Maintenance and inspection of service grip dead ends
Conduct regular maintenance and inspection of the dead ends. This is to ensure their continued performance and safety. This also helps to identify and address potential issues before they become safety hazards or lead to system failure. These practices help ensure the reliability and longevity of the overhead conductor and cable systems. The following is a basic guide to the maintenance and inspection of service grip dead ends.
- Create a maintenance schedule including routine inspections of all dead-end grips in the system. The frequency depends on environmental conditions, conductor load and manufacturer recommendations.
- Visually examine each grip for signs of wear, damage or corrosion and look for loose fasteners or cracks.
- Check the tightness of fasteners, bolts and nuts and use a torque wrench to ensure the hardware is properly tightened.
- Clean the grips of dirt, dust or contaminants using a suitable cleaning method. Use a clean, dry cloth and do not introduce additional contaminants during cleaning.
- Apply lubrication to moving parts to ensure smooth operation.
- Replace any grips with signs of wore, damage or corrosion with genuine replacement parts.
- Check the tension to ensure it is within the recommended range.
- Ensure the grips remain compliant with relevant industry standards and regulations for safety of the installation.
- Consider the environmental conditions to ensure the grips remain resistant to corrosion, UV degradation and other environmental factors.
- Maintain detailed records of your inspections including dates, locations and any findings or maintenance taken.
