High Voltage Transmission Line
High Voltage Transmission Line’s overall structure from the inside to the outside of the components includes: conductor, insulation, inner sheath, filler (armored), outer insulation, the voltage level of 35 kilovolts or more, but more than 220 kilovolts can be regarded as ultra-high-voltage cables as well as ultra-high-voltage and so on.

Selecting a Power Cable
Different kinds of HV cable constructions are required to transport electrical energy from the power station to the consumer. High-voltage cables must be rigorously selected for their insulation when buried in the ground. The following factors are important when selecting a suitable cable construction:
- Maximum operating voltage
- Insulation level
- Frequency
- Load carried
- Daily load curve
- Magnitude and duration of possible overload currents phase-to-phase and phase-to-earth
- Connection between overhead and cable line (direct connection or via transformer)
- Insulation level of equipment (bare conductor insulators, arresters, etc.)
- Voltage drop
- Length of line
- Profile of line
- Mode of installation:
– underground (ducted or non-ducted)
– overground (if in a tunnel, the dimensions and mode of ventilation of the tunnel) - Chemical and physical properties of the soil:
– whether rocky, sandy, clayey, or boggy; moist or dry
– chemical agents liable to cause corrosion etc.
– maximum thermal resistivity of the soil - Maximum and minimum ambient air and soil temperatures, taking into account adjacent hot-water pipes and other factors liable to heat the cables
- Specifications and requirements that apply
- The cable should be economical to use; an optimum cross-sectional area can be calculated based on the capital costs of the cable and running costs incurred by the power losses in the cable.
