Bare wires and bare conductor products refer to conductive wires without insulation and sheath, mainly including bare single wire, bare stranded wire and profiled wire. Copper aluminum single wire: including soft copper single wire, hard copper single wire, soft aluminum single wire and hard...

The storage and transportation of wire and cable products are two important links, if the storage and transportation methods are inappropriate, it will cause damage to the quality of wire and cable products and affect the safety of use, and may even cause accidents. Therefore, the storage and...

The model composition and sequence of wires and cables are as follows [1: Category, Purpose] [2: Conductor] [3: Insulation] [4: Inner cladding] [5: Structural features] [6: Outer cladding or derivation] [7: [Making Manganese] Power cable armor and outer sheath digital Digitally mark armor...

Refers to Category 6 network cable (twisted pair) in TIA/EIA standard. The standard channel bandwidth is 250 MHz. It may also be a Category 6 standard, either shielded or unshielded. UTP（Unshielded Twisted Pair）6 Refers to unshielded Category 6 twisted pair, and UTP corresponds to FTP...

Electrolytic copper is melted while it is added. The molten copper water has no conditions for full reduction. The whole melting process and copper water production process cannot be isolated from oxygen, so the oxygen content is very high. The fuel for molten copper is generally gas, which will...

In winter, as the temperature plummets, it has brought some impact to the wire and cable industry, and the more obvious impact is that the difficulty of cable laying has increased. So in such a situation, how should we start when laying cables in winter, and how to make full preparations to...

China is at a stage of rapid development, and the rejuvenation of the Chinese nation is also an important task for the leaders of our country. Because neither daily life nor modern military power can be separated from power resources, so can not be separated from wires and cables. Wire and cable...

Wire circuits are hidden projects, even small hidden dangers may cause serious safety accidents, so we must make sufficient preparations before the line laying, for example, in the selection of wires and cables, it is necessary to determine the appropriate cable according to many considerations....

In fact, there is no strict boundary between "wire" and "cable". Generally, products with small number of cores, small diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables; Larger conductor cross-section (more than 6 mm2) is...

Bare wire and bare conductor products The main characteristics of this type of products are: pure conductor metal, no insulation and sheath layer. This kind of wire can be used as a conductive wire, can also be used as electrical appliances and other equipment components, etc., its conductivity,...

When the load current increases, the surface temperature of the cable will rise, and if it is not treated, the consequences are very serious. For example: PVC cable, the surface temperature is 70°C, and its surface temperature will be lower than 5-10°C. Therefore, below 60 °C, the surface...

About wires and cables Wires and cables are wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in the broad sense are also referred to as cables, and cables in the narrow sense are insulated cables, which can be...

Wire and cable: It is usually made of several wires or groups of wires [at least two in each group] twisted together, similar to rope. Each group of wires is insulated from each other, and is often twisted around a center, with a highly insulated covering layer on the whole. It is mainly used to...

Compared with the service life of non-standard wire and cable, there is no doubt that the service life of national standard cable is long. Next, we will briefly analyze what are the hidden dangers of non-standard cables: 1. The insulation layer of non-standard wire and cable mainly plays the...

Cross-linked insulation cores sometimes have raw rubber phenomenon in the production process, which also become insulation rigid blocks or hard blocks. The main reasons for this phenomenon are: (1) The temperature of the machine neck or head is not enough, resulting in local cold glue inside;...

List of cable specifications and models Hardware model: insulated conductor BV wire GB standard 10 square wire System version: Wire system Cable specifications are the meaning of the representation of the number of cores and cross-sectional dimensions of wires and cables. The wire and cable...

With the popularization of safety concepts, the quality and performance requirements of wire and cable in various fields are getting higher and higher. It is reported that in recent years, more than 60% of all kinds of electrical fires in China are caused by wires and cables. When ordinary...

1. The aggravation of industry integration and industrialization development tend to be significant, and the market concentration of the industry will be further improved Wire and cable manufacturing enterprises have significant scale effect utility. The more large-scale companies in the...

The reason for blackening of wires and cables is simply summarized as "water ingress, moisture ingress and air intrusion of wires and cables". During production, transportation, storage and laying, wires and cables are exposed to wet environment or rainwater invades the cable conductor, which...

(1) Power system: overhead bare wires, busbars (busbars), power cables (plastic cables, oil-paper cables (basically replaced by plastic power cables), rubber cables, overhead insulated cables), branch cables (replacing part of the busbars), electromagnetic wires and wire cables for electrical...
