What must be done at the end of trolley and feeder wires?

At the end of trolley and feeder wires, it is essential that they are anchored securely and insulated. This practice is crucial for safety and operational integrity in mining environments. Anchoring wires securely ensures that they remain stable and do not move or sag, which could create hazards for workers and equipment. Additionally, insulating the wires prevents accidental electrical contact, which could lead to electrocution or equipment damage.

Proper insulation also guards against environmental factors that could degrade the wire over time, maintaining the effectiveness and safety of the electrical system. Therefore, securing and insulating these connections is a fundamental safety measure that protects workers while ensuring reliable operation of electrical systems in a mine.
