TEC Cable Custom Cable Solutions

Structure Description

The cable is designed with a multi-layer structure to ensure reliable performance in harsh downhole environments. The structure consists of:

1. Steel Wire Armor
   • High-strength steel wire armor provides excellent mechanical protection, tensile strength, and resistance against impact, crushing, and external pressure during installation and operation.
2. Conductor
   • Conductors are available in high-purity bare copper wire or optical fiber options.
   • Copper conductors provide stable electrical transmission, while optical fibers support high-speed data communication and real-time downhole monitoring.
3. Insulation Layer
   • High-temperature and chemical-resistant insulation materials are applied to ensure electrical stability, insulation performance, and long-term operation under high-pressure and high-temperature conditions.
4. Sealing Layer
   • A specialized sealing structure prevents fluid penetration and protects internal components from moisture, corrosion, and downhole chemicals.
5. Outer Jacket / Sheath
   • The outer sheath is made of durable corrosion-resistant materials, providing protection against abrasion, pressure, temperature variations, and harsh well environments.
