What is XLPO cable?
XLPO cable, or cross-linked polyolefin cable, is a special type of insulating material cable in the cable industry, which cross-links polyolefin materials (e.g., ethylene vinyl acetate copolymer EVA) by chemical or physical methods to form a three-dimensional mesh structure, thus significantly improving the thermal stability, mechanical properties and chemical resistance of the cable.
What is XLPE cable?
XLPE cables, or Cross-Linked Polyethylene cables, are centered on the use of Cross-Linked Polyethylene in the insulation layer. The cross-linking process alters the original linear molecular structure of polyethylene by chemically or physically forming a stable three-dimensional mesh between the molecules. This cross-linking process significantly enhances the heat resistance, mechanical strength and chemical stability of the material.
The following is a detailed description of the characteristics of XLPO cable, application and comparison with XLPE cable:
XLPO cable characteristics:
High temperature resistance: XLPO cable can withstand high operating temperatures, usually ranging from -40°C to 150°C, which makes it suitable for some electrical equipment in high temperature environments.
Low smoke and halogen free: XLPO materials are usually designed as low smoke and halogen free types, which means that they produce less smoke when burned and do not contain halogen elements, reducing toxic smoke and corrosive gases in the event of a fire, which facilitates the safe evacuation of people and the protection of equipment.
Flame retardant: XLPO cables have good flame retardant properties that slow down the spread of fire and comply with safety standards in all types of construction, transportation and industrial areas.
Mechanical properties: The cross-linking process enhances the mechanical strength and abrasion resistance of the cable, making it more resistant to bending and stretching, making it suitable for use in complex installation environments.
Chemical resistance: XLPO material has good resistance to many chemicals, suitable for use in chemical, petroleum and other corrosive environments.
XLPO cable application areas:
Electric Vehicle Charging: As mentioned earlier, 2.5mm² XLPO cables are suitable for electric vehicle charging and can effectively cope with the challenges posed by outdoor environments and frequent use.
Automotive interior wiring: Inside automobiles, especially where there are strict requirements for fire protection, low smoke and non-toxicity, such as instrument panel wiring, power system connections, etc.
Rail transportation: electrical systems inside rail vehicles such as subways and trains require cables that are both safe and durable, and XLPO cables are the ideal choice.
Industrial automation: In industrial environments with high temperatures, high humidity and risk of chemical corrosion, XLPO cables provide stable electrical connections.
Building wiring: Especially in public buildings, hospitals, and schools where fire safety is critical, XLPO cables meet high standards with their low-smoke, halogen-free, flame-retardant properties.
What is the difference between XLPO cable and XLPE cable?
