The utility model relates to a transformer substation is with keeping apart rail, including the rail body, rail body base both sides are provided with participates in for what peg graft with ground, rail body upper portion openly one side is provided with the tie point of living, and it is connected with the vaulting pole to live on the tie point of living the rail body upper portion back is provided with another tie point of living with the aforementioned tie point opposite side of living, lives on this work tie point and is connected with another vaulting pole. Since implement above -mentioned technical scheme, this application simple structure, the insulating material preparation stereoplasm of adoption hides the fence, hides the fence both sides and respectively installs a supporting leg additional, can open when the supporting leg uses, and it increases the effect that hides the fence steadiness to play, and it can pack up to hide fence both sides supporting leg after the messenger uses up. Prevent wind insulating stereoplasm to hide that the fence singlely can make things convenient for, swift transport, installation, it is effectual, be fit for promoting high voltage transformer substation and do the security isolation measure use when equipment high -voltage testing or overhaul of the equipments.
