Gas-insulated RMU, 290 Epoxy Bushing

Ⅰ. Introduction to 290kV Epoxy Bushing

290 epoxy 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

Ⅱ. Features of 290kV Epoxy Bushing

1. Excellent Insulation and Sealing Performance

This bushing head perfectly matches SF6 gas-insulated cabinets by sealing the insulation medium inside the cabinet so that there is no possibility for gas leakage, and a stable insulation environment can be maintained. When all detachable cable connectors are used, it gives full shielding and sealing that bars moisture as well as dust and other impurities from entering; thus, safe operation of the electrical system is guaranteed, together with its service life prolonged.

2. Great Conductivity and Strong Durability

The conductive rod comprises T2 copper with a silver-plating treatment. This material conducts very high conductivity, which reduces resistance and hence power losses as well as improves efficiency in power transmission. In addition, since T2 copper has high-strength and tough material, together with rugged protection of epoxy resin casing, it ensures sure cable head keeps stable performance under different harsh environments against high mechanical stresses, keeping the connection reliable.

3. Fast Build and Simple Setup

Made with thought for the user, this item has a fast and simple build design. Its joined epoxy resin casting method makes sure all parts fit well, cutting down on work and trouble during on-site build. Users can quickly set up the cable head without hard tools or boring steps, greatly saving time and labor costs while making work better

This epoxy bushing delivers excellent performance on indicators after rigorous electrical performance testing. It has a power frequency withstand voltage of 68kV/1min, less than 5pC partial discharge at 26.4kV, and can withstand impulse voltages of 125kV ±10 times. Great electrical performance parameters allow it to fit complicated electrical environments of high voltage and high current and be the solid foundation for stable operation in power systems.

4. Authoritative Certification

This product is certified and tested by CEPRI, the China Electric Power Research Institute, under IEC 60502-4:2010 and GB/T 12706.4-2008 international and national standards which it has implemented. This authoritative certification not only demonstrates that the product quality and performance level have attained an industry-leading standard but precipitates reliable quality assurance to the users ensuring peace of mind during use.
