When laying out the high voltage cable as it is coming off the cable reel pallet assembly how much additional cable should you pull out beyond its expected final position for installing elbow and cabl?
10 feet
Who was the man responsible for laying the second and much improved telegraph cable under that Atlantic Ocean?
Lane Johnson
Formula for working out cable size?
There is actually no specific formula used to work out cable size. In order to determine the type of cable you need and the size you need, you need to know the source of the supply, the voltage of the system, the ambient temperature, and the method you plan on laying out the cable.
What is high tension cable?
cable that has high tension meaning high voltage.High Tension cable manufacturing technology is complete with heavy duty machines for wire drawing and conductor making, laying up, armouring , sheathing and packing.
What problems should be paid attention to when laying photovoltaic cables?
Cable laying The cable laying method is comprehensively considered according to factors such as engineering conditions, environmental conditions, and cable specifications, models, and quantities. The selection of the cable needs to be selected according to the principle of satisfying the requirements of reliable operation, easy maintenance, and reasonable technology and economy. There is little difference between the laying of AC cables and the laying of general power systems. DC cables are mostly used between photovoltaic modules, between strings and DC combiner boxes, and between combiner boxes and inverters. The cross-sectional area is small and the number is large. Generally, the cables are bundled along with the module brackets or laid directly through pipes. , DC cables generally need to be considered when laying: Connecting cables between components and connecting cables between strings and combiner boxes. As far as possible, use component brackets as channel support and fixation for cable laying, which can reduce the effect of environmental factors to a certain extent. The force of the cable laying should be even and appropriate, and not too tight. The temperature difference between day and night is generally large in the photovoltaic site, and thermal expansion and contraction should be avoided to cause the cable to break. For the cable leads of photovoltaic materials on the surface of the building, the overall aesthetics of the building should be considered. The laying position should avoid laying the cables on the sharp edges of the walls and brackets to avoid cutting, abrading, and damaging the insulation layer and causing short circuits or cutting the wires by shearing force. Cause an open circuit. At the same time, it is necessary to consider issues such as direct lightning strikes on the cable line. Reasonably plan the cable laying path, reduce the crossing, and combine the laying as much as possible to reduce the amount of earth excavation and the number of cables during the construction of the project. Cable construction costs in photovoltaic power generation projects are generally relatively large, and the choice of laying methods directly affects the construction costs. Therefore, reasonable planning and the correct selection of cables are important aspects of photovoltaic construction. KUKA CABLE through in-depth research on the laying environment, technical parameters, application occasions, etc. of cables for photovoltaic power generation systems, provides system selection and optimization schemes and conducts research and development and design of new products to create a complete building/water surface/centralized photovoltaic The overall product solution.
How can you lay earthing strip on cable tray?
no use laying an earthing strip in a cable tray better tap both the ends of the earthing wire to the trunking,it will save your wire also,or lay out a cable in the other trunking where you have low voltage wire running in.
What is the depth of underground cable system for HV cables?
It varies depending on the country your in, the voltage of the cable and the type of soil. Also if there is anything on the surface above the cable, railway lines for example. Another important thing to remember is that not all 'time-is-money' cable laying crews follow the rules. From experience, they are almost always too shallow. Scary!
