234 bushing is a specialized core insulation accessory for 12kV/24kV SF6 free solid insulated ring main unit, adapted to the installation size of 234 specification. The core undertakes the function of line insulation protection and power transmission connection, and is a key connecting component of medium voltage distribution system.
Core Features
Using pure solid insulation material, without SF6 gas and oil medium, without leakage or explosion risk, in line with green distribution and environmental protection requirements, the insulation performance meets IEC standards.
The size accurately matches the 234 specification installation interface, with a compact structure and high mechanical strength. It is resistant to impact and aging, and can adapt to long-term stable operation needs.
Excellent sealing and protection design, moisture-proof, dustproof, corrosion-resistant, suitable for complex working environments such as distribution rooms, industrial plants, underground substations, etc.
Easy to install without additional maintenance, with wiring interfaces that comply with medium voltage distribution standards, ensuring secure line connections and reducing the risk of poor contact.
Applicable scenarios
Suitable for 12kV/24kV SF6 free solid insulated ring main unit, used for cabinet incoming and outgoing lines, PT circuits, busbar connections and other scenarios, widely used in medium voltage distribution systems such as urban distribution networks, industrial distribution, and new energy power stations.
Product dimensions
As a key insulation accessory for solid insulated ring main units (RMU), its core functions are: ① Electrical insulation: Isolate high-voltage conductors from the RMU cabinet to prevent leakage current and ensure operation safety; ② Conductor connection: Realize reliable electrical connection between internal and external conductors of the solid insulated RMU, ensuring stable current transmission. Working principle: It adopts high-performance solid insulation material (epoxy resin) as the main insulation medium, with metal conductors embedded inside; the insulation layer effectively blocks high-voltage breakdown
Key requirements (professional electricians required): ① Pre-installation preparation: Clean the bushing’s insulation surface and RMU’s installation hole to remove dust, oil stains and oxide layer, avoiding insulation reduction; ② Installation operation: Install the bushing vertically/horizontally as required, ensure tight fit with the installation hole, and fasten the fixing bolts evenly (torque meets specifications) to prevent tilting; ③ Conductor connection: Connect the conductor to the bushing’s terminal firmly, ensure good contact to avoid overheating due to poor contact;
