Features

01

High safety

- Good insulation performance: The insulation layer of household wiring can effectively isolate the current and prevent the risk of electric shock to users. Insulating materials usually have high insulation resistance and voltage resistance, ensuring that the wires will not leak under normal use and certain environmental conditions.

- Flame retardancy: High-quality household wiring has certain flame retardancy. When the wires heat up and catch fire due to overload, short circuit, etc., they can slow down the spread of the flame, giving people more escape time and reducing fire losses. For example, flame-retardant wires with the prefix "ZR" can automatically extinguish after leaving the open flame.

- Standard current carrying capacity: The current carrying capacity of the wire is designed according to the power demand of household electrical equipment, which can ensure that the wire will not heat up due to overload under normal use, reducing the risk of fire caused by overload.

02

Strong applicability

- Multiple specifications are available: There are multiple specifications of household wiring, such as 1.5 square millimeters, 2.5 square millimeters, 4 square millimeters, 6 square millimeters, etc., which can meet the power demand of different electrical equipment. For example, 1.5 square millimeters of wire are often used in lighting circuits; 2.5 square millimeters of wire are suitable for ordinary sockets; 4 square millimeters of wire can be used for high-power electrical equipment, such as air conditioners, electric water heaters, etc.

- Easy to install: Home decoration wires are usually soft, easy to bend and pass through pipes, which is convenient for wiring construction in home decoration. At the same time, the length of the wire can also be cut as needed to adapt to different installation scenarios.

03

Good durability

- Anti-aging performance: The insulation layer and conductor of the wire have good anti-aging performance, and can maintain good electrical and mechanical properties during long-term use. Under normal use conditions, the service life of home decoration wires can generally reach more than 15-20 years.

- Corrosion resistance: For some environments that may be exposed to corrosive substances such as water, oil, acid and alkali, the insulation layer and sheath of home decoration wires have certain corrosion resistance, which can ensure the normal use of wires.
