Applications
Airfield Lighting Equipment Primary cable for the serie circuit connecting the Constant Current Regulators and the isolating transformers, and between isolating transformers.
This cable can be directly buried in ground without mechanical protection, but keeping with common practices (sand bedding, warning grid...)
