12KV Embedded Poles

As a veteran high-voltage electrical equipment manufacturer established in 1968, Sunway Hanguang integrates independently optimized processes and full-process quality control into product manufacturing. The 12KV Embedded Poles use epoxy resin as the core material, encapsulated through vacuum casting + APG technology, enhancing insulation and structural stability. Compatible with mainstream switchgear types, originating from China, it boasts excellent quality and is exported globally, serving as a core component for medium-voltage equipment upgrades.

Core Product Features

1. Advanced Technology, Excellent Insulation Performance

The 12KV Embedded Poles utilize vacuum casting + APG composite technology, ensuring the epoxy resin is free of bubbles and cracks, and has high density. Combined with an internal voltage equalization shielding ring to optimize the electric field, the partial discharge is <5pC, passing rigorous tests for pollution and condensation, preventing creepage flashover, and suitable for Class IV pollution environments.

2. Robust Structure, Strong Stability

The epoxy composite material is reinforced with fibers, with bending strength ≥18kN and tensile strength ≥12kN, capable of withstanding short-circuit electrodynamic shocks. It features an embedded high-purity Cu-Cr contact arc extinguishing chamber with a vacuum degree ≤1.33×10⁻³Pa, a mechanical life of over 1 million cycles, and over 15 years of trouble-free operation in the field.

3. Maintenance-Free Design, Efficient Operation and Maintenance

The fully enclosed structure isolates external influences, achieving 30 years of maintenance-free operation, reducing maintenance costs by more than 85%; the modular design supports direct bolt connection/plug-in installation, making replacement convenient and suitable for rapid maintenance needs.

4. Environmentally Friendly and Smart Expandable

No oil, SF6, or toxic gas emissions, complying with environmental standards. Reserved interfaces for temperature sensing and partial discharge detection, supporting multiple communication protocols, and connectable to intelligent operation and maintenance platforms to meet digital monitoring needs.

5. Strict Quality Control, Controllable Quality

Sunway Hanguang has a professional factory equipped with advanced testing equipment. Each product undergoes 18 comprehensive factory inspections, generating a unique traceable electronic file, and comes with a 10-year warranty, ensuring performance degradation ≤10%.
