Wire and cable are used to transmit electrical (magnetic) energy. Information and the realization of electromagnetic energy conversion of wire products. Uopšteno govoreći, wire and cable are also referred to as cable, and narrowly speaking, cable refers to insulated cable. It can be defined as a collection of the following parts: one or more insulated wire cores, and they may have their cladding, total protective layer, and outer sheath, the cable can also have additional conductors without insulation.

Bijela keramika na električnim stupovima—električni izolatori
Glavna uloga električni izolatori je obezbjeđivanje mehaničke fiksacije i električne izolacije za električnu opremu i provodnike u vodovima za prijenos i napajanje. Izolatori su trenutno dostupni u tri glavna materijala, naime keramika, kaljeno staklo, i organskih kompozitnih materijala. Izolatori su odigrali važnu ulogu u razvoju elektroprivrede.
Kako koristiti terminalski blok
Terminal za ožičenje se koristi za olakšavanje spajanja žica. To je metalni lim zapečaćen izolacionom plastikom. Na oba kraja postoje rupe za umetanje žica, a vijci se koriste za pričvršćivanje ili otpuštanje. Na primjer, dvije žice ponekad moraju biti spojene, a ponekad ih je potrebno odvojiti. U ovo vrijeme, mogu se spojiti na terminale i isključiti u bilo koje vrijeme, Zgodno je i brzo bez zavarivanja ili namotavanja.
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. Međutim, 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. Stoga, 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 kabl, it is a general term for a class of cables. These cables include fire-resistant cables, flame-retardant cables, mineral-insulated non-combustible cables, itd. 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. Međutim, 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.
