This invention provides a tubing hanger system which isolates production tubing from a power cable, protects the cable from high pressure, and enables pressure testing of the production and cable seals. A tubing hanger member is seated in a tubing head to seal against a central bore, and a tubing head adapter is fastened above the tubing head. The tubing head adapter and the tubing hanger member form a tubing port and a cable port. A tubing seal-off nipple connects and seals the tubing port in each of the tubing head adapter and the tubing hanger member, and a cable seal-off nipple connects and seals the cable port in each of the tubing head adapter and the tubing hanger member. Seals are provided between the cable and cable port in the tubing hanger member, and between the cable and cable port in the tubing head adapter.
