Regarding the insulation of rubber seals, do you know? Do you know from which aspects the insulation performance of rubber seals can be evaluated? Let’s take a look at the relevant content below.
The insulation performance of the insulating rubber seal board is one of the main symbols to evaluate the insulation quality, which is reflected by the insulation resistance. We measure the insulation resistance of a product, which refers to the insulation resistance between some charged and exposed non-charged metal (case). According to different commodities, apply a DC high voltage, such as 100V, 250V, 500V, 1000V, etc., the rule is a low Insulation resistance value. In some regulations, the insulation resistance is not less than 1MΩ for every kV voltage.
From what aspects to evaluate the insulation of rubber seals
Now in the product specifications of household appliances, usually only the thermal insulation resistance is regulated, and the insulation resistance value under the normal condition is irregular, and the insulation resistance value under the normal condition is determined by the enterprise specification. If the normal insulation resistance value is low, there may be some danger or damage in the insulation structure. For example, the insulation resistance of the motor winding to the shell is low, which may be caused by damage to the insulation of the equalizing groove of the winding when the wire is embedded.
