Submersible pump cable

Select different specifications of submersible pump cables based on the power of the water pump. JHS submersible cable, the model depends on the pump model.

Rubber sheathed cable is a flexible and movable type of cable made of multiple strands of thin copper wire as conductors, wrapped with rubber insulation and rubber sheath Generally speaking, it includes various types such as universal rubber sheathed flexible cables, welding machine cables, submersible motor cables, radio device cables, and photography light source cables.

Rubber sheathed cables and cables for submersible pumps are mainly used for matching submersible motors The model is JHS, JH.

Submersible pump cable joint sealing device, involving the sealing device of the pump. The junction box is equipped with cable joints, and the cable joints are equipped with compression nuts. There is an expansion sealing gasket between the cable joints and the compression nuts. Due to the expansion sealing gasket between the cable joints and the compression nuts, the compression nuts do not directly contact the cable joints. During assembly, the compression nuts cannot scratch or wear the cable joints, and the sealing effect is good. It is suitable for various submersible pump cable joints.

The specification of the power cable for the submersible pump is determined by two factors: cable heating and voltage drop. In addition to controlling the current density to limit the temperature rise of the cable, the longer the cable length, the greater the voltage drop of the cable, and the greater the impact on the starting performance, operating performance, and usability of the motor. Therefore, for the same submersible pump motor used in the well, when the head of the submersible pump is different and the length of the cable is different, the required cable cross-section is also different.

According to the standard of "Submersible Pump for Wells", the allowable length of different power submersible pump motors with cables of different specifications when the power supply voltage is 380V. When the power supply voltage of the grid is high and stable, or the capacity of the power supply transformer is relatively large and the voltage is high and stable, the allowable length of the cable with the same specifications for the submersible pump motor used in the well can be appropriately extended according to its specific situation (or the cable cross-section of the cable can be appropriately reduced to reduce the cable configuration cost). At this time, the cable with the submersible pump motor has a specified allowable length.
