Why Choose Multi-Core Power Cables?

Power cables are an essential bridge for transmitting electricity and play an indispensable role in production life.

The emergence of power cables. They have greatly improved the safety of power generation, transmission, transformation, power supply, distribution, and use.   Electric power cables find application in different environments such as industrial production, power transmission, aerospace, and naval warships. So how to make cable stability should be the first consideration in the production and welding of power cables.



The Birth of Multi-Core Power Cables

The first to emerge was the single-core power cable. But single-core power cables could not meet the needs of using a three-phase four-wire or multi-loop power supply. 

In addition, the high laying requirements of single-core power cables and the shortcomings of taking up a lot of space limited the development of industrial production. Especially when the electric lines need multiple, multi-layer placement, and the space for installation and installation conditions are limited. The single-core power cable is not very convenient to use. Therefore, a multi-core power cable was developed and quickly entered the field of power applications, accepted and used by many users.

Therefore, multi-core power cables have emerged. The core refers to the insulated line core, and a multi-core cable is a cable with more than one insulated core.

Common Multi-Core Power Cables



Multi-core power cables have a variety of structures depending on the number of cores. We commonly have two-core, three-core, four-core, five-core, 3+1-core, 3+2-core, 4+1-core, etc. The number of cores of control power cables can even reach 61 cores.

A two-core cable can control an appliance. It has two cores, the firewire,  and the zero wire.

Three-core, generally 380V power line, there are three cores, one is zero, the remaining two are fire, three gate switch or magnetic starter control appliances and power. It can use for the three-phase motor or welding machine;

Four-core, often can be used in the incoming power line, there are four cores, one connected to the zero wire, the other three can connect with the transformer A, B, C fire line, A, B, C fire line, the end of all the power consumption is roughly equal, so that the transformer output power smooth;

Five-core, generally used in small spaces where there are many appliances. The four-core power cord can control five electrical devices. Five electrical appliances share a zero wire.

The Benefits of Using a Multi-Core Power Cable

1. Multi-core can evenly distribute the current, reducing the skin effect of the cable, reducing circuit losses, and extending the service life of the power cable.

2. Multi-core cable is more flexible than single-core cable, will not easily break, easy to operate.

3. Not limited by time and space, easy to use.

4. Low laying requirements, easy to lay.

Cable Popular Science Series--What's the different between XLPE cable and PVC cable?

图片
XLPE is a new insulation material. He had PE got by crosslinking.  So theoretically, his performance is better than the PE.  XLPE has been used in the cable industry since it was invented in the 1960 s and 1970 s.  Until now, XLPE has become head insulation in the cable industry. Here about the advantages and uses of XLPE  Advantages of XLPE cable XLPE   The advantages are as follows:   😊 I t can work at 90℃ high temperature for a long time . A nd  it  has excellent heat resistance . It also means it can withstand higher current ratings . 😊 I nsulation enhancement  and t he effect of temperature on the material is reduced . 😊  A ll-round improvement of mechanical characteristics,   no longer easy to crack due to environmental factors .  I mprove heat aging performance.  😊 R educe the harm to the environment,   in line with modern environmental protection requirements .  Easy operation and maintenance 😊 L ow ...

¿Cuál es la diferencia entre cable resistente al fuego y cable retardante de llama?

图片
En primer lugar, debemos saber que los Cable resistente al fuego y los cables ignífugos , que tienen cierto comportamiento frente al fuego, pertenecen al mismo Cable fire resistente. Definición de cable ignífugo y Cable resistente al fuego Los cables resistentes al fuego tienen la capacidad de funcionar en caso de incendio, pero no pueden evitar que el fuego se propague. Los cables ignífugos pueden prevenir la propagación del fuego, pero cuando ocurre un incendio, el aumento de la temperatura exterior evitará que continúe funcionando. La temperatura tolerable de los cables resistentes al fuego en general es generalmente inferior a 750 °, y el tiempo de funcionamiento a alta temperatura no supera los 90 minutos. Pero también hay un cable resistente al fuego, que también se puede llamar cable no combustible con aislamiento mineral, este cable puede soportar entre 950 ° -1000 ° y puede funcionar durante 180 minutos a esta alta temperatura. Este tipo de cable se utiliza principalmente en...

Low-voltage power cable structure and the difference between four-core and five-core cables

图片
Low-voltage power cables are cables with a rated AC voltage of 1kV and below, which are used to transport electrical energy. In practical applications, there are many models of low-voltage cables, and it is very important to distinguish the various models. This article will introduce the basic meaning of low-voltage power cable models and their differentiation methods in detail.   A multi-core cable is a cable with more than one insulated core. Cables play an important role in electronic products and electronic systems, and are the key link to connect the various functions of electronic products, and are widely used in the fields of aerospace and aviation, as well as naval warships. Multi-core cables reduce the skin effect of the cable, thus reducing line losses. Power cables are cables used for the transmission and distribution of electrical energy. Power cables are commonly used in urban underground power grids, power station lead-in lines, internal power supply of industrial an...
