Wire and cable are used to transmit electrical (magnetic) energy. Information and the realization of electromagnetic energy conversion of wire products. Broadly speaking, 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.

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. Барои намуна, 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. Бо вуьуди он, 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. Ҳамин тавр, 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 кабел, it is a general term for a class of cables. These cables include fire-resistant cables, flame-retardant cables, mineral-insulated non-combustible cables, ғайра. 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. Бо вуьуди он, 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.
