Định mức 203/QĐ-EVN

(Decision 203/QD-EVN) refers to a regulatory document issued by Vietnam Electricity (EVN) that establishes technical and economic norms, primarily for labor and operation within the power sector. Key Content Overview

The PDF version is preferred because it retains the original formatting of tables—specifically Bảng 4.1 (excavation), Bảng 7.1 (pole erection), and Bảng 8.3 (wire pulling).

• Norm: residential 200 kWh/month per household (example).
• Actual measured monthly: 260 kWh → 30% above norm.
• Action: audit for inefficiencies (lighting, appliances) and offer targeted subsidy or tariff adjustment.

2. The "Invisible" Savings

: 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

Safety and Environmental Standards

: Guidelines to ensure that all operations are conducted safely and with a minimal environmental impact. This might cover everything from personal protective equipment for workers to environmental assessments for new projects.

1. Identify the Work Type: Is it "Underground cable construction" or "Aerial bundle cable?"
2. Look up the Voltage Level: Navigate to Table 3.1 (110kV) vs. Table 4.2 (0.4kV).
3. Apply the Coefficient: The PDF often includes regional coefficients (K1 for urban, K2 for rural, K3 for high altitude).
4. Calculate Total Quota: Multiply the base norm by the coefficient and your project length.
