EN 50386 10KV 250A High Voltage Porcelain Transformer Bushing

Product Overview

High - voltage porcelain transformer bushings serve as indispensable components in electrical systems, particularly for transformers within power substations. They bridge the internal windings of transformers and external circuits, ensuring safe and efficient high - voltage power transmission while providing crucial insulation.

Specification

Structural Composition

• Insulation and Conduction Elements

• The core structure integrates porcelain insulation (the dark - brown segment) and metal connection components (e.g., golden connecting screws and terminals). The porcelain material offers excellent dielectric strength, resisting electrical breakdown under high - voltage conditions. Metal parts ensure reliable electrical conduction, facilitating the flow of current between the transformer and external systems.

• Some variants incorporate additional black accessories, such as seals and fixing structures. These enhance the bushing's functionality, contributing to both insulation integrity and stable installation.

• Installation - Related Components

• Top terminals come in diverse forms, including screws and flat - plate types. This variety allows for flexible connection to different external circuit configurations.

• At the bottom or side, installation structures are tailored to fit transformer oil tanks. They work in tandem with sealing parts and fixing components, enabling a secure and leak - proof installation.

These bushings are predominantly installed on electrical equipment like transformers. Their primary function is to establish a high - voltage electrical connection between internal windings and external circuits. They are a staple in substation setups and power transformer support systems. By ensuring insulation and meeting conduction requirements, they enable the safe transmission of high - voltage electricity, which is vital for the stable operation of power grids.

• Packaging Design

• To safeguard the bushings during transit and storage, a partitioned packaging approach is adopted. This may involve wooden or paper partitions. Each bushing (or groups of bushings) is independently protected, preventing contact - induced damage. Some units are additionally wrapped in plastic film, adding an extra layer of protection against moisture and minor impacts.

• Operational Benefits

• This packaging method simplifies batch management and delivery processes. It ensures that bushings reach their destination in optimal condition, ready for installation.
