GORE Magnet Wire is designed specifically to operate reliably in extreme oil and gas downhole environments, minimizing the risk of catastrophic failures for maximum tool-run times. Our mechanically robust wires have a unique engineered fluoropolymer insulation that’s exceptionally resistant to difficult conditions like chemicals, hydrolysis, and up to high pressure, high temperature (HPHT) environments.

We compared our magnet wire to a polyimide enameled wire using ASTM/NEMA MW 1000 test method. For both wires, we used the same AWG size with comparable insulation thicknesses. We tested the dielectric voltage breakdown after 12 days exposure to hydrolysis in 0.3% H2O and synthetic oil at 280°C.

Results showed that our magnet wire maintained maximum voltage endurance after continuous exposure to hydrolysis and harsh fluids at elevated temperatures. But, the polyimide enameled wire became brittle and cracked right away under mechanical stress. This type of wire lost its insulation resistance and voltage breakdown performance, which is unacceptable when trying to avoid tool failures, keep on schedule, and stay on budget.

GORE Magnet Wire is proven to provide durable mechanical protection and superior electrical performance continuously in severe downhole environments — extending motor life and increasing tool reliability for less risk of unexpected catastrophic failures.

GORE Magnet Wire provides manufacturers with many benefits that improve electrical and mechanical performance such as:

• enhanced durability due to specialized insulation materials
• exceptional resistance to aggressive chemicals and hydrolysis
• superior electrical performance in wide-ranging temperatures up to 260°C
• proven highest voltage endurance in harshest downhole environments
• longer motor life and increased tool reliability
• minimize the risk of unexpected catastrophic failures
