423-01 Introduction to Medium Voltage Cable

When you complete this lesson, you will be able to identify the components of medium voltage cable and why each is needed.

• Relate the difference in “pressure” between low voltage and medium voltage
• Describe corona
• Describe partial discharge
• Describe conductor stranding
• Identify the strand shielding
• Describe conductor insulation
• Describe insulation stranding

423-02 Medium Voltage Splices and Terminations

When you complete this lesson, you will know the steps needed to splice and terminate medium voltage power cable.

• Explain why a splice may be needed
• Describe the first step in cable preparation
• Describe the layers that need to be removed to prepare for a splice
• Describe the steps of re-shielding and re-insulation
• Describe the steps in preparing for cable termination
• Explain what is needed for a Class One termination
• Explain where stress control is needed in the termination
