Product descriptions from the supplier
The 260 umbrella shaped bushing seat is a specialized insulation support accessory for 12kV/24kV SF6 free solid insulated ring main unit. Its core is used for fixing and insulation protection of bushing components, and is compatible with the installation requirements of the 260 specification.
Core Features
Made of solid insulation material, free from SF6 gas pollution, in line with green distribution and environmental protection requirements, with stable insulation performance.
Umbrella shaped structure design enhances creepage distance and anti pollution flashover capability, suitable for complex environments such as outdoor and industrial plants.
The size accurately matches the 260 specification sleeve, with a compact structure and high mechanical strength, firmly fixed without looseness.
Resistant to aging and corrosion, with excellent sealing protection, easy installation, and long-term stability of casing operation.
Applicable scenarios
Suitable for 12kV/24kV SF6 free solid insulated ring main unit, used to support fixed incoming and outgoing line sleeves, PT sleeves and other components, widely used in medium voltage distribution systems such as urban distribution networks, industrial distribution, and new energy power stations.
Product dimensions
It has three key advantages: ① Anti-pollution performance: The umbrella-shaped structure effectively extends creepage distance, reducing the risk of pollution flashover in dusty, humid environments; ② Stable support: High-strength epoxy resin material ensures strong load-bearing capacity, preventing bushing loosening or tilting during long-term operation; ③ Environmental protection: SF6-free design, in line with global carbon neutrality requirements, no gas leakage risk, maintenance-free; ④ Precise matching: Standard 260 size, perfectly compatible with 260 series bushings, easy to install and replace.
It is a specialized mounting and insulation accessory for high-voltage bushings in 10kV/12kV ring main units (RMU) and inflatable cabinets. Core functions: ① Fix and support bushings stably to prevent displacement during operation; ② Cooperate with the umbrella structure to extend creepage distance and improve anti-pollution performance; ③ Enhance insulation isolation between bushings and cabinet bodies. Its working principle relies on high-strength epoxy resin material for mechanical support and insulation, and the umbrella-shaped structure blocks the formation of conductive paths on the surface, ensuring safe operation in harsh environments.

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 -
