All electrical systems are organized into power supply units. These devices convert electrical energy from the power grid or batteries into a usable form of electricity. Although there are many different types of electrical current, the two basic types are alternating current (AC) and direct current (DC), each with its own characteristics suited to specific applications.
AC power is commonly used to transmit energy over long distances because it reduces power loss, while DC power is suitable for electronic devices that require a stable voltage supply. Understanding this difference helps in selecting the appropriate power source for household appliances, office equipment, and industrial systems.
CVV cables and CXV cables are commonly used in Vietnam. So what is the difference between these two types of cables?
Are HELU's electrical cables compatible with the CVV/CXV cable standards on the market? Is there anything that sets HELU's electrical cables apart?
What is a LAN? How many types of LAN cables are there, and what role do they play in network connections? Let’s find out more in the following article!
Fiber optic cables use light to transmit signals, allowing signals to travel farther at high speeds. Let’s explore some basic information about fiber optic cables in the following article.

In industrial automation systems, dozens—or even hundreds—of devices such as PLCs, sensors, and inverters need to communicate with one another over distances of up to thousands of meters. RS485 cables are the physical components responsible for transmitting those signals—they are stable, resistant to interference, and much more cost-effective than industrial Ethernet solutions.
How does the RS485 standard differ from RS232? Let’s explore its features, operating principles, and the compatible cable lines from HELU in the following article!
When learning about the diameter of electrical cables, users need to be familiar with the AWG (American Wire Gauge) system and the metric system. The AWG system is commonly used in the United States to indicate the diameter of electrical conductors, while the metric system is used in many other parts of the world.
