Product Description

Product Description
 

General Overview

 
Computer cables are mainly used for signal transmission in electronic computer systems and automated control systems, as well as for electrical connections between testing instruments, meters and other equipment. They can ensure the accuracy, stability and reliability of signal transmission in complex electromagnetic environments.

Structural Characteristics

 
  1. Conductor
    Typically, high-purity oxygen-free copper is used as the conductor material. Oxygen-free copper has good electrical conductivity and can effectively reduce signal loss during transmission. For example, its electrical conductivity can reach more than 100% IACS (International Annealed Copper Standard), ensuring that the electric current can flow smoothly and thus guaranteeing signal quality. The conductor core specifications are diverse and can be selected according to specific current-carrying requirements and signal transmission bandwidth. Common core cross-sectional areas range from 0.5mm² to 2.5mm².
  2. Insulation
    In DJYVP, the "J" stands for polyethylene (PE) insulation. Polyethylene is an excellent insulating material with a very high insulation resistance, generally reaching above 10¹Ω·m. This enables the cable to effectively isolate the current between conductors and prevent signal crosstalk. Meanwhile, the dielectric constant of polyethylene is relatively stable, and it can maintain good insulating performance for signals within a wide range of temperatures and frequencies, ensuring the integrity of signal transmission. Moreover, it has chemical resistance and can resist the erosion of certain acids, alkalis and other chemical substances.
  3. Shield
    The "Y" indicates copper wire braided shielding. The copper wire braided shielding layer is an important part of computer cables. It can effectively prevent external electromagnetic interference (EMI) from entering the cable interior and also prevent the signals inside the cable from radiating outward. The coverage rate of copper wire braiding is generally around 80% - 90%. For example, in some industrial environments where there are a large number of motors, frequency converters and other equipment generating electromagnetic interference, this high-coverage copper wire braided shielding can significantly reduce the impact of interference signals on computer signal transmission and ensure the accuracy of data transmission.
  4. Jacket
    The final "P" stands for polyvinyl chloride (PVC) jacket. The PVC jacket provides physical protection for the cable. It has good wear resistance, weather resistance and flexibility. During installation and use, it can withstand a certain degree of stretching, bending and friction. For example, when the cable is laid through cable trays, pipes or needs to be bent during equipment connection, the PVC jacket can prevent the internal insulation layer and conductors from being damaged and extend the service life of the cable. Moreover, the PVC jacket can also play a certain role in flame retardancy. When encountering a fire source, it can delay the spread of the fire and improve the safety of the cable.

Electrical Performance

 
  1. Rated Voltage
    The rated voltage of computer cables usually has specifications such as 300/500V. This means that the cable can safely transmit signals in power systems with a phase voltage of 300V and a line voltage of 500V, providing stable electrical connections for computer equipment and related control systems and meeting the voltage requirements of most computer systems and automated control scenarios.
  2. Transmission Characteristics
    It has good signal transmission characteristics, and its bandwidth can meet various computer signal transmission standards. For example, for common digital signal transmission, it can support high-speed data transmission rates such as 100Mbps, 1Gbps or even higher, and can be used to transmit various types of signals such as computer network signals (such as Ethernet signals), control signals (such as RS - 485, RS - 232 signals), etc. Moreover, the signal attenuation is small, ensuring the effective transmission of signals over relatively long distances (such as several hundred meters).

Working Environmental Conditions

 
  1. Temperature Range
    It can work normally within a relatively wide temperature range. Generally speaking, its working temperature range can be from - 20°C to 70°C. In low-temperature environments, such as some industrial cold storage warehouses or cold outdoor environments, the cable can still maintain its flexibility and electrical performance, and will not cause conductor breakage or a decline in insulation performance due to the hardening of materials. In high-temperature environments, such as in high-temperature workshops of factories or areas close to heating equipment, the cable can also work normally to ensure that signal transmission is not affected.
  2. Humidity Conditions
    It has a certain tolerance to humidity. It can work in environments with relatively high humidity. For example, in humid environments where the relative humidity reaches above 90%, its insulation and shielding performances will not decline significantly due to moisture absorption, thus ensuring the reliable operation of computer systems and automated control systems in humid environments.

