Multi-layer insulated conductor having improved scrape abrasion resistance

An insulated conductor comprising:

• an elongate conductor;
• and
• a two-layer insulation system having
• an extruded first insulating layer comprising PEEK overlying the elongate conductor and having an average wall thickness of about 0.003 inches;
• and
• an extruded second insulating layer comprising PTFE overlying and in contact with the first insulating layer and having an average wall thickness of about 0.003 inches.

An insulated conductor comprising:

• an elongate conductor comprising a braided cable;
• and
• a two-layer insulation system having
• an extruded first insulating layer comprising annealed PEEK overlying the elongate conductor and having an average wall thickness of about 0.0055 inches;
• and
• an extruded second insulating layer comprising FEP overlying and in contact with the first insulating layer and having an average wall thickness of about 0.0085 inches.
