FAQ From Customers
-
What is the difference between wires and cables?
A wire is a single conductor that carries electricity, while a cable is a group of two or more insulated electrical wires bundled together. Wires and cables are used to transmit electrical power or signals, but cables provide better protection and are often used where safety and durability are critical. -
How do I choose the right electrical cable for my project?
When selecting an electrical cable, consider the required voltage, current capacity, installation environment, and safety standards. For example, choose power cables for high-load transmission, solar cables for photovoltaic systems, or insulated electrical wires for indoor wiring. Always ensure the cable meets international standards such as IEC, UL, or ISO. -
What are the common types of wires and cables?
Common types include bare conductor cables for overhead transmission, power cables for industrial and residential electricity supply, solar cables for renewable energy systems, insulated cables for building wiring, grounding wires for safety, and submarine cables for undersea power transmission. -
Why is testing important for electrical wires and cables?
Testing ensures wires and cables meet safety, durability, and performance standards. High-quality electrical cables undergo conductivity, insulation, fire resistance, and mechanical strength tests to guarantee reliable operation. Properly tested electrical wires reduce energy loss, prevent short circuits, and increase system safety. -
