Tensile Strength: Assess the tensile strength of the conductor to ensure it can withstand expected loads.
Support Structures: Evaluate the support structures and spacing requirements to maintain the integrity of the conductor under various conditions.
3.6 Compliance with Standards and Regulations
Adhering to industry standards and regulations is critical when selecting it. Compliance ensures safety, reliability, and performance. Check for:
National Electrical Code (NEC): Verify that the selected conductors meet NEC requirements for installation.
ASTM Standards: Refer to ASTM standards for material properties and testing of it.
3.7 Cost Considerations
While these conductors are generally more cost-effective than copper, it is essential to evaluate the overall costs associated with installation and maintenance. Consider:
Initial Costs: Assess the upfront costs of purchasing Aluminum Conductors.
