Cast steel cable protector is made of carbon steel, stainless steel by Investment casting(lost wax casting, precision casting), water glass process, is widely applied to tubing hoop, safety valve protection, sub-sea completions, gauges completions and so on. 
The body of cable protector adopts investment casting technical and special toughness process. It's strength and reliability could be more distinct with all-cast grade material. Being unique design of smooth streamline, it prevents damage during dynamic motion of the production tubing and ensures continuity and accuracy in the gauges complication. Cable protector can be rapidly and reliably installed with no separate or loose parts or pins, prevents cross threading, and reduces the potential hang up risk. Meanwhile, it demounts easily and allows reinstallation.
