China A27 Cable Protector Factory - Durable Cast Steel Cable Protector Clamps from Leading Suppliers
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.
Wei Fang Jun Long Ltd offers a full range of all metal cross coupling cable protectors with robust cast steel bodies to the oil and gas industry. This new 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.

❓ Frequently Asked Questions
Q
What is a cross coupling cable protector used for?
A cross coupling cable protector is used to protect downhole cables from mechanical damage caused by crushing between production tubing couplings and the casing internal diameter. It is essential for safeguarding cables powering electric submersible pumps (ESPs), safety valves, and other downhole equipment.
Q
What material is used in the construction of these cable protectors?
The cable protectors feature an all-metal cross coupling construction with robust cast steel bodies, manufactured to NACE specification MR01-75/95, making them suitable for sour gas service environments.
Q
Are the cross coupling cable protectors retrievable and reusable?
Yes. The cable protectors are totally retrievable and re-usable with the minimum of refurbishment required, providing excellent long-term value and reducing overall operational costs.
Q
How do these protectors reduce installation time on the rig?
The protectors come with pre-engaged fasteners throughout the range, enabling fast and reliable installation. This design significantly reduces the rig time required during deployment, lowering operational costs.
Q
Where are cast steel cross coupling cable protectors commonly used?
Originally developed for the North Sea — one of the world's most hostile environments — these protectors are now used in thousands of oil and gas wells both onshore and offshore across the globe, covering all major oil and gas producing regions.
Q
What design features help prevent hang-up during installation or retrieval?
The protectors feature improved contouring of leading edges to deflect away from potential hang-up situations, a low profile clamping arm shielded by the coupling offset and casting body, and an interlocking action between the clamping arm and casting body to eliminate potential shear stresses on the capscrews.
