摘要： A trace wire is placed alongside an underground utility for long distance transmission of locating tones. The trace wire has a conductive core. There is an electrically insulating sheath on the core. The sheath has an inner layer in the form of a solid foam of dielectric material. An outer layer of the sheath is a solid dielectric material surrounding the inner layer. This combination of a core conductor with insulating materials in a multi-layered design provides significantly improved properties over current commercially available insulated conductors when used as trace wires. In the presently preferred embodiment of the invention, the trace wire construction includes a 1.6 mm (14 AWG) hard drawn copper conductor to provide low resistance along with high break strength. The inner layer of the sheath is gas injected foamed polyethylene (PE) insulation applied to an overall diameter of 7 mm. The outer layer is solid, medium or high density PE applied over the first layer to an over all outer diameter of 8.5 mm. This dual-layer insulation exhibits an effective relative dielectric constant of about 1.6. The attenuation constant at 500 Hz is 0.227 dB per km maximum. The break strength is about 135 kg and the trace wire is light weight at about 60 kg per km.

摘要： The present invention provides improved compositions of expanded polytetrafluoroethylene (PTFE) and similar polymers and methods for forming and using such compositions. In its preferred embodiment, the present invention employs a mixture of PTFE and expandable thermoplastic microspheres. Through application of an energy source to the mixture, a coherent three dimensional expansion of PTFE can be achieved. The expanded mixture has many of the same beneficial properties of mechanically expanded PTFE and numerous properties previously unavailable with expanded PTFE products.
