Draad en kabel word gebruik om elektrisiteit oor te dra (magnetiese) energie. Inligting en die verwesenliking van elektromagnetiese energie-omsetting van draadprodukte. In die breë gesproke, draad en kabel word ook na verwys as kabel, en eng gesproke, kabel verwys na geïsoleerde kabel. Dit kan gedefinieer word as 'n versameling van die volgende dele: een of meer geïsoleerde draadkerne, en hulle mag hul bekleding hê, totale beskermende laag, en buitenste skede, die kabel kan ook addisionele geleiers sonder isolasie hê.

White Ceramics On Power Poles—Electrical Insulators
The main role of 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. Byvoorbeeld, two wires sometimes need to be connected and sometimes need to be disconnected. Op hierdie tydstip, they can be connected with terminals and disconnected at any time, It is convenient and fast without welding or winding them together.
Faktore wat die isolasieweerstand van draad- en kabelprodukte beïnvloed
Die isolasie weerstand van draad- en kabelprodukte meet hoofsaaklik die volumeweerstand van die kabelisolasielaag, die oppervlakweerstand kan nie gemeet word nie, en meer faktore beïnvloed die waarde van kabelisolasieweerstand. In praktiese toepassing, daar is vier hooffaktore op die isolasieweerstandskoëffisiënt.
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. Nietemin, 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. Daarom, 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, ens. 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. Nietemin, 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 cable laying into the pipeline.
