The introduction of the cast steel cross coupling protector to the oil and gas industry in the mid 1980s served to revolutionise the protection of downhole cables used to power electric submersible pumps (ESPs), safety valves and other downhole equipment. Historically, damage to downhole cables due to crushing between the production tubing couplings and the casing internal diameter cost the industry millions of pounds in unscheduled workovers and recompletions. The North Sea is one of the most hostile of environments, but today, cable damage is virtually unheard of. This is directly attributable to the introduction of cast steel cross coupling protectors.
During the past ten years, the cast steel cross coupling cable protector has been introduced throughout the world's oil and gas producing regions and from its humble beginnings in the North Sea is now protecting downhole cables from mechanical damage in thousands of oil and gas wells on land and sea throughout the world.
A full range of all metal cross coupling cable protectors with robust cast steel bodies is offered to the oil and gas industry. This range of cable protectors has been designed with total protection in mind and incorporates new design features which place it ahead of the competition with regard to cable protection.
✔
All metal cross coupling construction to NACE specification MR01-75/95 for sour gas service.
✔
Improved cable guard 'stand off' to minimise potential for damage due to crushing.
✔
Improved contouring of leading edges to 'deflect' away from potential hang up situations.
✔
Alignment of capscrew head with protective rib to substantially increase wear protection.
✔
Interlocking action between clamping arm and casting body to eliminate shear stresses.
✔
Low profile clamping arm shielded from hang up by coupling offset and casting body.
✔
One piece assembly with no loose fittings to fall downhole.
✔
Pre-engaged fasteners for fast and reliable installation to reduce rig time required.
✔
Totally retrievable and re-usable with the minimum of refurbishment.

Q: What is the primary use of a cross coupling cable protector?
It is used to protect downhole cables from mechanical damage caused by crushing between production tubing couplings and the casing internal diameter, specifically for ESPs and safety valves.
Q: What materials are these protectors made of?
They feature an all-metal cross coupling construction with robust cast steel bodies, manufactured to NACE specification MR01-75/95, suitable for sour gas service.
Q: Are these cable protectors reusable?
Yes, they are totally retrievable and re-usable with minimum refurbishment, which helps in reducing long-term operational costs.
Q: How do they help in reducing rig time?
The protectors come with pre-engaged fasteners, allowing for fast and reliable installation, which significantly minimizes the rig time required during deployment.
Q: What design features prevent hang-up issues?
They include improved contouring of leading edges to deflect away from potential hang-up points and a low-profile clamping arm shielded by the casting body.
Q: Are they suitable for harsh offshore environments?
Absolutely. Originally developed for the North Sea, these protectors are engineered for the most hostile environments and are used globally in both onshore and offshore wells.
