Because of its good electrical performance, stability, solvent resistance, corrosion resistance of impregnating paint, the surface of heat shrinkable tube can also be marked with identification letters according to the requirements of motor design, so heat shrinkable tube can be used to replace the traditional metal aluminium sheet which is easy to fall off and break when designing the lead wire of motor stator and its winding accessories. System.
The shrinkage rate of heat shrinkable pipes, the uniform identification of all series of motors, and the more striking and beautiful identification factors should be taken into account when using heat shrinkable pipes as lead marks in the design of lead wires. The radial dimensions of heat shrinkable pipes, the printed letters and their colours, and the colours of heat shrinkable pipes should be specified in detail.
When using heat shrinkable tube to design the lead sign of winding accessories, besides specifying the radial size and respective color of the heat shrinkable tube of the winding accessories lead of the sleeve, it is also required to mark the heat shrinkable tube of the thermistor lead with the letter TP, the heat shrinkable tube of the heater lead with the letter HE, and the thermocouple lead with the letter HE. TC letters are marked on the heat-shrinkable pipe and TB letters are marked on the heat-shrinkable pipe of the thermostat lead wire to facilitate identification.
