The user of underground cables is provided with information on the design, testing, and application of moisture-impervious, medium-voltage, solid dielectric power cable using metal-plastic laminates as moisture barriers. Information is also provided on selection of jacketing materials and installation practices. Other types of moisture barriers, such as extruded metal sheaths and bare metallic tapes with sealed seams, are beyond the scope of this guide.

This guide will provide the user of underground cables with information on the design, testing, and application of moisture-impervious, medium-voltage, solid dielectric power cable using metal-plastic laminates as moisture barriers. References will be found in clause . A complete bibliography of pertinent technical papers together with patent and specification references relating to the content of this guide will be found in clause . The annexes provide information selection of jacketing materials and installation practices. It is recognized that there are other types of moisture barriers available, such as extruded metal sheaths and bare metallic tapes with sealed seams (referred to in ), that are beyond the scope of this guide. This guide should not be interpreted as precluding their use.
