These parameters are used to calculate voltage drop, determine current carrying capacity, and select protective equipment. The load capacity of the line is also evaluated based on this reference table.
Since selecting incorrect cross-sectional areas leads to overload or cost waste, engineers need to accurately reference these specifications to ensure safe operation.
4. Applications and Ngoc Lan Cable products
After mastering the technical specifications, let's explore the practical applications of aluminum aerial bundled cables applying TCVN 6447 standard in electrical power projects.
Aluminum aerial bundled cables according to TCVN 6447 are primarily applied in electrical distribution systems such as:
- Low voltage electrical networks in urban areas – using cables with cross-sectional areas from 25mm² to 70mm²
- Electrical projects in rural areas – prioritizing cross-sectional areas of 16mm² and 25mm²
- Power supply for industrial clusters – commonly selecting large cross-sectional areas from 95mm² and above
To gain deeper understanding of structure and material characteristics that help optimize selection, detailed study of ABC cables will provide the specialized knowledge necessary for engineers during design and practical application processes.
5. Frequently asked questions about TCVN 6447
From deployment experience in various projects, several technical questions are commonly raised by specialists. This section addresses common concerns based on practical experience.
Check the certification documents with valid expiration dates. Measure actual cross-sectional area and compare with standard reference tables. Poor quality cables typically have cross-sectional areas 10-15% smaller than declared specifications. Check insulation thickness using calipers. TCVN 6447 is a standard specifically for low voltage aluminum aerial bundled cables (LV-ABC), voltage rating 0.6/1kV. IEC 60502 is a standard applied to power cables with extruded insulation and accessories for rated voltages from 1kV to 30kV.5.1. How to verify cables meet TCVN 6447 standard?
