FAQ From Customers
-
What is a bare conductor cable?
A bare conductor cable is an electrical cable made of bare aluminum or bare copper conductors without any insulation. These cables are widely used in overhead power lines, power transmission systems, and aerial conductors. Bare conductor cables offer excellent conductivity and high tensile strength, making them ideal for long-distance energy transfer and outdoor installations. -
Bare Copper Conductors vs Bare Copper Ground Conductors, what’s the difference?
Bare copper conductors are typically used in power transmission, providing high conductivity for energy delivery. Bare copper ground conductors, however, are designed for grounding purposes and ensure safety by providing a path to dissipate fault currents safely into the earth. While both are made of copper, ground conductors are often thicker to handle fault conditions without overheating or breaking. -
What is the difference between AAC and ACSR conductors?
AAC (All Aluminum Conductor) and ACSR (Aluminum Conductor Steel Reinforced) differ primarily in their construction. AAC conductors are made entirely of aluminum, offering lightweight and high conductivity. ACSR conductors, on the other hand, have a steel core that enhances tensile strength, making them ideal for long-distance transmission and high mechanical stress. While AAC is suitable for shorter distances, ACSR is typically used for overhead lines with longer spans and high voltage transmission. -
What is the difference between bare conductor and insulated conductor?
Bare conductor cables are uninsulated and typically used in overhead power lines where external insulation is unnecessary. In contrast, insulated conductor cables have a protective layer of material like PVC or XLPE, offering protection against electrical shock and short circuits. Insulated cables are commonly used for underground installations or where conductors are exposed to moisture, chemicals, or mechanical damage. -
What types of electrical cables are used for power transmission?
Various types of electrical cables are used for power transmission, including bare conductor cables like AAC, ACSR, and AAAC. These cables are ideal for overhead power lines because of their high conductivity and durability. For underground or shielded installations, insulated conductors are often used. NPC Electric manufactures electrical cables for both low voltage and high voltage systems, ensuring reliable and efficient power delivery in diverse applications.
