Medium Voltage Power Cable 8.7/15kV – 33kV | Copper XLPE Insulated PVC Sheathed for Power Grid Distribution

This Medium Voltage (MV) Power Cable is engineered for the efficient and reliable transmission and distribution of electrical power in circuits rated between $8.7\text{kV}$ and $35\text{kV}$ (typically $15\text{kV}$, $20\text{kV}$, and $33\text{kV}$). It is specifically designed for integration into utility power grids, industrial facilities, and large commercial projects.

The cable structure is optimized for high-performance MV applications:

• Conductor: Utilizes high-conductivity Copper (Cu) strands, offering low resistance and high ampacity.

• Insulation: Features Cross-Linked Polyethylene (XLPE), known for its outstanding dielectric strength, high thermal stability, and low dielectric loss factor.

• Screening: Typically includes both a conductor screen and an insulation screen (usually semi-conducting material) to manage electric field stress and prevent partial discharge.

• Outer Sheath: Protected by a tough Polyvinyl Chloride (PVC) Sheath, providing excellent resistance against moisture, chemicals, weathering, and mechanical abrasion.

• Armouring (Optional): Steel Wire Armour (SWA) or Steel Tape Armour (STA) is optionally available for enhanced mechanical protection in direct burial or harsh industrial environments.

(2) Key Features & Advantages

• Superior Thermal Performance: XLPE insulation allows for a higher continuous operating temperature (up to $90^{\circ}\text{C}$) compared to traditional insulation, enabling higher current carrying capacity (ampacity).

• Exceptional Dielectric Strength: XLPE provides high electrical resistivity and low permittivity, ensuring minimal energy loss and maintaining integrity under high electric stress.

• Robust Environmental Protection: The PVC outer sheath is formulated to resist UV radiation, oils, common chemicals, and environmental moisture, extending the cable’s service life.

• High Short-Circuit Rating: Designed to withstand high short-circuit temperatures (up to $250^{\circ}\text{C}$), enhancing safety and system protection.

• High Reliability: The shielded construction effectively mitigates electric field leakage, preventing internal degradation and ensuring long-term operational stability.
