ABSTRACT:
An extrusion head may be provided. The extrusion head may include an inner flow path, an outer flow path, and at least one sealant flow path. The inner flow path may be configured to direct a flow of an inner layer around a conductor. The outer flow path may be configured to direct a flow of an outer layer around the inner layer. The at least one sealant flow path may extend to a connecting point with the inner flow path and the outer flow path. The at least one sealant flow path may be configured to direct a sealant to fill at least one sealant channel region between the inner layer and the outer layer. The connection point may be configured to cause the flow of the inner layer and the flow of the outer layer to join before the sealant fills the at least one sealant channel region.
