Conductor material and size
The choice of the conductor material, copper or aluminum, is a matter of both customer preference and required current carrying capacity. At 230 kV, copper is the 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.
The insulation thickness for 230kV cables is designed to the Southwire standard with a corresponding conductor stress level not to exceed 10kV/mm and a minimum
thickness of 850 mils regardless of cable geometry, within the limits in AEIC specification CS9.
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.
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.
