24KV Embedded Poles

Sunway Hanguang's 24KV Embedded Poles leverage the technological expertise accumulated since Sunway Hanguang's founding in 1968, integrating independently optimized primary sealing processes and full-process quality control into production. As a professional manufacturer, it uses APG technology to encapsulate core components such as vacuum interrupters, forming a fully enclosed, fully insulated, and fully shielded modular structure with mature technology and stable performance.

The 24KV Embedded Poles are compatible with 24kV AC systems and various mainstream switchgear types, serving a wide range of fields including power and new energy, and are exported to many parts of the world, demonstrating Sunway Hanguang's global competitiveness as a high-quality supplier.

Core Product Features

1. Excellent Craftsmanship and Superior Insulation

The 24KV Embedded Poles utilize vacuum casting + APG technology, with epoxy resin and special fillers for molding, resulting in no bubbles or cracks and high density. The built-in equalizing shielding ring optimizes the electric field, with partial discharge ≤5pC, and can pass rigorous tests such as pollution and salt spray, meeting the Class IV pollution level, completely avoiding creepage and flashover risks.

2. Robust Structure and Long Lifespan

The epoxy composite structure has a bending strength of ≥20kN and a tensile strength of ≥15kN, resistant to short-circuit impact and vibration, and complies with IEC vibration standards. It features a built-in high-purity Cu-Cr contact vacuum interrupter with a vacuum degree of ≤1.33×10⁻³Pa, a mechanical life of over 1 million cycles, and a record of over 15 years of trouble-free operation.

3. Maintenance-Free, Reduced Operation and Maintenance Costs

The fully enclosed structure isolates external interference, ensuring 30 years of maintenance-free operation under normal use, reducing operation and maintenance costs by over 85%. The modular design supports convenient installation and replacement, facilitating rapid on-site maintenance and improving system availability.

4. Environmentally Friendly and Compliant, Smart Expandability

No oil or SF6 emissions, complying with environmental standards and carbon neutrality goals. Multiple sensor interfaces are reserved, supporting mainstream communication protocols, allowing seamless integration into operation and maintenance platforms to meet intelligent power distribution monitoring needs.

5. Full Process Quality Control, Traceable Quality

Based on our own factory's advanced equipment, each product undergoes 18 comprehensive factory inspections, generating a unique, traceable electronic file. A 10-year limited warranty is provided, guaranteeing insulation performance degradation ≤10% and stable vacuum degree.

6. Wide Compatibility, Strong Adaptability

Can directly replace original poles from brands such as ABB, Siemens, and Schneider, supporting OEM/ODM customization, and is compatible with various medium-voltage switchgear, meeting both new installation and retrofit needs.
