"Asia Port" metal shielded power cable is made of high quality oxygen-free copper and environmentally friendly PVC. It has the characteristics of acid and alkali resistance, oil resistance, moisture resistance and mildew resistance. The product has the electrical characteristics of ordinary plastic cable and has strong anti-electromagnetic interference, anti-lightning performance and balanced potential, and improves the quality of power supply. It is especially suitable for places with sophisticated electronic devices, such as computer centers, aerospace control centers, and intelligent buildings. The shielded cable has the above-mentioned performance, and also has the function that the shielding layer can replace the grounding auxiliary line, and achieves the function of the secondary line, and achieves the resistance requirement of the secondary line conductor, and can be grounded and can replace the secondary line.
The basic task of routine maintenance of cable lines is to meet the needs of the grid and users for uninterrupted power supply, to prevent various cable accidents and to ensure safe power supply to the cable lines. The focus of routine maintenance work is to improve line power supply reliability, reduce cable accident rates, reduce power outage maintenance time, and reduce maintenance costs. Then the daily maintenance of the power cable line has the following three elements:
1. Inspection work of power cables. The patrol work can be divided into cycle patrol and state patrol. The daily inspection cycle is based on the results of the rating of the power cable equipment, and is divided into different cycles to conduct inspections. (The rating of power cable equipment refers to the rating of cable lines and their ancillary equipment. It is an important part of the safety inspection of power supply equipment and a basic work of power supply equipment management.) The normal cycle inspection work is to ensure the safety and reliability of power cables. The basic guarantee of operation. The power cable state patrol cycle is determined by the construction conditions around the power cable path, and the patrol cycle is variable from one day to one month. The state inspection cycle is a necessary guarantee to ensure the safe and reliable operation of the power cable.
2. Insulation supervision of power cables. At present, power cable insulation supervision mainly through the handover test and preventive test of high-voltage electrical equipment and comprehensive analysis of operation conditions. If insulation defects are found, first understand the insulation aging law and development trend to facilitate timely elimination of existing defects and maintain good insulation of equipment. Level.
3. Load monitoring of power cables. The daily load monitoring of power cables is an effective monitoring method. For some current heavy-duty cables, it is necessary to perform necessary auxiliary temperature measurement on the cables to ensure that the operating indexes of the operating cables are within the controllable range.China leading manufacturers and suppliers of Suzuki Brake Disc,FOR Suzuki Auto Brake Disc, and we are specialize inFOR Suzuki Car Brake Disc,FOR Suzuki Automobile Brake Disc, etc.
