This cable protector is made of 4140 alloy steel, a high‑strength, wear‑resistant American‑standard alloy widely used in oilfield equipment. It is specially designed for protecting downhole oilfield cables, effectively shielding cables from extrusion, friction and impact during well operation. With excellent mechanical properties, high toughness and corrosion resistance, the product adapts to harsh underground working environments. Manufactured by precision casting process, it features stable structure, precise size and long service life. It can reliably prevent cable damage caused by complex downhole conditions, ensure safe and stable operation of oil production systems, and is widely applied in various oilfield exploitation projects.
