Ⅰ. Introduction to 285 Epoxy Resin Cast Bushing
285 epoxy resin bushing is mainly used in the inflatable ring network cabinet,can effectively seal the insulation medium in the cabinet, support theconnection between the fixed switch cabinet and the cable, and increasethe size space of Cr, its rated current can be 630A-1250A, voltagelevel can be used for 12kV and 24kV; the casing of 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
Ⅱ. Features of 285 Epoxy Resin Cast Bushing
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
Ⅲ. Unique Design
1. Uniform Molding
Epoxy resin monolithic molding ensures the integrity and sealing of the product.
2. Highly Conductive Material
Conductive rods use T2 copper-silver plating material make sure high conductivity, low power loss.
3. Fully Shielded Design
It is fully shielded when matched with a detachable cable connector that also gives a comprehensive sealing system safety level.
4. Quick Assembly
It can be assembled fast hence simple to install thus reducing workloads on site therefore improving work efficiencies.
