Keltajohtimilla

Keltajohtimilla, also known as yellow wires, are a type of electrical wiring used in various applications, particularly in low-voltage systems such as telecommunications, audio, and control circuits. They are typically made of copper or aluminum and are insulated with a yellow or orange color. The yellow insulation is a standard color code used to identify specific types of circuits and functions in electrical systems.

The use of yellow wires is governed by international standards, including the IEC 60204 standard for industrial control systems and the IEC 60364 standard for electrical installations. These standards specify the color coding for different types of circuits, such as power, control, and signal circuits. Yellow wires are often used for control circuits, which are used to operate machinery, equipment, and other devices.

In addition to their use in industrial and commercial applications, yellow wires are also commonly used in residential settings for low-voltage systems such as audio and video equipment. In these applications, yellow wires are often used for ground or shield circuits, which are used to protect against electrical interference and ensure proper operation of the equipment.

Overall, keltajohtimilla are an essential component of electrical systems, providing a clear and standardized way to identify different types of circuits and functions. Their use helps to ensure the safe and reliable operation of electrical systems in a wide range of applications.
