High-Performance Embedded Pole Supplier for Switchgear

Embedded Pole is a core component of high-voltage vacuum circuit breakers. Sunway Hanguang, as a professional manufacturer, strictly adheres to the JB/T 11203-2011 standard, relying on its own factory to produce high-quality products.  As a reliable supplier, it provides solutions adapted to multiple scenarios globally. All products are manufactured in China, offering both stability and cost-effectiveness.

Its core structure consists of a vacuum switch tube encased in cushioning material and epoxy resin, replacing traditional support components to achieve integrated modularization. It uses an automatic pressure gel process for integrated encapsulation.  Prices for different models range from several hundred to several thousand RMB. Based on rated voltage and application scenarios, Sunway Hanguang Embedded Poles are mainly divided into three categories, all meeting or exceeding the E2 level requirements of GB1984-2003 and IEC62271-100, as follows:

I. 12kV Embedded Pole

This is Sunway Hanguang's mainstream basic model, suitable for 12kV vacuum circuit breakers, widely used in medium and low-voltage power distribution scenarios such as industrial plants and residential areas.

1. Core Specifications and Structure

High-quality epoxy resin encapsulation, combined with a high-performance vacuum switch tube, automatically pressure-gel molded, with a modular design, compact size, and few removable parts.

2. Performance Characteristics

Reliable insulation, excellent vacuum sealing, resistance to high and low temperatures and mechanical shock, maintenance-free, easy installation, and suitable for long-term stable operation in medium and low-voltage power distribution.

3. Product Advantages

Isolation from the external environment improves external insulation strength, simplifies assembly processes and reduces errors, offers outstanding cost-effectiveness, and reduces future maintenance costs.

II. 24kV Embedded Pole

This is a mid-range model, suitable for 24kV vacuum circuit breakers, used in medium and high-voltage scenarios such as regional substations and large industrial parks that require higher performance.

1. Core Specifications and Structure

Upgraded from the 12kV model, with a thicker encapsulation layer and higher-specification components, improved current carrying and insulation performance, balancing miniaturization and practicality.

2. Performance Characteristics

Continuing the brand's core performance, with superior mechanical, electrical, and heat aging resistance, upgraded insulation and impact resistance, and easy integration into switchgear. 

3. Product Advantages

Compared to the 12kV model, the external insulation and current carrying capacity are significantly improved, the sealing is better, and the assembly and reliability are optimized, reducing operation and maintenance costs.

III. Comparison of Core Parameters of Two Product Categories

Sunway Hanguang's two voltage level products, leveraging the advantages of the Chinese industrial chain, are manufactured with precision in our own factory and can provide customized solutions. The core differences are as follows:

1. 12kV level: Medium and low voltage power distribution, moderate current carrying capacity, high cost-effectiveness, and wide application;

2. 24kV level: Medium and high voltage power distribution, upgraded performance, and adaptable to complex working conditions;

In summary, Sunway Hanguang Embedded Poles, categorized by voltage level, cover all scenarios.  Thanks to high-quality materials and precision manufacturing, we have become a globally trusted manufacturer and supplier. Our products are manufactured in China, providing efficient and stable core component solutions for high-voltage power distribution.
