Features

01

Excellent anti-interference performance

Shielding structure: In order to reduce mutual crosstalk and external interference between loops, computer cables generally adopt shielding structure. Common ones are sub-shielding (shielding each pair of cores) and total shielding (shielding all cores as a whole), and even a combination of sub-shielding and total shielding. This multi-layer shielding structure can effectively block external electromagnetic signal interference and ensure the purity of the signal inside the cable. For example, in industrial environments with strong electromagnetic equipment such as large motors and transformers, the shielding structure of computer cables can ensure stable signal transmission.

Good insulation performance: The quality of insulating materials is crucial for anti-interference ability. Computer cables usually use insulating materials with small dielectric constant and low dielectric loss, such as polyethylene, which can not only reduce the energy loss of signals during transmission, but also reduce signal interference caused by the characteristics of the insulating materials themselves.

02

Reliable transmission performance

High bandwidth and high speed: It can support high-bandwidth data transmission and meet the needs of computer systems and automated instruments for rapid transmission of large amounts of data. Whether it is high-definition images, audio files, or complex program codes, data can be accurately transmitted in a short time.

Strong weak signal transmission capability: Computer cables can also reliably transmit some weak analog signals. This is very important for automated instruments that require precise measurement and control, and can ensure that the equipment obtains accurate signal information, thereby achieving precise control and monitoring.

03

Stable electrical performance

Adapt to different environments: The electrical performance of computer cables can remain relatively stable under different environmental conditions such as temperature and humidity. Whether in hot summer, cold winter, or humid environment, it can work normally to ensure stable signal transmission.

Good voltage resistance: The cable has a high voltage resistance between the core and the core and between the shields, and can withstand certain voltage fluctuations and instantaneous overvoltages, ensuring that the cable will not be broken down when abnormal conditions occur in the power system to ensure the safe operation of the equipment.

04

Flexible mechanical properties

Good flexibility: Generally has good flexibility, which is convenient for wiring and laying in different installation environments. For example, in complex environments such as narrow spaces and curved pipes, computer cables can be easily bent and installed, reducing the difficulty and cost of installation.
