The shape of the wires and cables is determined by different actual environment and special equipment. In daily life, in addition to circular cables, flat -shaped cables are actually very common. Do you know what the round cable is selected and the flat cable is selected? Round cables and flat cables are two common cable types. They have their own characteristics in structure, performance and application. TST Cables analyzes these two cables.
Circular cable
Round cables are one of the most common cable types. The cross section is round, consisting of one or more insulating conductors, and is usually wrapped in an external sheet.
Characteristics of circular cable structure
Deitors: usually made of copper or aluminum, and you can choose different cross -sectional areas as needed.
Insulation layer: There is a layer of insulation material around each conductor, such as PVC, XLPE (cross -linked polyethylene).
Handle layer: All insulating conductors are wrapped in an external sheet, and the protective cover material depends on the application of the cable.
Filling and reinforcement: In order to keep the cable round shape, some filling may be added inside; for cables that require additional mechanical strength, enhanced parts can also be added.
Round cable performance characteristics
Softness: Depending on the number and diameter of the conductor, the softness is different.
Environmental resistance: Depending on the gear materials, it has different performance of heat resistance, cold resistance, oil resistance, chemical corrosion resistance.
Working temperature range: Usually it can work within a wider temperature range, from -40 ° C to+100 ° C or even higher.
Electricity: It has good electrical performance, such as low capacitors, low resistance, etc.
Round cable usage scenario
Power transmission: used for high -voltage transmission lines, power distribution networks, etc.
Data transmission: used for local area networks, telephone lines, etc.
Control cable: for signal transmission in industrial automation systems.
Special applications: such as railway cables, medical cables, aviation cables, nuclear power stations, wind power cables, oil and gas cables, Automotive Cable, robotic cables, industrial cables, mining cables, marine cables, etc.
Flat cable (with -like cable)
Flat cables, also known as band -shaped cables or flexible cables, are a special cable type, and their cross sections are flat.
Flat cables (band -like cable) structural characteristics
Conduct: It is usually made of copper, and you can choose different cross -sectional areas as needed.
Insulation layer: There is a layer of insulation material around each conductor, such as PVC, rubber, etc.
Handle layer: All insulating conductors are wrapped in a flat outer sheath.
Fill: In order to maintain the flat shape of the cable, some filling may be added inside.
Performance characteristics of flat cables (with -like cables)
Softness: Flat cables have good softness, easy to bend and install.
Environmental resistance: Depending on the gear materials, it has different performance of heat resistance, cold resistance, oil resistance, chemical corrosion resistance.
Work temperature range: Usually it can work within a wider temperature range, from -40 ° C to+80 ° C or even higher.
Electricity: Even under extreme conditions, flat cables can maintain good electrical performance.
Flat cable (band -like cable) use scenarios
Mobile devices: suitable for equipment that requires frequent movement, such as cranes, elevators, driving, tower cranes, etc.
Interior application: suitable for connection between mobile mechanical components in the indoor environment.
Special environment: use in environments that need chemical corrosion, waterproof, oil -resistant, and wear -resistant environments.
Limited space: flat design makes it easier to install in places with limited space.
Comparison of the difference between circular cables and flat cables
What is the difference between the round cable and the flat cable? TST Cables analyzes from three dimensions, so that everyone can refer to the cable selection.
- In terms of physical performance
- Differences in appearance: The shape of the flat cable is flat, and the shape of the round cable is round. Therefore, it is easier to increase the tensile -resistant galvanized steel wire than the round cable.
- Differences in the internal arrangement of the cable: The internal conductor line of the flat cable is coexisted in accordance with uniform and orderly rules, mostly arranged or plum blossoms; and the internal conductor wire core of the circular cables is multi -twisted, which also determines that it also determines Circular cables are lower than the production cost of flat cables.
- Differences of physical properties: mainly reflected in bending and bending times. In the case of exactly the same number of conductors, compared with the circular cable, the bending range and bending times of flat cables are greater and the service life is longer.
- In terms of chemical performance
- Different heat dissipation: In the case of the same number of conductor lines, flat cables have advantages in heat dissipation than round cables.
- Different signal transmission directions: The circular structure has the symmetry of circular distribution. Whether it is a semi -dual -worker, the full dual -work transmission is relatively flat and only in one direction.
- Different signal shielding effects: The internal structure of the circular cable is easier to add shielding layer than flat cables, and the signal shielding effect is better.
Third, from product installation
- Payment: The flat cables cannot be shifted horizontally, and flat cables are saved and saved.
- Performance: Circular cables are more likely to wear tube in installation and are widely used.
- Special environment: Flat lines are generally used in specific environments, such as under the ground, the flat line will be better.
Suggestions for selecting circular cables or flat cables (band -shaped cables)
When choosing a cable, you need to consider factors such as specific application requirements, environmental conditions, and technical specifications of cables. For example: If you need a good soft, smaller bending radius, and limited space, flat cables may be a better choice. Instead, if the cable is required to have higher mechanical strength and wider environmental capacity, the circular cable may be more suitable. In the actual selection process, it is recommended to consult the cable engineer TST CABLES professional in order to obtain the most suitable solution.
