The reasons for the low motor insulation resistance failure are: (1) The inside of the motor is flooded and damp; (2) There are debris and dust on the windings; (3) The internal winding of the motor is aged. Treatment method: the first case is the internal drying treatment of the motor; the second case deals with the internal debris of the motor; the third case needs to check and restore the insulation of the lead wire or replace the insulated wire plate of the junction box; the fourth case checks the winding aging in time. In case of timely replacement of the windings.
The function of heat shrinkable tube is the insulation, sealing and protection of cable. To put it simply, the heat shrinkable tube has the function of sealing, waterproof and electrical insulation on live equipment.
There are many kinds of appearance of heat shrinkable tubes. Different colors are used in different places and can also play a distinct role in marking different electrical edges.
Heat shrinkable tubes are generally used in wiring harnesses, cables, high and low voltage electrical cabinets, substation power projects and other places that need insulation protection.
nsulation tubes also exist in common household appliances at home, such as the heating base plate of electric kettle and the wiring harness of heater of PTC of air conditioner, etc. Heat shrinkable tubes can generally be seen in these places.
