What is XLPE insulated cable?
The cross-linked polyethylene insulated cable transforms the molecular structure of polyvinyl chloride from a linear molecular structure to a main network molecular structure. Greatly improve its heat resistance and mechanical properties, reduce its shrinkage, so that it will not melt easily after being heated. It has been widely used in network power systems, power distribution and transmission. It has incomparable electrical performance with PVC sheathed cable.

Conductor:Copper conductor conforming to IEC 60228, Class 2 standard Appearance:round or special-shaped conductor Insulation:XLPE (cross-linked polyethylene) rated temperature is 90℃, a variety of colors are available Sheath:PVC or FR-PVC type ST2 conforming to IEC 60502, black or red or customized
XLPE insulation performance
XLPE insulation materials have endless properties and applications in any industry. Especially when applied to the cable industry, it can take advantage of its unique performance better than other types of cables. The following are its basic attributes and advantages.
The molecular characteristics of the cross-connection make XLPE stronger, increase the service life, and at the same time increase the low-temperature impact strength, environmental stress cracking and abrasion resistance.
The XLPE insulating layer has better heat resistance and will not melt even at a temperature of 120 degrees Celsius.
It has excellent moisture-proof and flame-retardant properties.
It has excellent dielectric strength and low dissipation factor at all frequencies, making it an ideal insulator.
The weight of XLPE insulated cable is very light and it is more comfortable to use.
The connection of XLPE cables saves time than any other traditional cables.
What is the difference between PVC and XLPE cables?
We all know that the cable carries the function of indoor and outdoor power transportation, so its importance can be imagined.
In response to this situation, we have developed XLPE insulated cables to reduce the risk of power transmission. Let’s compare:
1. Conductor: Both PVC and XLPE use copper conductors as conductors, and PVC and XLPE are used as outer protective materials for the outer layers, respectively. 2. Thermal life: The thermal life of PVC is 20 years, while that of XLPE is 40 years. 3. Current carrying capacity: XLPE insulated cables have high carrying capacity, strong overload capacity, and places where power transmission is intensive. 4. Products after combustion: When PVC is burned, it will decompose and release a large amount of black smoke and toxic gas, which will cause fatal harm to human body. In addition, burning materials will seriously affect the insulation of the equipment and cause secondary hazards. When XLPE burns, it will not produce halogen toxic gas, and will not cause any harm to human body machines
Application
The use characteristics of the XLPE insulation layerof XLPE insulated power cables make the cables suitable for power transmission and distribution systems with a rated voltage up to 15kV. And it can be used in the open air for fixed installation or landfill installation without any problems during use. It has a use time of up to 50 years and has unparalleled advantages.
