru factori principali asupra coeficientului de rezistență de izolație.
Tips for improving the overall performance of aluminum stranded wire with aluminum alloy core
The rated breaking force of the conductor is calculated based on the strength of all the aluminum single wires and reinforcements. Cu toate acestea, the actual braking force deviates from the true calculated value. The main reason for this is that the strength of every single wire is not fully utilized. Prin urmare, when designing the product not only to meet its minimum strength requirements but also to consider how the strength of every single wire is tapped out. Not only is it a full use of the material, but the overall performance of the wire will also be greatly improved.
What are the Functions and Uses of Fire-resistant Cables?
What is the definition of fire-resistant cable?
Fireproof cable is not a single cable, it is a general term for a class of cables. These cables include fire-resistant cables, flame-retardant cables, mineral-insulated non-combustible cables, etc. As long as the cables have fire resistance, they can be called fire-resistant cables.
Mechanical and Physical Properties of Conductor
Conductor Performance
Although high conductivity is an important indicator of a good or bad conductor, other factors must also be considered. Silver seems to be a good conductor. Cu toate acestea, its high cost makes users have to turn to other alternatives. Silver also has other disadvantages, such as lack of physical strength, which is necessary for the process of pozarea cablurilor into the pipeline.
