As we all know, the insulating rubber plate is an auxiliary safety tool in the distribution room. It is mainly used by the power engineering staff when the distribution room is working. The insulation layer is paved in front of the distribution box. The voltage resistance and thickness of the insulating rubber plate are different in different distribution rooms. Today I tell you the application standard of the insulating rubber plate in different distribution rooms
Distribution rooms of 8Kv and below: for distribution rooms of 8Kv and below, the specification and model of insulating rubber plate shall be 3mm thick, and its Zui high voltage level shall be 8Kv. Due to the different withstand voltage levels in the bottom voltage distribution room, there is no fixed thickness matching in the national standard. Generally speaking, the default setting is 8Kv and below, and the application of 3mm thick insulating rubber pad is more effective.
8kv-10kv distribution room: in the distribution room, there are more 10kV distribution rooms. Generally, the national standard of 10kV is 5mm thick. In addition, the default setting for the distribution room above 8Kv and below 10kV is 5mm thick insulating rubber plate.
11kv-15kv power distribution room, in the power distribution room, when the voltage is higher than 10kV and lower than 15kV, the insulation rubber plate with national standard specification of 6mm is generally applied, and the withstand voltage is 15kV, which completely meets the application requirements in the power distribution room.
16-25kv distribution room, in the distribution room, if the voltage is higher than 15kV and lower than 25kV, it is generally applied with 8mm thick insulating rubber plate in the national standard specification, and 8mm thick withstand voltage 25kV can meet the application requirements in the upper distribution room.
26-30kv distribution room, in which the voltage is higher than 25kV and lower than 30KV, the insulation rubber plate with 11mm thickness in the national standard specification is generally applied, and the voltage withstand of 11mm thickness is 30KV, which completely meets the voltage withstand requirements of the above distribution room.
31-35kv power distribution room, in which the voltage is higher than 30KV and lower than 35kV, is generally applied with 12mm thick insulating rubber plate in the national standard specification, and the voltage withstand of 12mm thick is 35kV, which meets the requirements of the above power distribution room.
