The difference between strong electricity and weak electricity

The main difference between strong electricity and weak electricity is the voltage range: strong electricity is higher than 36 volts, and weak electricity is lower than 36 volts. Strong electricity is mainly used for power and lighting, while weak electricity is used for information transmission and control. Strong electricity has greater safety hazards, while weak electricity is relatively safe. Strong electricity uses multi-stranded copper core wires, and weak electricity uses single-strand or twisted-pair wires. During construction and installation Strong and weak current systems are wired separately. The frequency of strong current is usually 50 or 60 Hz. The frequency of weak current is diverse. The transmission distance of strong current is shorter and the transmission distance of weak current is longer.

The difference between strong electricity and weak electricity

Electric energy can be divided into strong electricity and weak electricity according to its use and voltage level. . Strong electricity is mainly used for power and lighting, while weak electricity is mainly used for information transmission and control.

Voltage Range

The most significant difference is the voltage range. Strong electricity usually refers to electrical energy with a voltage higher than 36 volts, while weak electricity refers to electrical energy with a voltage below 36 volts.

Use

Strong electricity is mainly used for electrical equipment in industry, commerce and homes, such as motors, air conditioners, lighting fixtures and electric heaters. Weak current is used in data transmission, communications, control systems and security systems such as telephones, computers, networks and security equipment.

Safety Risk

Strong electricity poses greater safety risks because high voltage may cause electric shock, fire and explosion. Therefore, strong current lines and equipment need to be installed and used in strict accordance with regulations, and necessary safety measures must be taken. Weak electricity is relatively safe and generally does not cause danger.

Types of wires

The types of wires used for strong current and weak current are also different. Powerful electricity usually uses multi-stranded copper core wires to withstand high currents and voltages. Weak current uses single copper core or twisted pair wire to reduce signal interference and attenuation.

Building installation

In building installation, strong current and weak current systems are usually wired separately. Strong current wiring is usually located in the ceiling or walls, while weak current wiring is located in the floor or dado. This separation helps prevent interference and ensures a safe and reliable system.

Other differences

In addition to the above differences, there are some differences between strong electricity and weak electricity:

• The frequency of strong electricity is usually 50 or 60 Hz, while the frequency of weak current can be selected in various ways.
• Strong electricity is mainly a one-way current, while weak electricity can be DC or AC.
• The transmission distance of strong electricity is relatively short, while the transmission distance of weak electricity can be very long.
