What Is A Strong Wire? What Is A Weak Wire?

Strong electricity: Refers to points in the power system, such as 220V lighting electricity and industrial electricity above 1,000V. Strong current is characterized by high voltage, low frequency and high current

Weak current: refers to the current and voltage required to transmit signals. Weak current is characterized by small current, high frequency and low voltage.

Strong wires mainly refer to TV, air conditioner, lighting lines, while weak wires mainly include telephone lines, network lines, monitoring lines and other lines.

Weak electrical signals are low-voltage electrical signals. They cannot be bundled with high-voltage wires. Otherwise, they will interfere with each other and interrupt the transmission signal. Generally, the terminals of communication lines and the terminals of high-voltage lines must be separated by at least 450mm.

In the cassette for laying the wires, the distance between the strong and weak wires is generally about 5 cm. If the distance is too close, the signal transmission of the weak current will also be affected.

Weak wires should avoid strong wires (power wires), and the horizontal distance between power wires and sockets and TV wires and sockets should be greater than or equal to 50cm; the wires under the socket should be about 30cm from the ground. Large spacing, but must be separated by 50cm, which depends on the actual wiring situation.

Weak wires are usually run on roofs or under floors. For moisture protection and replacement, a solid sleeve is added to the periphery of the production line (check for shorts or open circuits before adding sleeves).
