3.0.2 In addition to this code, the design of heavy icing lines shall observe the requirements as specified in Code for Design of 110kV-750kV Overhead Transmission Line.
3.0.3 When designing heavy icing lines, the measures for avoiding icing or anti-icing shall be given priority. In areas where conditions permit, the measures for melting and preventing icing may be used if justified through technical and economic comparison. For the lines designed with ice melting and prevention measures, design ice thickness shall be selected appropriately to ensure that they have a certain anti-icing capability.
3.0.4 In parallel with the design of heavy icing lines, ice observation stations (points) shall be established and on-line icing monitoring shall be conducted for transmission lines if conditions permit so as to collect the data at ice observation stations and summarize the design and operation experiences.
3.0.5 For the purpose of this code, transmission lines are divided into three categories in terms of voltage levels.
Category 1: lines operating at 750kV, 500kV, and critical lines operating at 330kV;
Category 2: lines operating at 330kV, and critical lines operating at 220kV;
Category 3: lines operating at 220kV and 110kV.

3.0.6 The specific tasks of designing an electric power system are to:
1 Analyze and propose the level, distribution, composition and characteristics of the electric power demand.
2 Balance the electric power and energy, and further demonstrate the reasonable range served by the power system and associated networking schemes, power source building schemes as well as system peak regulation scheme.
3 Demonstrate the grid construction schemes, including voltage level, grid structure, and transitional measures.
4 Carry out electrical calculation on the power grid, and then propose the technical measures for ensuring voltage quality and safety and stability of the system.
5 Propose the commissioning time of power generation,transmission and transformation projects and reactive power supply,quantity and main specifications of major equipment, and perform investment estimation.
6 Propose the special topics requiring further study.
