Asian port metal shielded power cable has excellent anti-electromagnetic interference performance
"Asia Port" metal-shielded power cables are manufactured using high-quality oxygen-free copper and environmentally friendly PVC. These cables exhibit excellent resistance to acids, alkalis, oils, moisture, and mold. In addition to the standard electrical properties of conventional plastic cables, they offer strong electromagnetic interference (EMI) shielding, lightning protection, and balanced voltage performance, which significantly enhance the quality of power supply. They are particularly suitable for environments with advanced electronic equipment, such as computer centers, aerospace control systems, and smart buildings. The shielding layer not only provides effective electromagnetic protection but can also serve as a grounding auxiliary line, fulfilling the function of a secondary circuit while meeting the resistance requirements of the secondary conductor. This dual functionality allows for simplified installation and improved system reliability.
The primary goal of routine maintenance for cable lines is to ensure a continuous and stable power supply that meets the needs of both the grid and end-users. It aims to prevent various cable-related incidents and guarantee the safe operation of the cable system. The main focus of routine maintenance is to improve the reliability of power supply, reduce the frequency of cable failures, minimize power outage times, and lower maintenance costs. Daily maintenance of power cable lines typically involves three key elements:
1. **Inspection of Power Cables**: Patrol activities can be categorized into scheduled patrols and condition-based patrols. The frequency of daily inspections is determined by the rating of the cable equipment, which includes both the cable lines and their associated components. This rating is a crucial part of safety inspections and an essential aspect of power equipment management. Regular scheduled patrols ensure the safety and reliability of the cables, forming the foundation of their safe operation. Condition-based patrols, on the other hand, are adjusted based on the surrounding conditions of the cable route, with intervals ranging from one day to one month. These patrols are essential for maintaining the safe and reliable operation of the cables.
2. **Insulation Monitoring**: Insulation supervision of power cables is primarily conducted through handover tests and preventive tests of high-voltage electrical equipment, combined with comprehensive analysis of operational conditions. If insulation defects are detected, it is important to understand the aging patterns and development trends of the insulation to address existing issues promptly and maintain the equipment's insulation performance at an optimal level.
3. **Load Monitoring**: Monitoring the load on power cables on a daily basis is an effective method for ensuring safe operation. For cables that operate under heavy loads, it is necessary to perform temperature measurements as an additional check to ensure that the operating parameters remain within acceptable limits. This helps prevent overheating and potential failures, contributing to the overall stability and longevity of the power system.
