Ensuring safety and compliance with regulations are crucial during cable construction. Due to their different functions and application environments, strong and weak electrical cables need to comply with different specifications and operating guidelines during construction. The Pearl River Cable summarizes the key points of these two types of cables in construction, emphasizes the importance of safe construction, and ensures the long-term stable operation of cables. 

Construction specifications and operation guidelines for high-voltage cables

Strong current cables are mainly used to transmit high voltages and currents, and their construction process requires extremely high safety and standardization requirements. Firstly, detailed planning should be carried out based on the design drawings of the power system before construction, clarifying the cable laying path, wiring method, and protection measures. Ensure that the cables, insulation materials, connectors, etc. used comply with national and industry standards and have qualified quality.

During the construction process, strong electrical cables should be buried underground or laid in dedicated cable trays as much as possible to avoid external damage. During the laying process, it is necessary to avoid the cable bending radius being too small to prevent the cable core wire from breaking. High voltage cables need to be equipped with reliable grounding devices to ensure that leakage current can be quickly discharged in abnormal situations and prevent electric shock accidents. Warning signs and isolation fences should be set up on the construction site, and non construction personnel are not allowed to enter the construction area to ensure safety.

Construction specifications and operation guidelines for weak current cables

Weak current cables are used for the transmission of low voltage and low current signals, and special attention should be paid to the integrity and anti-interference ability of the signals during the construction process. According to the design requirements of building intelligent systems and communication systems, conduct detailed cable routing planning and determine reasonable routing paths. Ensure that the cables, connectors, and shielding materials used comply with standards and have good signal transmission performance and anti-interference ability.

Weak current cables should avoid parallel wiring with strong current cables, and shielding pipes or isolation measures should be used if necessary to reduce electromagnetic interference. During the laying process, mechanical damage to the cables should be avoided, and each cable should be clearly labeled for easy maintenance and management. Use professional connectors for cable connections to ensure the stability and reliability of signal transmission. The connection needs to be shielded to prevent signal leakage and interference. Cables that may be subject to electromagnetic interference need to be shielded using metal shielding layers or shielded pipelines to ensure the integrity of signal transmission.

In summary, there is a significant difference in the adaptability of strong and weak electrical cables to different working environments, which determines their specific requirements and performance in different application scenarios. Reasonably selecting and using different types of cables to ensure the safety and stability of electrical and signal transmission systems is the key to achieving efficient operation.
