CHEMICAL-MOISTURE BARRIER CABLE CONCEPT AND PRACTICE

Cables with sheaths providing protection from chemicals and moisture h ave gained in popularity among many industrial and utility users in No rth America and Europe. These sheaths are used to protect low-, medium -, and high-voltage power cables as well as fiber-optic and instrument ation cables. This paper presents an overview of the theory, design, t esting, and field experience for each type cable as it pertains to che mical and moisture protection. Documentation is provided covering unde rground installations of chemical-moisture barrier cable in a large pe trochemical manufacturing facility located on the Texas Gulf Coast.
