Factors affecting Aerial Bundled Cable (ABC) SANS 1418 Standard and placement in the wiring six factors affecting cable performance: Ultraviolet (UV)– Do not use cables without UV protection in direct sunlight. Heat — The temperature of the cable in the metal tube or groove is very high, and many polymeric materials will degrade their service … Read more
The rate of plastic extrusion According to the flow rate analysis of the viscous fluid in the material conveying and homogenizing section of the ABC conductor, the flow rate of the plastic (that is, the extrusion speed) is proportional to the screw speed, and the screw speed is an important operating variable to characterize the … Read more
Wire and cable in the process of operation, due to the existence of resistance will be heated.The resistance of the wire is generally very small, and its heating power can be expressed by the formula Q =I^2R.Q =I^2R indicates that: for a section of wire in use (R has been basically constant), the greater the … Read more
The operation of power cable lines is extremely important in the entire power production process. Because the safety of cable lines is directly related to the production safety of enterprises and the safety of people’s lives and properties, it is extremely important to understand the operation and maintenance of power cables and lines. Things. In … Read more
1. The basic requirements of high voltage cable head The cable terminal is the component that connects the aerial bundled cable(abc) with other electrical equipment. The cable middle is the component that connects the two cables. The cable terminal and the middle are collectively called cable accessories. The cable accessory should be able to operate … Read more
The biggest advantage of corrugated aluminum sheathed cross-linked cables is light weight and large short-circuit thermal stability. In a system with a slightly longer short-circuit current, the standard thickness of the aluminum sleeve can meet the requirements. For example, when the thermal stability is not enough in the calculation, the aluminum sleeve can be thicker … Read more
1. Inspection method Routine test: It is an experiment conducted by the manufacturer on all finished cables. Its purpose is to check whether the quality of the product meets the requirements of the technical conditions in order to find accidental defects in the manufacturing process. It is a non-destructive experiment, such as the DC resistance … Read more
1. Ointment. The ointment mainly includes fiber paste and aerial bundled cable(abc) 7870. Under normal circumstances, the fiber paste should fill the entire loose tube, and the cable paste should fill every gap of the optical cable core under pressure. Nowadays, there are ways to fill the fiber paste half full or less. For the … Read more
