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.

Kauri nyeupe kwenye miti ya nguvu -insulators za umeme
Jukumu kuu la insulators za umeme ni kutoa urekebishaji wa mitambo na insulation ya umeme kwa vifaa vya umeme na conductors katika maambukizi ya nguvu na mistari ya usambazaji. Insulators zinapatikana kwa sasa katika vifaa vitatu kuu, ambayo ni kauri, glasi iliyokasirika, na vifaa vya kikaboni. Wahamasishaji wamecheza jukumu muhimu katika maendeleo ya tasnia ya umeme.
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. Kwa mfano, 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. Walakini, 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. Kwa hivyo, 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.
Je! Ni kazi gani na matumizi ya nyaya sugu za moto?
Je! Ni ufafanuzi gani wa cable sugu ya moto?
Cable ya kuzuia moto sio moja cable, ni neno la jumla kwa darasa la nyaya. Nyaya hizi ni pamoja na nyaya sugu za moto, nyaya za moto-retardant, Kamba za madini-zisizo na bima, nk. Kwa muda mrefu kama nyaya zina upinzani wa moto, Wanaweza kuitwa nyaya sugu za moto.
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. Walakini, 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.
