Product Description
Medium Voltage (MV) Power Cables are electric power cables designed to operate at voltages ranging from 1 kV (1000 volts) up to 35 kV. They are commonly used in various electrical distribution systems, such as substations, industrial applications, and utility grids. MV cables facilitate the transmission and distribution of electrical energy efficiently and safely.
Construction of Medium Voltage Power Cables
Conductors:
Material: Typically made of copper or aluminum, with copper offering better conductivity while aluminum is lighter and more cost-effective.
Configuration: Conductors can be single-core (one conductor) or multi-core (multiple conductors bundled together).
Insulation:
The insulation material surrounds the conductor to prevent electrical leakage and protect against environmental factors.
Common insulation materials include:
Cross-Linked Polyethylene (XLPE): Provides high thermal resistance and excellent dielectric properties.
Polyvinyl Chloride (PVC): Offers good mechanical properties but is less heat resistant than XLPE.
EPR (Ethylene Propylene Rubber): Used for its flexibility and resistance to heat and environmental conditions.
Inner Sheath:
This layer provides additional protection to the insulation, often made from PVC or similar materials to guard against moisture and mechanical damage.
Armor:
In some cables, an additional layer of armor (steel wires or aluminum) is used to protect against mechanical damage and rodent attacks. This is especially common in direct burial applications.
Outer Sheath:
The outer layer protects the cable from environmental exposure, such as moisture and chemicals. It is typically made from PVC or other durable materials.
Types of Medium Voltage Power Cables
Single-Core Cables:
Used primarily in three-phase systems. They can be installed in different configurations (either in trefoil or flat formations).
Multi-Core Cables:
Contain multiple conductors (three or four) assembled together. They are commonly used in applications where space is limited.
Armored Cables:
These cables have an additional layer of mechanical protection, making them suitable for underground or outdoor installations.
Non-Armored Cables:
Typically used for above-ground or indoor applications where the risk of mechanical damage is lower.
Submarine Cables:
Designed for underwater applications, these cables have enhanced insulation and protection to endure the critical environmental conditions found underwater.
Sizes of Medium Voltage Power Cables
The sizes of MV cables are typically specified in terms of the conductor cross-sectional area, measured in square millimeters (mm²). Common sizes include:
10 mm² / 16 mm² / 25 mm² / 35 mm² / 50 mm² / 70 mm² / 95 mm²
120 mm² / 150 mm² / 185 mm² / 240 mm² / 300 mm² / 400 mm²
500 mm² and larger
The appropriate size of cable to use depends on factors such as the current-carrying capacity required, the length of the cable run (which affects voltage drop), and installation conditions (ambient temperature, installation type, etc.).
