Why can't an underground system be operated above ground?
Understand the Problem
The question seems to imply an issue or inquiry regarding the operational constraints of an underground system and why it cannot function above ground. The focus appears to be on the limitations or reasons behind this operational restriction.
Answer
Insulation difficulties and heat dissipation issues.
The underground system cannot be operated above ground mainly due to insulation difficulties and heat dissipation issues.
Answer for screen readers
The underground system cannot be operated above ground mainly due to insulation difficulties and heat dissipation issues.
More Information
Underground systems require specific insulation to handle high voltages that is not suitable for above-ground conditions due to the potential for insulation failure. Moreover, the underground has challenges with heat dissipation due to lack of airflow which is more effective above ground.
Tips
A common mistake is assuming that underground systems can easily be adapted for above-ground use without considering insulation and heat dissipation requirements.
