Sreang agus cábla úsáidtear iad chun leictreachas a tharchur (maighnéadach) fuinneamh. Faisnéis agus réadú chomhshó fuinnimh leictreamaighnéadach ar tháirgí sreinge. Go ginearálta, tugtar cábla ar shreang agus ar chábla freisin, agus caol ag labhairt, Tagraíonn cábla do chábla inslithe. Is féidir é a shainiú mar bhailiúchán de na codanna seo a leanas: croíthe sreang inslithe amháin nó níos mó, agus b’fhéidir go mbeadh an cumhdach acu, ciseal cosanta iomlán, agus sheath seachtrach, is féidir seoltóirí breise a bheith ag an gcábla gan insliú freisin.

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. Mar shampla, 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.
Factors Affecting the Insulation Resistance of Wire and Cable Products
The insulation resistance of wire and cable products mainly measures the volume resistance of the cable insulation layer, the surface resistance cannot be measured, and more factors affect the value of cable insulation resistance. In practical application, there are four main factors on the insulation resistance coefficient.
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. Cén dóigh faoin spéir a ...?, 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. Dá bhrí sin, 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 cábla, it is a general term for a class of cables. These cables include fire-resistant cables, flame-retardant cables, mineral-insulated non-combustible cables, sreoir. As long as the cables have fire resistance, they can be called fire-resistant cables.
Airíonna Meicniúla agus Fisiceacha an Seoltóra
Feidhmíocht Seoltóra
Cé go bhfuil seoltacht ard ina tháscaire tábhachtach ar sheoltóir maith nó olc, ní mór fachtóirí eile a chur san áireamh freisin. Is cosúil gur seoltóir maith é Silver. Cén dóigh faoin spéir a ...?, Fágann a chostas ard go mbíonn ar úsáideoirí dul chuig roghanna eile. Tá míbhuntáistí eile ag Silver freisin, mar shampla easpa neart coirp, atá riachtanach don phróiseas de leagan cábla isteach sa phíblíne.
