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.
