Insulation material of the slip ring plays a Critical role, that is isolation between rings of the slip ring and the insulation between slip ring spindle and rings of the conductive slip ring, thus, the selection of the insulation material of the slip ring must be paid attention.
Insulation material of the slip ring generally has the following functions:
1 ) The insulation between the rings of the conductive slip ring.
2 ) The insulation between the rings and the shafts of the conductive slip ring.
3 ) The insulation between the brushes and between the brushes and slip ring housing.
Selection of the insulation material of slip ring, you must pay attention to the following points:
1. The mechanical strength of the insulation material of the slip ring, must meet the pressure, centrifugal force, the locking force generated by the normal operation of the slip ring.
2. The processing performance of the insulation material of the slip ring: slip ring material of the slip ring must be processed in conventional and low-cost manner.
3. The electrical performance of the insulation material of the slip ring: insulation performance is the basic requirement , you must also determine the resistance to high voltage , ensure that the rated voltage without breakdown.
4. The absorbent and the moistureproof performance of the insulation material of the conductive slip ring: the performance ensure the insulation material to work properly in the required environment .
5. The temperature characteristics of the insulation material of the slip ring: need to meet the requirement of the specified operating temperature, stabilize the relative performance.
6. The costs of the insulation material of the slip ring: the insulation material of the conductive slip ring, must be considered to obtain easily and at low cost , to avoid increasing the overall cost of the slip ring.
Currently MOFLON Company have done extensive tests, the insulation material used in the slip ring can reach the following upmost requirements:
1) The maximum withstand voltage is 10000V
2) The maximum temperature endurance is 400 degrees
