Chemical-moisture barrier cable-concept and practice

Cables with sheaths providing protection from chemicals and moisture have gained in popularity among many industrial and utility users in North America and Europe. These sheaths are used to protect low-, medium-, and high-voltage power cables as well as fiber-optic and instrumentation cables. This paper presents an overview of the theory, design, testing, and field experience for each type of cable as it pertains to chemical and moisture protection. Documentation is provided covering underground installations of chemical-moisture barrier cable in a large petrochemical manufacturing facility located on the Texas Gulf Coast.
