Crosslinked cable is short for crosslinked polyethylene (XL-PE) insulated cable.Crosslinked cables are suitable for transmission and distribution lines with power frequency ac voltage up to and including 500KV.At present, most of the high voltage cables are insulated by crosslinked polyethylene.
Crosslinked cables usually refer to cables whose insulation is made of crosslinked materials.The most commonly used material is crosslinked polyethylene (XLPE).The crosslinking process is to make the linear molecular structure of polyethylene (PE) through a specific processing way to form the shape of the crosslinking polyethylene reticulated line structure.As a result, the long-term allowable working temperature is raised from 70℃ to 90℃ (or higher), and the short-circuit allowable temperature is raised from 140℃ to 250℃ (or higher), which greatly improves the actual performance under the premise of maintaining its original excellent electrical performance.
There are several advantages for XLPE. Wenchang provide many kinds of XLPE for your choose.
Such as UL3265, UL3266,UL3167,UL3173,UL3182,UL3194,UL3195,UL3196,UL3199,UL3236 etc.
(1) Excellent mechanical and physical properties, good environmental stress cracking resistance, excellent wear resistance, more than PVC and PE can withstand concentrated mechanical stress.
(2) Resistant to various chemical solvents, stable in a variety of corrosive media around.
(3) The outer diameter of irradiated crosslinked polyolefin insulated wire is smaller than that of all-polyvinyl chloride insulated wire with the same specification section, which can reduce the pipe diameter used in pipe threading construction, or wear more wires under the same pipe diameter condition, thus reducing the construction installation cost.
(4) Irradiation crosslinked polyolefin insulated wire product is much lighter than PVC insulated wire product, which is more convenient for installation and transportation, reducing labor intensity and transportation cost.
(5) The maximum rated temperature of irradiated crosslinked insulated wire can reach 125℃ during long-term operation, and the carrying capacity is greater than that of PVC insulated wire.
(6) It does not release corrosive gases or toxic gases during combustion, and will not cause secondary damage. It is a new type of environmental protection product in line with modern fire safety requirements.
(7) Good electrical performance, insulation resistance is much higher than PVC cable, and medium loss Angle tangent is very small, basically does not change with the change of temperature.
