The choice of the conductor material, copper or aluminum, is a matter of both customer preference and required current carrying capacity. For larger loads, copper will be your most common option. When both copper and aluminum conductors can meet you requirements, the more economical solution will be a function of the metal and the cable components costs in effect. Contact Southwire for your custom quote.

Insulation Thickness:
Cables referred to by "Traditional Wall" insulation (800 mils) follow the traditional insulation wall practice referenced in ICEA standard S-108-720 appendix F as still specified by a number of customers and utilities. For cables with a radial moisture barrier, "Southwire(SW) Standard Wall" thicknesses of 550 mils in accordance with AEIC specification CS9 are recommended. For applications requiring smaller cable diameters, cables with reduced insulation thickness are available upon request within the stress limits in AEIC specification CS9.

Sheath Material:
Copper and aluminum corrugated sheaths offer the best mechanical and moisture protection for your HV cable. In addition, copper will provide better short circuit performance and improved connectability. Another option is our composite laminate sheaths in both copper and aluminum that offer excellent protection against moisture
ingress.

Jacket:
Our standard outer jacket is extruded LLDPE with a co-extruded outer semiconductive polyethylene layer for jacket integrity testing. Halogen Free Fire Retardant (HFFR) compounds are available upon request for installations in cable trays and ventilated troughs.
