It is a kind of artificial lifting oil production method that uses submersible motor to drive electric submersible multistage centrifugal pump to lift underground crude oil to the surface. Electric submersible pump or electric submersible pump for short.

The electric submersible pump system includes three parts: underground unit, ground control and power transmission. Cable protector is mainly used in the power transmission part to protect the cables of submersible pump power system.

Downhole units mainly include electric submersible multistage centrifugal pump, submersible motor and submersible motor protector; The ground control mainly includes oil production wellhead device, electric submersible pump control cabinet and electric submersible pump transformer; The power transmission part is the electric submersible pump cable (including cable protector).

The electric submersible pump cable is used to send the ground power to the underground, and the cable of the submersible pump is effectively protected by cable protector to prevent the cable damage caused by sharp objects such as sand and gravel in the pipeline. Finally, the power is transmitted to the submersible motor to drive the electric submersible multi-stage centrifugal pump.

Cable protector can easily cope with various underground passage conditions. According to different situations, cable protector has various shapes to protect cables of different shapes, such as flat, round and square cables, which have corresponding cable protectors.
