Product features
●Enables connections between multiple switchgear
cabinets by connecting to switchgear bushings.
●System voltage: 8.7/15 kV, 12/20 kV
●Continuous rated current: 630 A/1250 A.
Characteristics
● Provides fully insulated and fully sealed separable connections when used with Type C bushings. Single-pole, plug-in design.
● Busbars consist of round copper rods (tubes) coated with composite silicone rubber insulation.
●Shielded busbars have no minimum phase-to-phase distance requirements and are unaffected by pollution or condensation.
