Product descriptions from the supplier
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
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;
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

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
