In order to ensure the proper performance of some specific applications, such as submersible pumps, it is imperative that the cable is chemically resistant to the pump oil. In this way, the flexible pipes have as their main function, to adequately isolate and cover electrically the welds of the connections between the connecting cable, the coil wires and other wires.
To ensure that they can mold to the weld points and lashing of the coil head, the tubes need to be flexible. In electric motors mrosupply flexo, three types of tubes are used, the heat shrinkable polyester tube, the polyester weave tube coated with acrylic resin, and the glass fiber tube coated with silicone rubber.
The connecting cables must be properly designed from specific materials, elastomeric insulation. It is necessary to emphasize that they always need to be of the same thermal class as the motor. These materials have a great electrical resistance, which together with the adequate flexibility, allows simple handling to occur in the course of processes of extreme importance, such as manufacturing, maintenance and installation of the motor, for example.
