This article provides a comprehensive reference source including:
- Standard information table on validity and equivalent national standards
- Technical specifications for quick reference
- Official and free TCVN 8090 PDF download documents
Let's explore from general information overview, then delve into technical specifications and practical applications in modern electrical power projects.
1. General introduction to TCVN 8090
What is TCVN 8090 standard? This is a national technical regulation for bare conductors used in overhead power transmission lines, replacing the previous TCVN 5064 standard. The standard specifies the structure of bare conductors with shaped wires stranded into concentric layers.
This standard is equivalent to IEC 62219. This equivalence ensures that Vietnamese products meet international quality standards. Manufacturers like Ngoc Lan Cable strictly comply to ensure product quality meets export standards.
Lack of understanding about TCVN 8090 standard can lead to errors in the bare conductor manufacturing process. The consequence is that project quality is affected and operating costs increase significantly. Therefore, electrical engineers need to master this standard to ensure safety and efficiency for the power grid system.
2. Main information table of TCVN 8090 standard
The table below summarizes data about TCVN 8090. This helps electrical engineers quickly reference information during work, saving considerable time when consultation is needed.
| Category | Information |
|---|---|
| Full name | TCVN 8090:2009 – Bare conductors for overhead power transmission lines – Bare conductors with shaped wires stranded into concentric layers |
| Year of promulgation | 2009 |
| Validity status | Still in effect |
| Replaced standard | Replaces TCVN 5064:1994 |
| Equivalent international standard | IEC 62219:2002 |
| Issuing authority | Ministry of science and technology |
