What is the difference between wires and cables?

Wires and cables play a vital role in house decoration, construction site construction, line transmission and other places of production and life, but are you overwhelmed by the many choices of wires and cables? Don't just wait and see, this blog post will bring you better options and insight into the product itself. We will not only introduce overhead transmission wires with simple structure, but also introduce all the contents of more professional types of insulated cables.

Difference Between Wire and Cable 

The main difference between wire and cable is that a wire is a single conductor while a cable is a set of conductors. Usually the wires are bare and twisted, but some wires have a layer of PVC insulation on the outside. The cables are run in parallel and are twisted or glued together to form a single container with an inner and outer sheath for safety purposes.


1. The difference of materials

The difference between wires and cables is that wires are generally smaller in size and simpler in structure, but sometimes cables are also classified into generalized wires.
Wire Conductive metal wire used to carry electric current. Available in solid, stranded or braided forms. According to the insulation condition, it is divided into two categories: bare wire and insulated wire.
The cable consists of one or more insulated conductors with mutually insulated wire cores placed in a closed sheath, and a protective covering can be added to the outside.


2. The difference in use

Bare conductors(wires) refer to products with only conductors and no insulating layer. The conductors are copper, aluminum, various metals, or composite metal round single wires, and various shapes of wires such as twisted wires and flexible wires are used for overhead. power transmission. Different conductor materials are used for different spans and ability to withstand breaking strength. Insulated wires are mainly used for household appliances and small motor tools, various instruments, electric lighting devices, and the rated AC voltage is below 450/750V.
Cables include cross-linked polyethylene insulated power cables and polyvinyl chloride insulated power cables, which are mainly used for transmission, distribution of electrical energy or transmission of electrical signals.

3.The structure is different

The main difference between power cables and ordinary wires is that the cables are larger in size and more complex in structure. The cable is composed of a conductive core, an insulating layer, a shielding layer and a protective layer. The conductive core is the main part of the power cable and is used as a conductive part to transmit electrical energy. The insulating layer plays the role of electrically isolating the ground and the wire core while ensuring the transmission of electric energy. The protective layer is to protect the power cable from the intrusion of external impurities and moisture, and prevent the external force from directly damaging the power cable.


4.The hardness is also different

When choosing a wire, the hardness is not as high as that of the cable, and it is relatively soft, because its power and current carrying capacity are not very good.

What to pay attention to when purchasing wires?

1. Load capacity

The power consumption of a family changes every moment. If the power consumption is large, TV, air conditioner, computer, desk lamp, water purifier, refrigerator, hair dryer, etc. can be used together. If the load capacity of the wire is not strong and the weather is hot in summer, the power supply with overloaded wire may generate heat, causing serious consequences such as fire.


2. Waterproof

Some wires are not tightly packaged and easily deformed and cracked. If it breaks and leaks, it may cause short circuit, short circuit, fire and personal injury. Therefore, the wire should choose a hard sheath and good waterproof performance.

3. Conductivity

There are copper core and other wires on the market. Copper core wire is the most practical interior decoration. However, copper core wire is divided into several types, including large radius copper core and multi-wire copper core.


4. The main line should have a thick core

Power is the two main wires that go from the mains to all the devices. The main line must use thick copper core wire, because it carries the charge of each electrical appliance, it needs thick copper wire with good performance.


5. Length

There are many unscrupulous traders cheating on the length of the wire, the wire has a meter mark, but some profiteers underestimated the 10 meters in the middle of the wire. For example, after 30 meters it will start to display 40 meters.