     
    Product Parameters

    1. Conductor Parameters


    Material: High-purity oxygen-free copper is mostly used to ensure good electrical conductivity and signal transmission performance. Its purity usually reaches 99.95% or above. Core Specifications: The common nominal cross-sectional areas of the core include 0.5mm², 0.75mm², 1.0mm², 1.5mm², 2.5mm², etc. Different cross-sectional sizes can carry different magnitudes of current and are suitable for signal transmission with different bandwidth requirements. For example, in scenarios where the transmission distance is short and the signal rate requirement is not high, a 0.5mm² core may be sufficient; while for long-distance and high-speed data transmission, a 1.5mm² or 2.5mm² core may be selected. Number of Cores: The number of cores varies, ranging from 2 cores to dozens of cores. Commonly seen ones include 4 cores, 8 cores, 12 cores, 24 cores, etc. It depends on the actual number of signals that need to be transmitted and the functional configuration in practical applications. For example, for a simple connection between a computer and a printer, a 2-core or 4-core cable may be sufficient, while in a complex automated control system, dozens of cores may be needed to transmit multiple control signals, power signals, etc.

     

    6. Environmental Adaptability Parameters


    Working Temperature Range: It is generally between - 20°C and 70°C, which means that the cable can work normally within this temperature range and maintain stable performance. It can be applied in both cold outdoor environments and high-temperature indoor industrial sites. Moisture Resistance: In humid environments where the relative humidity reaches 90% or even higher, the cable should still be able to maintain its insulation, shielding and transmission performances and will not experience a decline in electrical performance or intensified signal interference due to moisture absorption. Corrosion Resistance: The overall structure of the cable should have a certain ability to resist chemical corrosion and be able to resist the erosion of common chemical substances such as acids and alkalis, ensuring long-term and reliable use in environments where there may be chemical pollution.

    5. Electrical Performance Parameters


    Rated Voltage: Common specifications include 300/500V, 450/750V, etc. They determine the voltage range of the power system in which the cable can be safely applied, ensuring stable signal transmission under the corresponding voltage and avoiding electrical failures such as insulation breakdown. Withstand Voltage: It is required to pass the specified withstand voltage test. For example, for a cable with a rated voltage of 300/500V, it usually needs to withstand an alternating current withstand voltage test (AC Withstand Voltage Test) of about 2000V - 2500V for about 1 minute to verify the insulation strength and withstand voltage ability of the cable. Transmission Rate: Different types of computer cables can support different transmission rates. For example, for general Ethernet applications, they can meet the rate requirements of 10Mbps, 100Mbps, 1Gbps, etc. It depends on factors such as the structure, material and bandwidth of the cable to ensure that signals can be accurately transmitted at the corresponding rates within the specified distance.
    • Jacket Thickness: It is usually around 0.6mm - 1.5mm, which is determined according to factors such as the outer diameter of the cable and the usage environment. A thicker jacket can better resist external physical damage, but it will also increase the weight and cost of the cable.

    4. Jacket Parameters


    Jacket Material: Polyvinyl chloride (PVC) is one of the commonly used jacket materials. Other materials such as low-smoke halogen-free polyolefin (LSZH) are also selected according to different application scenarios. The PVC jacket has good flexibility, wear resistance and weather resistance; while the LSZH material has the characteristic of producing less toxic smoke when burning and is often used in places with higher requirements for fire safety.

    3. Shielding Parameters


    Shielding Type: Common shielding types include copper wire braided shielding, aluminum foil shielding, and composite shielding combining copper wire braided and aluminum foil shielding. The braiding density of copper wire braided shielding is usually between 80% and 90%. For aluminum foil shielding, the integrity of the shielding layer coverage is generally required to be good. Composite shielding combines the advantages of both and can provide stronger protection against electromagnetic interference. Shielding Effect: Measured by shielding effectiveness, it is generally required that the shielding effectiveness reaches above 60dB - 90dB within a certain frequency range (such as 10kHz - 1GHz), which can effectively block external electromagnetic interference from entering the cable interior and suppress the radiation of signals inside the cable to the outside.

    2. Insulation Parameters


    Insulation Material: As mentioned before, polyethylene (PE) is used for insulation. Its insulation resistance is generally required to be no less than 10¹Ω·m to ensure a good insulation effect and prevent mutual interference between signals. Insulation Thickness: It varies according to different voltage levels and core specifications, usually around 0.2mm - 0.8mm. A thicker insulation layer can provide better protection in high-voltage application scenarios or environments with higher insulation requirements, but it will also increase the outer diameter of the cable.
