Qd-evn Pdf | Dinh Muc 203
The "Định mức 203" (Norm 203) refers to Quyết định 203/QĐ-EVN , which is a specialized technical document issued by Vietnam Electricity (EVN) . This document establishes the labor and technical norms
for the maintenance, repair, and operation of electrical equipment, specifically focusing on insulators and related hardware in the power grid. Core Content of Norm 203/QĐ-EVN According to the document details found on platforms like , the norm provides standardized calculations for: Insulator Replacement
: It sets labor coefficients for replacing various types of insulators (e.g., suspension or tension insulators) based on their weight (typically around 5kg to 7kg per unit) Maintenance Procedures
: Detailed steps for inspecting, cleaning, and treating rust on hardware like bolts, flanges, and anchor wires Labor Adjustment Coefficients Height Factors
: Adjustments for working at different heights on power poles. Special Terrain
: Multipliers (e.g., a coefficient of 2.0) for labor costs when working on high-voltage spans or difficult crossing sections Materials and Tools
: Lists the specific requirements for anti-corrosion paints (typically 1 primer layer and 2 color layers) and specialized tools needed for grid maintenance How to Use the PDF Guide dinh Muc 203 Qd-evn Pdf
When reviewing the PDF, you should focus on several key sections to ensure accurate cost estimation or project planning: Work Descriptions (Nội dung công việc)
: Always check the specific breakdown of tasks (e.g., "tháo cách điện," "vệ sinh," "sơn") to ensure all manual labor steps are accounted for Application Units (Quy định áp dụng)
: Identify the units of measurement used for the norms (e.g., per insulator string, per kilometer, or per pole). Notes and Multipliers (Ghi chú/Hệ số)
: Look for footnotes that modify the base labor rate based on environmental conditions or technical complexity Where to Find the Document
As this is an internal regulatory document, it is often distributed through EVN's internal portal or professional engineering libraries. Publicly accessible versions can sometimes be found on document-sharing sites like or specialized Vietnamese engineering forums. labor coefficients

3. Engineering Meets Accountability
Perhaps the most fascinating aspect of the Định mức 203 QĐ-EVN PDF is its role in accountability. It transforms vague concepts of "hard work" into measurable data.
The document details specific labor coefficients. For example, it defines the difference in effort required to work on a pole with concrete structures versus a suspension clamp. It accounts for the difficulty of terrain—whether the line is crossing a river or running through a dense urban area.
This level of detail ensures that procurement processes are transparent. It prevents corruption and waste by setting a hard ceiling on what constitutes a "reasonable" expense for any given technical operation. DM 1320: Digging pits for concrete poles (soft
Part II: System of Norms (The Tables)

1. What is it?
- Full name (Vietnamese): Quyết định 203/QĐ-EVN về việc ban hành định mức kinh tế - kỹ thuật cho lưới điện phân phối.
- Issuer: EVN (Vietnam Electricity)
- Purpose: Sets norms for labor, materials, costs, and technical standards in operating, maintaining, and repairing distribution networks (0.4kV to 35kV).
3. Labor and Maintenance Norms (Định mức lao động)
The PDF includes time-based norms for repair and maintenance tasks. For instance, it defines how many worker-hours are required to replace a blown fuse on a 22kV line or restring a conductor after a storm. This is essential for calculating the cost of service restoration.
