In this article, we will learn about the basic details of PSC (Prestressed Concrete) which are the electric poles used in LT (low tension) overhead distribution lines.
Types of PSC Poles
The following two types of PSC poles used in distribution lines:
- 8 Meter PSC Pole
- 9 Meter PSC Pole
The specifications of 8m and 9m PSC poles are given here.
8 Meter PSC Pole
The 8 m PSC pole is mainly used in 220 V or 400 V distribution lines.
