Core Engineering Advantages
Triple-Extrusion XLPE Technology
Conductor shield, insulation, and insulation shield are extruded simultaneously in a clean-room environment to ensure zero air gaps and a seamless interface.
≤ 10pC Low Partial Discharge
Our rigorous super-clean material selection and testing guarantee a low partial discharge rate, significantly reducing electrical treeing and extending service life.
99.99% High-Purity Copper
High-conductivity annealed copper minimizes resistance and heat generation, ensuring maximum efficiency for 35KV power distribution.
Structural Anatomy (26/35KV Design)
- Copper Conductor: Compacted stranded copper for high conductivity and reduced cable diameter.
- Conductor Screen: Semi-conductive material extruded over the conductor to uniform the electric field.
- XLPE Insulation: Primary dielectric layer providing high electrical strength and thermal stability.
- Insulation Screen: Semi-conductive layer to smooth electrical stress at the insulation surface.
- Metallic Screen: Concentric copper tape or wire screen for grounding and fault current return.
- Wrapping Layer: Non-hygroscopic binder tape to protect core integrity.
- Outer Sheath: Robust PVC (ST2) jacket providing mechanical protection and moisture resistance.
