ELEMENT 7.2 - HV CABLE HANDLING AND STRESS CONTROL
To achieve the lesson learning objectives, the participants can:
45) Explain the consequences of improper cable handling (Knowledge, intermediate level)
46) Explore different cable movements required to maintain the cable within specified bending radius limits (Knowledge, advanced level)
47) Choose proper cable handling methods to avoid stress-related damage (Knowledge, advanced level)
48) Explain correct transfer of load from pull to park (Knowledge, intermediate level)
49) Distinguish the need for additional cable socks under different working conditions (Skills, intermediate level)
The instructor shall:
Discuss with the participants proper HV cable handling and stress control techniques
Explain and illustrate techniques and good practices for safe transfer of load from pull to park:
a.
proper HV cable handling and stress control
b. moving and positioning the cable to avoid stress or damage
c.
bending Radius Limits
d.
avoiding damage to the termination
e.
never pull cable ends
f. consequences of improper handling, e.g. Partial Discharge (PD)
Illustrate a range of typical HV cable pulling scenarios to participants and quiz participants on safe approaches to transfer of load from pull to park
Ask open-ended questions about use of additional cable socks and explain when they could be required such as
a.
if max loading is exceeded
b.
moving cable in restrictive areas
c. placing cable into a specific position or configuration for securing the tower loop
