CHARACTERISTICS OF UNDERGROUND PRIMARY CABLE
For all employees
To efﬁciently size underground cables, one must ﬁ rst understand the physical structure of the conductors, and the function of the components of the underground cable. Understanding the function and limitation of each layer of the underground cables enables the designer to more efﬁ ciently design underground distribution lines.
- The layers of primary conductors, their function and limitations
- Practical application of conductors, based on material make-up (aluminum vs. copper) and conﬁ guration (stranded core vs. solid core)
- Types of conductor shields, their purpose and effectiveness
- Electrical characteristics of underground cables, capacitive reactance and dielectric loss
