For submersible motors, the use of PVC insulated single core winding wire is a common choice. Below is the relevant information:

1. Insulation material: PVC (polyvinyl chloride) is a common insulating material with good electrical insulation properties and chemical resistance. It is an inexpensive and easily processed material for general low voltage applications.


2. Single-core winding wire: Submersible motors typically use a single-core winding wire, i.e., a winding consisting of a single conductor. This design is simple and suitable for lower power applications. Single core winding wire uses one conductor and insulates the conductor by insulating material.

3. Advantages:

   - Low cost: PVC insulation is relatively inexpensive, making submersible motors with PVC-insulated single-core winding wires low cost.
   - Good electrical insulation properties: PVC has good electrical insulation properties, which can effectively isolate the winding wire from other parts of the electrical connection to ensure safe and reliable operation.
   - Chemical resistance: PVC has good resistance to general chemicals and can adapt to the water environment that submersible motors may encounter.

4. Limitations:

   - TEMPERATURE LIMITATIONS: PVC's relatively low heat resistance limits its temperature range of use. In high temperature environments, PVC insulation may soften, deform or decompose, resulting in a loss of insulation performance.
   - Power Limitations: PVC insulated single core winding wire is suitable for lower power applications. For higher power submersible motors, other insulation materials or multi-core winding designs may be required.

The choice of PVC insulated single core winding wire needs to be evaluated based on the specific application requirements and specifications of the submersible motor. In some special environments or requirements, other types of insulation materials or designs may be required. Be sure to select the appropriate winding wire material and construction for your submersible motor according to the relevant standards and guidelines.
