GAP
Gap-Type
GAP conductors combine thermal-resistant aluminum alloy strands with a high-strength steel core, separated by a gap filled with temperature resistant grease. This design enables high ampacity, reduced sag, and superior durability—making them ideal for reconductoring, long spans, and modern high-voltage networks.
