In today’s oil and gas industry, downhole tools need to be smaller while maintaining excellent signal integrity. At the same time, these tools are exposed to increasingly challenging environments that can cause frequent cable failure — from sharp edges and burrs in small spaces during installation to high pressures, extreme temperatures and vibration during drilling.

The costs and consequences due to cable failure can be substantial across the entire supply chain — including downtime costs, lost production and expensive tool replacements. It’s all about tool reliability and durability, and this is where the expertise of Gore makes a difference.

GORE Hook-Up Wires for downhole equipment are thinner than alternatives and more robust to stand up to harsh environments. We engineer our wires specifically to withstand extremely harsh conditions without compromising the mechanical and electrical performance of the tools. Their small size and enhanced mechanical performance simplify the complex design challenges that can affect equipment life and reliability in extreme temperatures.

GORE Hook-Up Wires maintain the same signal integrity and power performance in less space and reduce rework, re-testing and downtime due to tool failure — resulting in longer tool life that reduces your total cost of ownership.

Increased Design Freedom with Smaller Wires

GORE Hook-Up Wires require less space — more than 30% less — than a NEMA HP3 Type E AWG 24 wire. The wires’ smaller diameter and improved dielectrics enable you to increase the number of conductors in a given space or reduce the amount of space required for the wires — all of which translates to more design freedom.



Added Durability for Easy Installation and Longer Tool Life

GORE Hook-Up Wires are more durable with thinner insulation than typical hook-up wires, providing greater cut-through resistance at higher temperatures. Our wires’ durable construction increases first-pass yields and reduces the risk of tool failures due to insulation damage. They’re more flexible with a tighter bend radius for easier routing in smaller spaces. In comparison, the NEMA HP3 wires will short circuit at lower temperatures.


GORE Hook-Up Wires are equally beneficial for manufacturers and end users. Manufacturers can take advantage of the wire’s small size and durable material to manipulate them to fit their designs, while end users in downhole environments will see the benefits of the wire’s long service life, flexibility and superior performance the first time and every time.

Benefits of GORE Hook-Up Wires include:

  • Increased design options with smaller diameters and more durable construction
  • Superior electrical and mechanical performance in extreme environments with temperatures up to 260°C
  • Longer tool life with abrasion-resistant and low-creep wire insulation
  • Reliable installation due to cut-through resistance that eliminates damage from sharp edges or burrs
  • Easy routing with smaller, more flexible wire
