Product introduction:
290 bushing is mainly used in the inflatable ring network cabinet,it can effectively seal the cabinet insulation medium, with strongsupport fixed effect, make the switch cabinet and cable moreeffectively connected, its rated current can be 630A-1250A, voltagelevel can be used for 12kV and 24kV; casing choose high quality epoxyresin and copper conductive rod, using no local induction network, canshield grounding or connect live display.
Product execution standards: IEC60502.4, GB/T12706.4,GB/T11022
Product features:
Incoming (outgoing) cables for SF6 gas-insulated cabinets
Integrated molded with epoxy resin
The conductive rod is made of T2 copper silver-plated material with high conductivity.
It can be used in conjunction with compatible separable cable connectors to provide full shielding and sealing.
Quick assembly and simple installation
