ABSTRACT:
The flat multiconductor cable contains live, neutral and ground conductors lying generally parallel to each other and in side by side, single-plane relation. The live and neutral conductors are sealably surrounded by a relatively hard, polyetherimide material that is substantially free from attack from calcium hydroxide. An outer jacket or casing of polyvinylchloride (PVC) sealably surrounds the polyetherimide layers and contacts the ground conductor. The PVC is substantially free from attack in an alkaline environment. The polyetherimide layers are extruded over the live and neutral conductors providing a seal therearound and thereby a barrier to moisture. The PVC layer is then extruded over the conductors providing a further seal around the polyetherimide layers.
